SS-2不同压力开关操作手册说明书

“SS-2 DIFFERENTIAL PRESSURE SWITCH OPERATION MANUAL OMP# 4202XDX000The pressure switch “BLOCK AND BLEED” action is the same when the instrument pressure is connected to the “LO IN” port and “HI IN” port is left unused. For this mode of operation, the switch acts as a normally closed valve and is called a low switch. When normal differential pressure is acting on the piston, the center O-ring on the spool is between the “HI IN” port and the “OUT” port thus preventing the instrument pressure from passing to the “HI PORT” of the switch body, but allowing it to flow from the “LO IN” port to the “OUT” port of the switch body. When the differential pressure decreases to an abnormal level, the spring force shifts to the spool and the middle o-ring on the spool becomes positioned between the “LO IN” port and “OUT” port. Pressure at the “LO IN” port is “BLOCKED” from entering the “OUT” port and pressure at the “OUT” port “BLEEDS” to atmosphere from the “HI IN” port. The Ruelco “SS-2” pneumaticdifferential pressure switch is a threeway block and bleed valve that isoperated by pressure acting on a pistonopposing an adjustable spring force. Itfunctions as either a normally closed ornormally open valve depending onthrough which the two ports theinstrument pressure is supplied. Theseports are marked as “HI IN” or “LO IN”on the switch body. The output port,marked “OUT” on the switch body, isthe same for either mode of operation.The difference between the pressuresacting on the upstream and downstreamsensing ports is the differential pressurewhich causes the valve to operate.When the instrument supply pressure isconnected to the “HI IN” port, the switchoperates as a normally open valve and iscalled a high switch. If the differentialpressure acting on the piston is at normallevels, it is insufficient to overcome thespring force. The middle o-ring on thespool is positioned between the “LO IN”and the “OUT” port, thus preventing theinstrument pressure from passing to the“LO IN” port of the switch body, butallowing it to pass from the “HI IN” portto the “OUT” port. When the differentialpressure acting on the piston becomeslarge enough to overcome the springforce, the spool shifts and the center o-ring moves between the “HI IN” portand the “OUT” port. Instrument pressure at the “OUT” port and downstream “BLEEDS” to atmosphere thru the “LO IN” port while supply pressure at the “HI IN” port is blocked from entering the “OUT” port.Changing the differential pressure value when the switch is used as either a high or low is done by altering the force of the spring. Changing the spring force is accomplished by turning the spring cap to increase or decrease the spring compression.2.0 INSTALLATION: 2. Small pliers.3. High quality silicone base lubricant.The “SS-2” differential can be panel mounted (with optional panel mount nut) or supported by piping from the sense port in either vertical or horizontal positions. If the switch is mounted horizontally, it is recommended that the small vent hole in the side of the switch body be oriented in a downward position. This will prevent any debris from accumulating in the spring cavity or above the sense piston. 4. An appropriate safety solvent. 3.1 PARTIAL DISASSEMBLY A) Spring Removal3.1.1)If the switch is installed in an operating instrument system, it is not necessary to remove any instrument supply or sense pressure. If the unit is a high switch, it will trip when changing the spring; if it is a low switch, then it will not. So precautions should be taken to avoid any unwanted reactions in the instrumentation system.Proper pipe thread sealant should be used on any pipe fittings threaded into the pressure switch ports. If stainless steel fittings are used, a sealant that will prevent galling is required. The supply gas flowing through the switch body should be filtered and free of large particles. If compressed air is used, it does not have to be lubricated. If natural gas is used as the instrument pressure, then it should contain as little condensate or crude oil as possible. This will extend the life of the seals. When the switch is mounted using the 1/4” NPT base connection and the instrument pressure ports are not in the desired position after the base connection is adequately tightened, DO NOT loosen the body from the base to re-position the ports. Instead, remove the switch and re-make the 1/4” NPT connection.3.1.2) To obtain access to the spring(Item 2), rotate the lock ring (Item 4) clockwise to loosen it from the spring cap (Item 1).3.1.3) Rotate the spring cap (Item 1)counterclockwise until it is disengaged from the switch body (Item 8).3.1.4) Remove the spring from itscavity in the switch body.3.0 DISASSEMBLY (See Spec Sheet)3.1.5) Follow the procedures in repairand assembly section (Steps 4.1.4 and 4.14) of this manual to re-install the spring.Tools and materials required for proper disassembly, repair and assembly are as follows: 1. 7/8” and 1” open end wrenchesor two crescent wrenches of adequate size.B)Piston Removal3.1.6)If the switch is panel mounted, itis not necessary to remove itfrom the panel. It will benecessary to disconnect anypiping or tubing from the basethat would prevent the base frombeing removed. When the switchis supported by the ¼” NPTconnection on its base (Item 12),disconnect any piping or tubingfrom the switch body that wouldprevent its removal from theswitch base. CAUTION: Be surethat all instrument or sensepressures are completely bled tozero before disconnecting anypiping or tubing.3.1.7)Use the appropriate wrenches tohold and loosen the base from theswitch body.

