Float-type level switches are generally able to handle high-temperatureapplications, and sometimes prove useful for close interface detection.Floats can operate up to three switching elements. Independent switching levels may be obtained with tandem floats. Consult the factory for special float-switching arrangements.Float-Operated Level Switches Model Series 108/208 and 400The float rides on the process liquid surface, precisely tracking liquid surface motion.Rising liquid level lifts the float via a pivot mechanism, sliding the attraction sleeve down inside the enclosing tube and out of the magnetic field to deactuate the electrical or pneumatic switch (signaling liquid presence).Subsequently, falling liquid level lowers the float, drawing the attraction sleeve into the magnetic field to actuate the electrical or pneumatic switch (signaling liquid absence). Float-type level switches are generally able to handle high-temperature applications.ActuatedDeactuatedSwitching Element Actuated MagneticField Engaged Attraction Sleeve Up CounterweightSwitching Element Deactuated C Common NC Normally Closed NO Normally OpenBias Spring Enclosing TubeC Common NC Normally Closed NO Normally OpenBias Spring Enclosing TubeMagneticFieldDisengaged Attraction Sleeve DownLevel DifferentialActuatedDeactuatedCommon Normally Open Normally Closed Pivot Bias Spring MagnetAttraction Sleeve Enclosing TubeFloatSwitching Element Level DifferentialActuatedDeactuatedDisplacer controls offer alternative features to the float-operated control. The sensor is a weight (displacer), heavier than the liquid, that is suspended by a spring. When liquid contacts the displacer, a buoyancy force is produced, which causes the effective weight of thedisplacer to change. This causes the spring to retract slightly to a new equilibrium position. When the spring retracts, the attraction sleeve also moves upward into the field of the external magnet, thus overcoming the force of the bias spring and actuating the switching element.This principle provides for narrow or wideswitching differential, and allows switching point alteration by moving the displacer(s) up or down the suspension cables.Displacers may be arranged in combinations of narrow and wide differential to operate up to three switching stages. Displacer controls operate under higher pressure conditions than float-operated switches.Displacer-Operated Level SwitchesModel Series 700, 730, 740, 750 and 800Common Normally Open Pivot MagnetAttraction Sleeve Enclosing Tube DisplacerBias Spring Normally Closed Suspension Rod / Cable Extension Spring Level DifferentialSwitching ElementGeneral●Rugged carbon steel or stainless steel construction●Five-year manufacturer’s warranty●Quick, worldwide delivery●All ASTM materials (see page 57)●Quality management system is registered to ISO-9001:2000Standard Chamber Materials●All SOR level switch chambers are constructed using ASTM grade materialswith full material certification.

Pressure and Vacuum Switches for Process ApplicationsForm 216SOR ® Pressure Switchesare rugged ﬁ eld-mounted instruments. Thepressure sensing element of the SOR pressure switch is a force-balance, piston-actuated assembly. The sensing element is sealed by a ﬂ exible diaphragm and a static o-ring. A wide selection of wetted parts materials for media compatibility and containment are available. A metal diaphragm may be welded to thepressure port for certain applications, thereby eliminating the o-ring.Application InformationThe SOR pressure switches in this catalog are suitable for a variety of process applications. Basic models with standard wetted parts are normally suitable for air, oil, water and non-corrosive processes. See the Quick Selection Guide on pages 4 and 5. Speciﬁ c application requirements can normally be met by selecting optional components, such as switching elements, diaphragm systems and pressure ports. See How to Order on page 3. Certain applications may require customized specials. Consult the SOR representative in your area or the factory.This catalog describes switches that are: • General Purpose • Weathertight• Conventional Explosion ProofOther speciﬁ c types of switches available through your SOR representative are:• Hermetically Sealed (for hazardous locations)• Pivot Seal (for high shock pressuresand cycle rates)• Differential Pressure• Temperature (remote and direct mount)• Electronic and Mechanical Level • Electronic Pressure12L6B36NNFeatures SwitchesComplete Product LineStandard models and customized specials cover pressure range from30 inches Hg VAC to 4000 psi.Robust ConstructionRugged, high-cycle rate tolerance, long life, not critical to vibration, high overrange and proof pressures, excellent corrosionresistance to hostile environments.

