For latest revision, see .Quick Selection Guide - VacuumPressure SwitchA bi-stable electromechanical device that actuates/deactuates one or more electrical switching element(s) at a predetermined discrete pressure/vacuum (Set Point) upon rising or falling pressure/vacuum.Adjustable RangeThe span of pressure between upper and lower limits within which the pressure switch can be adjusted to actuate/deactuate. 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. Whenoptional switching elements are speciﬁ ed,corresponding dead band multipliers shownon pages 8 and 10 must be applied.2. The 12/66 piston/spring combination isavailable with the N switching element only.3. Adjustable range becomes 10 to 45 in. wcwhenever switching elements other than K, KA,W or D are used.4. Special ranges may be possible. Consult thefactory or the SOR representative in your area. 5. Diaphragms may have an additional effect ondead band. See page 13, Note 9.6. Diaphragm life may be limited by using T or Hswitching elements with Numbers 1 and9pistons.7. Metric bar (mbar) values are practicalequivalents of the reference English values; notnecessarily exact mathematical conversions.This data appears on the product nameplatewhen metric engineering units are speciﬁ ed.8. A breather drain (Accessory KK, see page 16)should be speciﬁ ed when low pressureadjustable ranges are used in environmentswith signiﬁ cant ambient temperature changes.9. Filled isolators attached to the pressure switchwill affect dead band.This table is a listing of piston–spring combinations and the corresponding adjustable ranges, dead bands, overrange and proof pressures. SOR vacuum switches are compound; they will operate in either vacuum or pressure modes. Adjustable range is expressed from maximum vacuum decreasing to zero gauge andincreasing to maximum pressure. Dead band is expressed as typical. See dead band considerations below. The Set Point must be within the adjustable range. A vacuum switch is generally better suited than a pressure switch for Set Points very near zero gauge.Notes1. Dead band values are expressed as typical expected at mid-range with the standard K switching element assembly installed. When optional switching elements are speciﬁ ed, corresponding dead band multipliers shown below must be applied.2. Special ranges may be possible. Consult the factory or the SOR representative in your area.3. Diaphragms may have an additional effect on dead band. See page 13, Note 9.4. Metric bar (mbar) values are practical equivalents of the reference English values; not necessarily exact mathematical conversions. This data appears on the product nameplate when metric engineering units are speciﬁ ed.1. Dead band values are expressed as typical expected atmid-adjustable range using the standard K switching element. When optional switching elements are speciﬁ ed, corresponding dead band multipliers must be applied.2. Dead bands are ﬁ xed (non-adjustable), except when T or H switching elements are used.3. Dead band can be adjustable by selecting T or H switching element. (Diaphragm life may be limited when used with Numbers 1 and 9 pistons.)4. Dead band multipliers must be applied to the typical dead band value shown for piston-spring combination in speciﬁ cations, pages 7 and 8, whenever optional switching elements other than K, KA or W are used.5. Dead band can be widened by selecting an optional switching element with a multiplier greater than 1.0. Example: Model 6NN-G5-M4-C2A-YY Typical Dead Band 1.4 psi G-Switching Element multiplier = 3 Corrected Typical Dead Band 1.4 x 3 = 4.2 psi6.