ELECTRIC CONNECTION (diagram B)The electric connection must be performed by qualiﬁ ed personal in compliance with regulation of each country.Before doing manipulations inside the device, it must be disconnected from the electric supply.Wrong connection could spoil the electronic circuit.The manufacturer declines all responsability in damages caused by wrong connections.Check if power supply is between 115-230V.If you have purchased the unit without cables follow diagram B:• Use cables type H07RN-F 3G1 or 3G1,5 with section enough to thepower installed.• Do the pump connection U, V and .• Do the power supply connection L1, N and .• The earth conductor must be longer than the others. It will be the ﬁ rst one to be mounted during the assembly and the last one to be dis-connected during the dismantling. T he earth conductors connec-tions are compulsory!CONTROL PANEL (diagram C)The meanings of the different control panel elements are summarized on the following tables, where:• O means lit LED light.• ( ( O ) ) means slow-ﬂ ashing.• (((O))) means fast-ﬂashing.STARTUP (diagram C)Before starting the device please read the previous sections, espe-cially “Hydraulic Installation” and “Electrical connection”.Follow next steps:1. Start the device by pressing .2. Only for type SG12 set the pump rated current intensity value.- Press during 3 seconds.- The current intensity value is displayed on screen, LED A lights up and display is ﬂ ashing.- By mean of and is adjusted the rated current reﬂ ected in the characteristics plate of the motor. See Note 1.- Press for validation.3. Set the cut-in (start) pressure:- Press during 3 seconds.- The start pressure value is displayed on screen, LED START lights up and display is ﬂ ashing.- By mean of and is adjusted the start pressure from 0,5 to 7 bar.- Press for validation.4. Set the cut-out (stop) pressure:- Press during 3 seconds.- The stop pressure value is displayed on screen, LED STOP lights up and display is ﬂ ashing.- By mean of and is adjusted the stop pressure from 1 to 8 bar.- Press for validation.5. The unit is ready to operate but more optional adjustments can be set through basic and advanced MENUS. See the next chapter.Remark 1: it is important to introduce exactly the rated current speciﬁ ed on the nameplate of the pump.BASIC MENU + (diagram C)- Press simultaneously + during 5 seconds.- By mean of or the values can be changed.- Press for validation.ADVANCED MENU + +- Press simultaneously + + during 5 seconds.- By mean of or the values can be changed.- Press for validation.Remark 2:Basic SWITCHGENIE can only detect dry-running operation through the minimum pressure. This means that plumber must determine the water column of the installation, the start pressu-re of the pump and place the minimum pressure below the start pressure.It can also occur that pumping system is running out of its curve so that the pump is unable to provide the minimum pressure because the ﬂ ow requirement is excessive. In this case SWITCHGENIE would activate a false dry-running alarm.If these concepts are not clear, it is preferable not conﬁ gure this protection or install the SWITCHGENIE 12 with accurate and easy setting of dry-run detection.SYNCHRONISATION (ONLY FOR SWITCHGENIE 12)SWITCHGENIE 12 can be synchronized to another unit SWITCHGENIE 1managing and protecting 2 pumps operating in cascade with alternated starting sequence. Next steps must be followed:1. SET identical cut-in and cut-out pressures in both units.2. GO TO ADVANCED MENU: + +- In step 2in the other unit (this one will be the slave).- In step 3: select identical parameters of differential d.XX.3. Press repeatedly until exit the ADVANCED MENU.4. Press in order to disable the units. Is displayed “OFF”.5. Press again in both units in order to activate the synchronization.Remark 3: after 10 cycles the unit conﬁ gured E01 will display pressu-re and the unit conﬁ gured E02 will display current in Amps.ACCURATE DRY-RUNNING DETECTION (diagram C)In the SWITCHGENIE 12 model it is enough to set the rated current of the pump in order to activate the overcurrent and dry-running protection. However, the accuracy of dry-running detection can be improved by the activation of DR1 parameter in the ADVANCED MENU. The following steps must be followed:1. Drain the hydraulic installation and verify that the hydropneumatic tank is inﬂ ated to the required pressure.2. Go to the ADVANCED MENU:- Press simultaneously + + during 5 seconds.- Press 7 consecutive times to accept and go to the next step until reaching dr0.- Using , set dr1.3. Press and close all the valves.4. The pump will start, will ﬁ ll the installation and will stop at the cut-out pressure.5. Now, SWITCHGENIE 12 knows the current consumption curve of the pump.If you install a new pump this process should be repeated.If you enter the CURRENT INTENSITY MENU by pressing for 3 seconds all this process is invalidated because is predominant the rated current manually introduced.PRESSURE SENSOR CALIBRATIONIn case of wrong lecture of the pressure sensor it can be adjusted again. For the pressure sensor calibration is necessary to have a pressure gauge in the installation. Proceed following next steps:ZERO REGULATION1. Open the taps living the hydraulic net without pressure.2. Press simultaneously the buttons and until the display show0.0 ﬂ ashing.3. Press to validate.FULL SCALE1. Start the pump until cut-out of the pressure switch.2. Press simultaneously the buttons and till the display ﬂ asheswith a ﬁ gure.3. Adjust the pressure with the arrows push-buttons to get the pressuredesired.4. Press to validate.Remark 4: pressure sensor decalibration should not be a normal event.