It is expressed for increasing pressure.Set PointThat discrete pressure at which the pressure switch is adjusted to actuate/deactuate on rising or falling pressure. It must fall within the adjustable range and be called out as increasing or decreasing pressure.Dead BandThe difference in pressure between theincreasing Set Point and the decreasing Set Point. It is expressed as typical, which is an average with the increasing Set Point at mid-range for a pressure switch with the standard K switching element. It is normally ﬁ xed (non-adjustable).Fire-SafeThe ability of a welded seal pressure sensor to contain the process at elevated temperatures up to 1200°F at the rated overrange pressure, unsupported by the body of the pressure switch.Hermetically SealedA welded steel capsule with glass-to-metal, factory-sealed electrical leads that isolates the electrical switching element(s) from the environment.OverrangeThe maximum input pressure that can be continuously applied to the pressure switch without causing permanent change of Set Point, leakage or material failure.SwitchesGlossary of T ermsSOR recognizes that there is no industry convention with respect to terminology and deﬁ nitions pertinent to pressure switches. This glossary applies to SOR pressure switches.Proof PressureThe maximum input pressure that can be continuously applied to the pressure switch without causing leakage or catastrophic material failure. Permanent change of Set Points may occur, or the device may be rendered inoperative.RepeatabilityThe ability of a pressure switch to successively operate at a Set Point that is approached from a starting point in the same direction and returns to the starting point over three consecutive cycles to establish a pressure proﬁ le.Repeatability on SOR switches will be smaller than 1% of full scale per ISA/ANSI S51.1. SPDT Switching ElementSingle-Pole, Double Throw (SPDT) has three connections: C — Common, NO — Normally Open and NC — Normally Closed, whichallows the switching element to be electrically connected to the circuit in either NO or NC state.DPDT Switching ElementDPDT is two synchronized SPDT switching elements which actuate together at increasing Set Point and deactuate together at decreasing Set Point. Discrete SPDT switching elements allow two independent circuits to be switched; i.e., one AC and one DC.The synchronization linkage is factory set, and is not ﬁ eld adjustable. Synchronization is veriﬁ ed by connecting test lamps to the switching elements and observing them go “On” simultaneously at actuation and “Off” simultaneously at deactuation.6NN-K5-M4-C2A-YY This table is a listing of piston-spring combinations and the corresponding adjustable ranges, dead bands, overrange and proof pressures. Adjustable range is expressed for increasing pressure; the Set Point must be within the adjustable range. Dead band is expressed as typical. See Dead Band Considerations on page 8.1. Dead band values are expressed as typicalexpected at mid-range with the standard Kswitching element assembly installed.

Level Switches are available for a range of industrial applications. An ATEX-certified option for potentially explosive atmospheres is available.NOTE: If you suspect that a product is defective, contact the factory or the SOR ®Representative in your area for a return authorization number (RMA). This product should only be installed by trained and competent personnel.Level SwitchesGeneral InstructionsDesign and specifications aresubject to change without notice.

Floats are attached to a mechanical linkage. When rising liquid level meets the float, buoyancy lifts the linkage and positions the attraction sleeve up in the enclosingtube. Upward movement of the attraction sleeve positions it within the magnetic field generated by the external magnet.Magnetism pulls the external magnet in toward the attraction sleeve, and the external magnet is tightly engaged against the enclosing tube actuating the switching element. When liquid level falls, the attraction sleeve drops out of the magnetic field allowing the float to pull the magnet away from the enclosing tube, deactuating the switch. NOTE: Float-type level switches are generally able to be used in high-temperature applications, and sometimes prove useful for close interface detection.NOTE: Floats are able to operate up to three switching elements. Independent switching levels can be obtained with tandem fl oats. Consult the factory for special fl oat switching arrangements.Float-Operated Level Switches - VerticalSwitching ElementCommonNormally OpenNormally ClosedPivotBias SpringMagnetAttraction SleeveEnclosing TubeFloatLevel DifferentialActuatedDeactuatedDisplacer controls offer alternate features to the float-operated control. The sensor is a weight (displacer), heavier than the liquid, which is suspended by a spring.When liquid contacts the displacer, a buoyancy force is produced, which causes the effective weight of the displacer to change. This causes the spring to retract slightly to a new equilibrium position.When the spring retracts, the attraction sleeve also moves upward into the field of the external magnet, thus overcoming the force of the bias spring and actuating the switching element. The switching mechanism operates the same as with vertical float-operated level switches.NOTE: This principle provides for narrow or wide switching differential, and allows switching point alteration by moving the displacer(s) up or down the suspension cables.NOTE: Displacers can be arranged in combinations of narrow and wide differential to operate up to three switching stages. Displacer controls operate under higher pressure conditions than fl oat-operated switches.Displacer-Operated Level Switches - VerticalSwitching ElementCommonNormally OpenNormally ClosedPivotBias SpringMagnetAttraction SleeveEnclosing TubeExtension SpringSuspension CableDisplacerLevel DifferentialActuatedDeactuatedSwitching ElementActuatedMagnetic FieldEngagedAttraction Sleeve Up CounterweightEnclosing TubeBias Spring NO Normally Open NC Normally Closed C CommonSwitchingElement DeactuatedMagnetic Field Disengaged Attraction Sleeve DownBias Spring NO Normally Open NC Normally Closed C Common Level Differential Enclosing TubeThe float rides on the process liquid surface, precisely tracking liquid surface motion.Rising liquid level lifts the float via a pivot mechanism, sliding the attraction sleeve down inside the enclosing tube and out of the magnetic field to deactuate the electrical or pneumatic switch (signaling liquid presence).Falling Level The float is connected to a mechanical linkage which positions the attraction sleeve up in the enclosing tube when the float is not supported by liquid. Positioned at the top of the enclosing tube, the attraction sleeve is within the magneticfield generated by the external magnet. Magnetism pulls the external magnet in toward the attraction sleeve, and the external magnet is tightly engaged against the enclosing tube. While the external magnet is held against the enclosing tube, the switching element is actuated. Subsequently, falling liquid level lowers the float, drawing the attraction sleeve into the magnetic field to activate the electrical or pneumatic switch (signaling liquid absence).FallingRisingRising LevelWhen the float is supported by liquid, the float and the mechanical linkage position the attraction sleeve down in theenclosing tube. Positioned at the bottom of the enclosing tube, the attraction sleeve is outside of the magnetic field generated by the external magnet. When the attraction sleeve is removed from the magnetic field, the magnetic field is disengaged. The bias spring snaps the external magnet away from the attraction sleeve. The switching element is deactuated.Verify that obstructions are not present in the application which would prevent free float or diaplacer movement throughout the entire range of motion. Assure that mounting provides vertical alignment of the switch. For proper operation, the unit must be mounted with the electrical housing and enclosing tube centerline within 3º of vertical. The conduit connection centerline must be within 3º of horizontal.Controls operating in liquids which tend to leave deposits in the piping shouldincorporate tee or cross type fitting to allow periodic cleaning of the process piping. A drain or blow-down valve will assist in cleaning the control chamber and piping.Insulation of the control chamber is acceptable, but temperature extensions, fi nned extensions and switch housing and cover must not be insulated.Not following these installation instructions, including pipe and valve diameter and pipe lengths can affect operation of the switch, includingdifferential. See Single Switch Chamber Installationand Multiple Switch Chamber Installation . Multiple Switch Chambers Pipe support hangers or stands should be used where necessary.All isolation valves must be fully open during service, as restricted valves may cause erroneous level switching. Single Switch Chamber In addition to the Single Switch installation instructions, multiple chamber installations have the following requirements:Headers connecting multiple chambers to the process connectionmust be larger than the chamber process connection diameter to allow adequate liquid flow to all chambers. Multiple chamber diameters are listed below:- two chambers should be 1.5 times larger- three or four chamber installations should be 2 times larger- five or more chamber installations should be at least 2.5 times larger.Valves, tees, elbows and other pipe fittings in a header must be the same diameter as the recommended header diameter.External chamber piping should be short, straight and unrestricted. Pipe must be of a diameter equal to or greater than the process connection diameter.Valves and other equipment between the chamber and processmust be of the same diameter or larger than the process connection diameter to allow adequate liquid flow into the chamber.Locate switch chamber process connection 12” to 24” (300mm to 600mm) awayfrom the process pipe or tank.Locate the switch chamber so that the switch actuates or deactuates at the desiredlevel. Refer to catalog for set point information.For bottom chamber connections, connect the bottom chamber process connectionto the process pipe or tank 6” to 12” (150mm to 300mm) below the centerline of the chamber. For side chamber connections, pipe directly to the process pipe or tank. This will ensure liquid level in the switch chamber is as close as possible to process liquid level.Inside diameter of piping, including elbows, tees and valves, must be equal to orgreater than process connection diameter.One elbow is recommended to connect the level switch chamber with the processpipe or tank (if required).Deviating from any of these instructions may adversely affect operation of the level switch by restricting liquid flow into the switch chamber. The recommended dimensions allow adequate space for isolation valves, pipe fi ttings and insulation. Structural support (not shown) must be provided for level switch chambers.isolation valves, fi ttings and insulation. Structural support (not shown) must be provided for level switch chambers.The header pipe diameter for three (3) or four (4) chambers needs to be two timesthe process connection diameter. For 1” (25mm) process connections, the pipe header must be 2” (50mm) in diameter. This includes pipe connecting the header to the process, fittings, valves and other pipe equipment installed as part of the header piping. Headers should be arranged to use one elbow or tee to connect to the process pipe or tank.Pipe connecting the header to individual chambers can be the same size as theprocess connection on the switch chamber. Fittings and valve diameters must also be equal to or greater than the process connection diameter. One elbow is recommended to connect the level switch chamber to the header pipe.Install each chamber so that the actuate or deactuate point is at the desired processliquid level. Refer to catalog for set point locations.Locate the header 8” to 16” (200mm to 400mm) away from the process tank. Locate switch chamber process connection 12” to 18” (300mm to 450mm) awayfrom the header pipe.Horizontal spacing of level switch chambers should be 6” to 12” (150mm to 300mm).NOTE: For ATEX or IEC Certifi ed T6 and S3 Enclosures: Electrical conduit connection threads may be of non-ISO thread form. Check the product certifi cation nameplate for relevant thread form information before attempting to connect to the electrical conduit connection. In the event a fi tting or adaptor is used, check the adaptor body for thread form information. The cable entry device shall be certifi ed under explosion protection type “d” for fl ameproof enclosures, suitable for the conditions of use if correctly installed.NOTE: For Product Utilizing a Hermetically Sealed Switch. If the unit is installed in a Class I, Div. 2 location, a conduit seal is not required per the National Electric Code (NEC) 501.5B.Ensure that the wiring conforms to all applicable local and national electrical codes and install unit(s) according to relevant national and local safety codes. Switch housing conduit connections may be rotated 360° by loosening the set screw located under the housing base. Do not attempt to rotate without following this instruction and loosening the set screw. Retighten the set screw after adjusting the housing. Care must be taken in positioning the incoming wiring to ensure clearance between the wiring and the switch housing. Switch wiring should be brought through the conduit connection, under the baffle plate, wrapped around the sealing tube and brought up to the proper terminal. All excess wire should be cut off prior to stripping the wire to avoid interference with the action of the switch mechanism or housing cover. All housings must be properly “sealed” at the conduit connection to maintain the NEMA classification. Check the housing cover-to-base fit to ensure the gaskets are sealed properly.Electrical power must be disconnected from explosion proof models before the cover is removed. Failure to do so could result in severe personal injury and/or substantial property damage.123Float PositionSPDT MechanismDPDT MechanismSOR Control DevicesSOR Control Devices456123461231235SOR Control DevicesSOR Control DevicesFloat PositionSPDT MechanismDPDT Mechanism123123123123456456VerticalHorizontalRising level set point is the level at which actuation occurs.