pc30de压力开关说明书

pc30de压力开关说明书
pc30de压力开关(pc30d)是一种无源电磁触点式开关，具有超灵敏的压力感受器和阻尼转换器。

根据介质(protected particle)的不同，可选用以下类型：1.用于气体、液体等介质中；2.用于真空下工作的压力开关。

一、开关工作原理
在机械开关中，触点是指施加于气体、液体等介质的运动状态的触点。

压力开关所需的压力感受器，工作原理如下：当设备启动时，感应头接触高压信号而带动电磁缸高速旋转，同时触点上压紧弹簧使之产生回旋，带动压紧弹簧及压力传感器；当压力升高时，被控介质将释放出巨大的扭矩带动电磁缸高速旋转；当压力降低时，压力感受器弹簧产生一定的回旋，通过弹簧力的作用使被控介质释放气体或液体（或者蒸汽);压力改变时触点上压紧力自动改变感应头位置和大小。

二、基本组成
pc30de压力开关的基本组成由触发线圈、压力传感器、弹簧和触点组成。

其中触点为一种机械连接，工作于一定工作电压下，主要用于对介质直接施加压力。

对各种材料的压力传感器进行测量和转换。

弹簧与触脚组合在一起，以形成复位操作杆，用于控制开关动作和关闭操作。

弹簧和触脚通过橡胶连接在一起，用于橡胶密封。

触脚通过螺栓固定在弹簧座上。

三、使用注意事项
a.该开关可以工作在极低的工作温度下，且不会产生过大的振动。

b.该开关在工作时不会产生过载，且该设备具有自我保护功能，不会因为意外而损坏。

c.该开关具有压力自锁功能，可防止因误操作造成严重后果。

丹福斯（Danfoss）RT型号压力开关产品介绍说明书

RT Pressure switches incorporate a pressure controlled, single-pole change over swich where the contact position depends on the pressure in the connection port and the set value.The RT series consists of pressure switches, differential pressure switches and pressure switches for neutral zone regulation, all for general use within the industrial and marine segments. The series also covers safety pressure switches dedicated for steam boiler plants.For installations in which operation is particularly critical from safety and economic points of view, the use of fail-safe pressure switches is recommended.The use of gold-plated contacts is also recommended in such installations, provided operation involves only a few switching cycles or signal currents and voltages.Features• Simple design• High accuracy• High repeatability • Long operation life time• Available with all major marine approvalsData sheet | Pressure switch, RT Note:in addition we refer to the certificates, the copies of which can be ordered from Danfoss y CE marked in accordance with EN 60947-4/-5 for sale in Europey Further, the RT 19 , RT 30, RT 35, RT 112 W, RT 33, RT 31 and RT 32 series is CE markd in accordance with PED 97/23/EC, category IV, safety equipment.Approvals Overview/SurveyData sheet | Pressure switch, RTTechnical dataand code nos.When ordering, please state typeand code number.The type designationfor the letters below means:A: Unit suitable for the medium ammoniaL: Unit with neutral zonePressure switchesRT 113for manual setting;cover with windowsRT 116for tamper proof;cap and blank coverRT 262 ADifferential pressure switchPressure switches with adjustable neutral zoneDifferential pressure switches1)Supplied with ø6 / ø10 mm nipple. / 2)Non-snap action contacts (see spare parts and accessories, contact system 017-018166)3) With SPST and SPDT contact system for alarm and cut off function at 0.8 and 1 bar1) Supplied with ø6 / ø10 mm weld nipple1) Supplied with ø6 / ø10 mm weld nipple. / 2) With seal capPreferred versionsData sheet | Pressure switch, RT B: Safety units with external reset S: Safety units with internal resetThe designation letters mean:A: Units suitable for the medium ammonia.W: Units for control purposes.Pressure switches for steam plant, PED approved acc. to EN 12953-9 and EN 12922-11For rising pressureFor falling pressurePressure switches for low pressure steam plant (pressure monitoring)- not PED approvedTechnical data and orderingTechnical dataPreferred versionsData sheet | Pressure switch, RTMaterials in contact with the mediumMaterials in contact with the medium, PED approved switchesData sheet | Pressure switch, RTb. All other RT pressure switchesWhen the pressure falls to the set range value, contacts 1-2 make and contacts 1-4 brake. The contacts changeover to their original position when the pressure again rises to the set range plus the differential (see fig. 5).I. Alarm for falling pressure givenat the set range value.II.

RT 19, RT 30, and pressure switcheswith max. resetWhen the pressure exceeds the set range value, contacts 1-4 make and contact 1-2 brake. The contacts changeover to their initial position when the pressure falls to the range value minus the differential (see fig. 4). I.Alarm for rising pressure givenat the set range value.II. Alarm for falling pressure given at the set range value minus the differential.Units with max. reset can only be reset at a pressure corresponding to the set range value minus the differential, or a lower pressure.Data sheet | Pressure switch, RTExample 1An extra cooling water pump must start if the cooling water pressure falls below 6 bar, and must stop when the pressure exceeds 7 bar.Choose an RT 116 with a range of 1 – 10 bar and an adjustable differential of 0.2 – 1.3 bar.The start pressure of 6 bar must be set on the range scale. The differential must be set as the difference between the stop pressure (7 bar) and the start pressure (6 bar) = 1 bar. According to fig. 3, the differential setting disc must be set on 8.Example 2The burner on a steam boiler must cut out when the pressure exceeds 17 bar. Automatic restart must not occur.Choose an RT 19B with external reset. If extra safety is demanded, an RT 19S with internal max. reset can be used.The range is 5 – 25 bar and the differential is fixed at approx. 1 bar. The range scale must be set at 17 bar. After cut-out of the burner, manual reset is possible only when the pressure had fallen to the setting of 17 bar minus the differential: in this case, 16 bar and below.Example 3The min. permissible lubricating oil pressure for a gear is 3 bar. Reset must not be possible until the reason for oil pressure failure has been investigated. Choose an RT 200 with min. reset.The range value must be set while reading the range scale. Manual reset is possible only when the pressure has reached 3.2 bar (the differential is fixed at 0.2 bar or higher).Function (continuation)Functional description of RT unitswith fail-safe designFail-safe function for falling pressureFig. 5a shows a cross-section of a bellowselement for the RT 32W with fail-safe functionfor falling pressure. On rising pressure thecontact arm is actuated to break the connectionbetween terminals 1 and 2.On falling pressure the contact arm is actuatedto break the connection between terminals1 and 4. If a defect occurs in the bellows thesetting spring actuates the contact arm to breakthe connection between terminals 1 and 4, asin the case of falling pressure. This will occurirrespective of the pressure on the bellows.Fail-safe function for rising pressureFig. 5b shows a cross-section through a bellowselement for the RT 30W with fail-safe for risingpressure. On rising pressure the contact armis actuated to break the connection betweenterminals 1 and 2 .If a defect occurs in the inner bellows thepressure is led to the outer bellows. The outerbellows has an area three times as large as theinner bellows. The connection between terminals1 and2 becomes broken.If a defect occurs in the outer bellows, there willbe atmospheric pressure in the gap between thetwo bellows. This actuates the contact system tobreak the connection between terminals 1 and2. The important factor with the double bellowsdesign is the vacuum between the two bellows,and that in case of bellows break, no media willleak into the environment.Fig 5aFig. 5bData sheet | Pressure switch, RTPressure switches for liquid level control RT 1133. Connection to the side of the tankwith the RT 113 below the liquid levelWhere possible, this form of connection shouldbe used. If an air-absorbing liquid like oil isinvolved, it is preferable to 1 and 2. The resultingrange setting is the distance from the liquidsurface to the centre of the diaphragm housing.4. Connection in the tank with the RT 113above the liquid levelThis method is for use with air-absorbing liquidswhere connection type 3 is not possible. Theshortest horizontal tube length is determinedas described in 2. A shut-off valve is installedbetween the oil tank and water reservoir shownso that impurities can be drained from the waterreservoir through a bottom drain plug. Freshwater can then be poured into the reservoirthrough a filling connector in its top.The RT 113 pressure switch can be usedto control the liquid level in open tanks.Fig. 6 shows in principle, four different typesof installation.1. With air bell (see “Accessories”)For control purpose, the air bell should beinstalled 20 – 40 mm below the lowest