Top Mount Wide Differential Displacer Type – Differential may be adjusted by moving displacers up or down on the suspension cable. Set points are factory adjusted for the centerline of each displacer.Do not change factory-set switching element positions during installation. Pneumatic switches may be piped according to the charts below so that an air signal (outlet) is generated at either a high- or low-level condition.NOTE: Pneumatic switches must be used with clean, dry air or gas. All switches include apre-wired terminal block. These switches have higher current ratings for SPDT than DPDT. Preventive MaintenancePeriodic inspections are necessary to keep the switch in good working order. SOR recommends a systematic program of preventive maintenance be implemented at the time of installation. The following precautions are important and will help keep your switch in top operating condition. Keep the switching mechanism clean. Never leave the cover off longer than absolutely necessary. There is no need to lubricate any part of the switch.Inspect switches and wiring monthly. Dry contact switches should be inspected for excessive wear and misalignment. Pneumatic switch connections and tubing should be inspected for cracks and air leakage. Repair or replace as required.Do not operate switches that are defective or malfunctioning. When replacing parts, refer to Replacement Instructions supplied with the parts and follow instructioncarefully. When in doubt, contact the factory or the SOR representative in your area.Is the control being operated within the nameplate limitations? Is power connected to the control? Is the power “On”?Is the controlled equipment functional and wired properly? Is the level control wired properly? (See wiring continuity diagrams on Page 11 for proper wiring arrangement.) Is the control piped properly? The control must be piped so that it is within: a. - 3° of the horizontal centerline for horizontal mount units. b. - 3° of the vertical centerline for vertical mount units. c. Ensure that all process piping is free of foreign material and that isolation valves are fully open. d. Pneumatic lines must be free of liquid and foreign matter.Has the factory-set position of the switching element(s) changed?Is the control damaged? Inspect for cracks, terminal corrosion or lead wire damage. Replace the control if any damage is discovered.Does the control function when manually operated? Dry Contact Switches: Be certain the dry contact switch actuation lever is not bent, and the calibration set screw is positioned in the center of the lever. Manually move the magnet carriage. The carriage must not bind as it is moved. This manual movement of the carriage should cause switch actuation.* Make sure that the interior of the switch is free of dirt, corrosion and scale. Check the: a. Inside of the enclosing tube. b. Attraction sleeve and stem. c. Float or displacer. d. Interior of the chamber and process connections.* Ensure the factory-calibrated jam nut settings have not been moved and are carrying the attraction sleeve in and out of the magnetic field.Call the factory or the SOR representative in your area if inspection doesn’t reveal the problem.*NOTE: The enclosing tube gasket must be replaced each time the seal is broken. Standard gasket P/N 3070-015, spiral wound gasket P/N 3070-014 (for high pressure, high temperature and NACE units).SOR switches are designed for long life and trouble-free operation. However, should you suspect a malfunction, conduct the following inspection.Do not open when an explosive gas atmosphere may be present.If required, this product must be installed with an explosion proof breather vent or drain per Agency requirements and the National Electric Code –Article 501, Section F, paragraph 3.For ATEX Certifi ed ModelsSOR ® agrees to repair or replace any switch found to be defective in material or workmanship within five years from date of shipment.