liquidlevel. In addition, the tube between the RT 113and the air bell must be absolutely airtight. Ifonly an indication is required, the bell can beplaced 100 mm below the max. level. The RT 113must be set at 0 cm wg and the differential discon 1.2. Connection to the side of the tankwith the RT 113 above the liquid levelThe horizontal tube A must have a certain lengthin relation to the vertical tube B in order toensure reliable control. The length ofA can befound from fig. 7, using B and the range settingpressure C.Data sheet | Pressure switch, RT Application5. Setting knob 9. Range scale40. Neutral zone discRT-L pressure switches are fitted with a switch with an adjustable neutral zone. This enables the units to be used for floating control.The terminology involved is explained below.Floating controlA form of discontinuous control where thecorrecting element (e.g. valve, damper, or similar) moves towards one extreme position at a rate independent of the magnitude of the error when the error exceeds a definit positive value, and towards the opposite extreme position when the error exceeds a definite negative value.HuntingPeriodic variations of the controlled variable from the fixed reference.Neutral zoneThe interval in the controlled variable in which the correcting element does not respond (see fig. 13)The contact system in neutral zone units cannot be exchanged, as the contact system adjustment is adjusted to the other parts of the unit.Setting of neutral zoneThe range is set using the setting knob (5) fig. 8 while reading the range scale (9). The pressure set is the break pressure for contacts 1-4 (see fig. 13).The required neutral zone can be found in the diagram for the unit concerned. The position at which the neutral zone disc (40) must be set can be read from the lower scale in the diagram. The function can be seen in fig. 13.Data sheet | Pressure switch, RTExampleTogether with a VLT® static frequency converter, RT 200L neutral zone pressure switches can be used for the infinite control of a pump in, for example, a pressure boosting plant.In this case, the pump must be up and downregulated at 32 m and 25 m wg.The RT 200L must be set using the setting knob (5) fig. 8 page 9 at 3.5 bar (35 m wg) minus the fixed differential of 0.2 bar.The range setting is 3.5 - 0.2 = 3.3 bar.The neutral zone, 35 - 32 = 3 m wg,corresponding to 0.3 bar, must be set on the neutral zone disc (40) fig. 8 page 9. According to the diagram fig. 12 the disc setting is 1 or just over. A more accurate setting can be obtained by using the test setup shown in fig. 14.Setting of neutral zone© Danfoss | DCS (jmn) | 2016.06Data sheet | Pressure switch, RT IC.PD.P10.B6.02 | 520B7310 | 11ApplicationControl and monitoring of pressure differentials A differential pressure switch is a pressure controlled switch that cuts in and cuts out the current dependent on the pressure differential between the counteracting bellowselements and the set scale value. This unit is also available with an adjustable neutral zone (like the RT-L which is described on page 9.The setting disc (5) becomes accessible when the front cover is removed. The differential pressure is set by turning the disc with a screwdriver while reading the scale (9).For differential pressure switches with a changeover contact system, the contactdifferential is given as the differential pressure switches have a fixed differential. In units with an adjustable neutral zone, the neutral zone disc must also be set. See diagram in fig. 16.5. Setting disc 9. Range scaleSettingNote :When installing, the low pressure connection (LP) must always be upwards© Danfoss | DCS (jmn) | 2016.06Data sheet | Pressure switch, RT 12 | 520B7310 | IC.PD.P10.B6.02Functiona. Units with changeover switch (SPDT)b. Units with adjustable neutral zone (SPDTNP)If the differential pressure rises above the set value plus the differential, contacts 1-4 make.If the pressure falls by the amount of thedifferential (which is fixed in this unit), contacts 1-4 break. If the pressure falls to the neutral zone minus the differential, contacts 1-2 make. When the differential pressure rises again by an amount corresponding to the differential, contacts 1-2 break again.The contact function can be summed up as follows:I. Setting disc set for falling differential pressure.II. Neutral zone disc set for rising differential pressure.Example 1When the differential pressure exceeds 1.3 bar, a filter needs cleaning. The static pressure over the filter is 10 bar.According