SOR超声波液位开关样本

无（或很少）气泡－特别是对于粘度大于 100cP（30W 机油）的液体。在粘稠液体中的较大气泡会阻挡声波信号的传播，使其不能穿越凹槽。低粘度的液体中可以允许存在相对大量的气泡，因为这种气泡通常是非常小（如将阿斯匹林溶于水中）。
如果这些应用原则得到了正确地遵守，则超声波液位开关能够提供免维护的工作性能，并且不需要进行任何校准工作或定期调整。
超声波液位开关利用了超声波在空气和液体中的传播特性来检测液体的液位。即声波在空气中进行传播时，其信号强度出现很大的损失。而当声波在液体中进行传播时，其信号强度几乎保持不变。
为了达到检测液体液位的目的，我们必须确定在凹糟内是否存在液体或气体（空气）。由于液体的密度高于气体，所以通过液体传播声波时更为容易。凹槽一侧的传感器发射声波，而另一侧的传感器对声波进行检测。在凹槽中存在液体时，在检测侧所接收到的声波量很大。而当凹槽内存在气体（空气）时，检测侧只能接收到少量的声波。电子电路可以检测这种声波量的不同，并相应地输出继电器开关信号。

超声波开关
工作原理
超声波开关中包括了两个压电晶体，一个压电晶体发射声波，而另一个压电晶体接收声波。两个压电晶体分别安装在金属材质传感器的凹槽两侧。发射晶体产生高频率的声波（1MHz 至 3MHz），这束超声波直接通过凹糟传播至接收晶体。接收晶体将所接收到的声波能量转换成电信号，这个电信号经过电子电路的处理后，就可以确定凹糟内存在液体还是存在空气。

超声波开关
应用范围
超声波开关的应用和使用均十分简便，它的应用范围只有很少的几项限制：介质必须是液体工艺温度在－40 至 250℉（－40 至 121℃）之间介质中的悬浮固体成分必须小于 5% 对于粘度为 100cP（30W 机油）以上的液体，不得曝气
只适用于液体－工艺介质必须是液体。超声波液位开关无法区别出两种气体之间或者气体与固体之间的差别。而要达到正确的检测，则要求液体的密度是均匀的。
只适用于清洁的液体－液体中固体含量过高时，液体对声波的传播程度就不能满足进行检测的要求。典型情况下，液体中最大允许悬浮固体量为 5%。
液体必须是流动液体－在液体无法排出传感器凹槽的应用条件下，会造成虚假报警。如果液体的粘度过大，以至于无法流出传感器的 3/4 英寸的凹槽，则传感器无法正常工作。在某些情况下，这一点可以通过不同的安装型式予以解决，但当某些液体的粘度实在太大，则不能进行使用。

为什么有时要倾向于采用超声波开关，而不是其它料位检测技术呢？这要取决于用户的应用情况，也许在某种情况下，3 种或 4 种技术同样适用，但是在考虑了各项技术的特色和优点后，只有一种才是最佳的选择。采用超声波开关是一种经济合理的解决方案。这套装置要求将探头（以螺纹连接或法兰连接方式）安装在容器上，接好电源和控制接线，就可以通电使用了。它不需要其它设置或校准操作步骤。由于超声波开关是一种没有活动部件的电子仪表，所以其预防性维护只需每年进行一次目视检查即可。唯一的推荐备件是“电路板”，而且每 10 台开关只备一块电路板即可。开关的维护工作可由具备基本电气技术（接线）的技术人员即可胜任。