to the ordering table on page 4, the choice is an RT 260A (the RT 262A has a max. operating pressure on the low pressure side (LP) of 6 bar and is therefore not suitable for this application).Setting: Since a signal is required for rising differential pressure, the setting becomes 1.3 - 0.3 bar = 1.0 bar.Example 2The speed of a circulation pump must becontrolled to give a constant differential pressure of 10 m wg in a heating plant. The static plant pressure is 4 bar. The choice is an RT 262AL.The differential disc (5) fig. 15 page 13, must be set at 1 bar (10 m wg) minus the fixed differential of 0.1 bar, i.e. 0.9 bar. The neutral zone disc is factory-set (marked in red).I. Contacts make when differential pressure falls below the range scale setting.© Danfoss | DCS (jmn) | 2016.06RT 260A / RT 260ALRT 262A / RT 262A /RT 263ALData sheet | Pressure switch, RT IC.PD.P10.B6.02 | 520B7310 | 13Dimensions [mm] and weights [kg]Data sheet | Pressure switch, RT Spare parts and accessoriesSwitches1)At load types with low currents/voltages contact failure may occure on the silver contacts because of oxidation. In systems where such a contact failure is of great importance (alarm etc.), gold plated contacts are recommended.Contact systems for neutral zone units are not available as spare parts. Exchange not possible, as the contact system adjustment is adjusted to the other parts of the unit.The switch contacts are shown in the position they assume on falling pressure/temperature, i.e. after downward movement of the RT main spindle. The setting pointer of the control shows the scale value at which contact changeover occurs on falling pressure/temperature. An exception is switch no. 017-403066 with max. reset where the setting pointer shows the scale value at which contact changeover occurs on rising pressure.Data sheet | Pressure switch, RT© Danfoss | DCS (jmn) | 2016.06IC.PD.P10.B6.02 | 520B7310 | 15© Danfoss | DCS (jmn) | 2016.06Data sheet | Pressure switch, RT 16 | 520B7310 | IC.PD.P10.B6.02RT units have two mounting holes which become accessible when the front cover isremoved. Units fitted with switch 017-018166*) must be installed with the setting knob upwards. When installing differential pressure switches, the low pressure side (marked LP) must be installed upwards.The other pressure switches in the RT series can be installed in any position, expect that on plant subjected to severe vibrations it is advantageous to have the screwed cable entry downwards.*) Contact system with snap-action contact. See spare parts and accessories, page 13.Pressure connectionWhen fitting or removing pressure lines, the spanner flats on the pressure connection should be used to apply counter-torque.Steam plantTo protect the pressure element against temperature in excess to the maximumtemperature of the medium 150 °C (RT 113 90 °C), the insertion of water-filled loop is recommended. Water systemsWater in the pressure element is not harmful, but if frost is likely to occur a water-filled pressure element may burst. To prevent this happening, the pressure control can be allowed to operate on an air cushion.Media resistanceSee table of materials in contact with the medium. If seawater is involved, diaphragm pressure switches types KPS 43, KPS 45 and KPS 47 are recommended.PulsationsThe pressure switch must be connected in such a way that the pressure element is affected by pulsations as little as possible. A damping coil can be inserted (see “Accessories”). With strongly pulsating media, diaphragm pressure switches types KPS 43, KPS 45 and KPS 47 can be advantageous.Installation5. Setting knob 9. Range scale19. Differential setting disc SettingThe range is set by using the setting knob (5) while at the same time reading the scale (9). Tools must be used to set pressure switches fitted with a seal cap.In units having a fixed differential, the difference between cut-in and cut-out pressures is of course determined. On units having an adjustabledifferential the front cover must be removed. The differential disc (19) must be set in accordance with the diaphragm.Fig. 1. Positioning of unit© Danfoss | DCS (jmn) | 2016.06IC.PD.P10.B6.02 | 520B7310 | 17Selection of differentialTo ensure that the plant functions properly, a suitable differential pressure is necessary. Too small a differential will give rise to short running periods with a risk of hunting. Too high a differential will result in large pressure oscillations.Differential scale values are guiding.Installation。

Oildyne 压力开关产品说明说明书

OildynePressure SwitchesFor AC Power3.4-345 bar (50-5000 psi) RangeTypical ApplicationsPressure switches sense when a pre-selected fluid pressure is reached or lost and make or break an electrical circuit. Their operation can stop or start a machine’s cycle, actuate indicator lights or sequential operations. Properly installed, their operation is auto-matic and limited by your imagination and need.• Spring rangeDuplex models contain two separate switches which can be activated by one or two sensing ports depend-ing on the subplate configuration. See dimensional data for options.• environmentally resistantEnvironmentally resistant models are available on spe-cial order for certain hazardous location service.SubplatesSubplates are available for in-line mounting of Oildyne pressure switches. This allows further flexibility in mounting to existing equipment. Ports in 1/8 NPT or 7/16-20 (SAE-4) straight thread are standard. The duplex switch has two types of subplates, one with a port for each side of the switch, the other with one port only, for both sides of the switch.Pressure Switch Features• VersatileOur designs allow the switches to be used in any mounting orientation. They can sense hydraulic fluid pressure or air/gas pressure. A simple spring change allows the same basic switch to be used through a wide range of pressure settings.• durableHeavy-duty electrical contacts are rated for 15 amps at 125, 250 or 460 VAC. Normally open and normally closed contacts are provided.• reliableRepeatability is accomplished through a combination of a PTFE seal and a hardened, nickel-plated steel piston. This use of low-friction materials and the de-sign of the unique PTFE seal (or diaphragm*) prevents the piston from sticking. Repeatability, sensitivity and reliability are excellent. Limited piston movement pre-vents inertial forces from damaging the piston stop.*Used for lower pressure differential applications.Single Switchduplex Switchtriplex SwitchPRESSURE SETTING EASYMAKES CHANGINGADJUSTING SCREW LEAK PROOF OPERATION O-RING SEAL FOR1/2" PIPE CONDUIT CONNECTIONALL ALUMINUM CONSTRUCTIONELECTRICAL CONNECTIONSFOR ACCESS TOEASILY REMOVED COVER AND NORMALLY CLOSED CONTACTSSWITCH WITH NORMALLY OPEN HEAVY DUTY ELECTRICALAND ZERO LEAKAGE MINIMUM FRICTION PTFE SEALS FOR SPRINGDRAIN LINES NEEDEDSEALED PISTON, NO DISC OR DIAPHRAGMSINTERED METAL STAINLESS STEEL construction44Catalog HY22-1121/USfeatures and applications Pressure SwitchesParker Hannifin Corporation Oildyne DivisionMinneapolis, MN 55428 USA45DimensionsSingle Pressure SwitchSubplates (Single & duplex)Catalog HY22-1121/USdimensions Pressure SwitchesParker Hannifin Corporation Oildyne DivisionMinneapolis, MN 55428 USA46DifferentialThis is the pressure required to open and close theswitch contacts.