Available in 1/2” NPT and 3/4” NPT process connections in brass or 316 SS.Thermal WellJam nuts provided with thermal wells.11Switch Unit – ASCO uses the term “switch unit ” to describe the electromechanical portion of a pressure or temperature switch. This is used in conjunction with a transducer unit to form a complete pressure or temperature switch.Transducer Unit – ASCO uses the term “transducer unit ” to describe that portion of a pressure or temperature switch to which a pressure or temperature is applied which converts the input signal to another form of energy to operate the switch unit.Two-Stage (Dual)– ASCO uses the term “two stage ” todescribe a pressure or temperature switch which is equivalent to two pressure or temperature switches which are independently adjustable. This switch is equivalent to two fixed deadband switches.Deadbands – The deadband is the difference between the set point and reset point readings. Deadbands are listed in the specification tables at nominal values. They are representative of the deadbands of the units at the middle of the range.The deadband values for the full range adjustable deadband switches and limited adjustable deadband switches indicate the values through which the deadband may be adjusted.Generally, as the set point is adjusted through the operating range, the deadband will vary. Normally, it will becomenarrower as the set point is towards the bottom of the range,and will become wider when the set point is towards the top of the range. The graph shown below indicates representative trends of this type of deadband variation.Temperature switch deadbands are a result of the characteris-tics of the vapor pressure curve as well as other factors.Normally, this results in a deadband which is narrower in the top third of the range than in the bottom third of the range.The values published are nominal and representative of mid-range set points.36Accuracy – The maximum deviation from the set point under specified operating condition (ambient temperature,barometric pressure, etc.).Adjustable Deadband – Refers to the capability of apressure or temperature switch to allow the deadband to be adjusted over a given range. Certain ASCO TRI-POINT switches have an adjustable deadband which can be adjusted over the total operating range of the switch.Adjustable Operating Range – The pressure or tempera-ture range of the switch within which the set point may be adjusted.Differential Pressure – The difference between twopressures. A differential pressure switch senses two pressure sources and can be adjusted to actuate on a desired difference between them.Guage Pressure – The actual reading of a typical pressure guage and is the difference between the pressure within a vessel and the atmospheric pressure surrounding it. It is normally measured in pounds per square inch (psig).Manual Reset – The switch is a semi-automatic device which operates automatically with a signal change in one direction but must be manually reset once the signal returns to its original position.Proof Pressure – A pressure which a device can besubjected to for extended periods of time without changes in its operating characteristics.Rated Overrange Temperature – A temperature which a device can be subjected to for extended periods of time without changes in its operating characteristics.Repeatability – The closeness of agreement among a number of consecutive measurements of the output for the same value of input under the same operating conditions approaching from the same direction. Repeatability isnormally specified as a percentage of the upper limit of the operating range.Example: Operating range 5-100 psig with +1%repeatability; equals +1% of 100 psig or +1 psig.Reset Point – After a pressure or temperature switch has reached its set point and operated the electrical switch, it must return to a point called the reset point before the electrical switch can return to its original position.Set Point – The pressure reading at which the electrical switch element changes contact position (it can be specified either increasing or decreasing).DefinitionsDeadbands1.5 x Catalog Value Catalog Value Half Catalog ValueBottom Mid TopPosition of Set Point in Range37These recommendations are to be used as a guide only, as service life of material is dependent on temperature, concentrations, or catalysts that may be added and other conditions which are beyond our control.Consult ASCO for specific service applications.Note:Items in black circles are standard catalog units.All others available on factory order.P - Indicates preferred construction.

3S压力开关上RANGE和 DIFF是什么意思

3S压力开关上RANGE和 DIFF是什么意思？发布时间：11-09-09 来源：上海杉幸通用件有限公司点击量：12000 字段选择：大中小3S压力开关上RANGE和 DIFF是什么意思？RANGE就是压力的量程范围。

DIFF就是pressure difference，指的是切换差，也就是死区，是一个切换区域。

每个压力开关都有这个参数，只不过有些压力开关的死区是可调的，而更多的压力开关死区是不可调的。

根据压力开关的不同，其设定值可能是上切换值或下切换值或上下都不是，因此都压力开关需要调节。

你可以试一下，当设定值为1 6bar，切换值为2bar时，如果压力由0升到17bar时动作，那么设定值就是上切换值；当设定值为16bar，切换值为2bar时，如果压力由17bar以上降到15bar时断开，那么设定值就是下切换值；当设定值为16bar，切换值为2bar时，如果压力开关不在15bar或17ba r时动作，那么上下都不是。

其实，设定值是什么切换值不要紧，下面介绍一个通用的设定方法。

切换差不可调控制器设定值调整步骤，举例说明如下：举例：选用设定范围在0.05-2.5MPa的控制器，要求压力升至2.0MP a(此值为上切换值）发出触点信号。

1. 松开锁紧器，将控制器旋入校验台的螺纹接口上；打开盖板，将电缆穿过电缆接口接入端子板，电缆另一头接上万用表；2. 加压至2.0MPa,此值可由标准压力表读出；顺时针转动设定值调节镙杆，使设定值由大变小，直至微动开关在2.0MPa处切换。

3. 旋动锁紧器，调节校验台压力，使其在2.0MPa上下来回变化，校验压力上升时，切换值是否为2.0MPa，此值即为要求设定的上切换值，此值减去切换差（约0.085MPa)即为下切换值。

举例：同样选用设定范围在0.05-2.5的控制器，但要求压力下降至1.8MPa(此值为下切换值）发出触点信号。

1. 松开锁紧器，将控制器旋入校验台的螺纹接口上；打开盖板，将电缆穿过电缆接口接入端子板，电缆另一头接上万用表；2. 加压至1.8MPa,此值可由标准压力表读出；逆时针转动设定值调节镙杆，使设定值由小变大，直至微动开关在1。

sor压力开关工作原理

sor压力开关工作原理
Sor压力开关（也称为静压力开关）是一种用于监测液体或气体压力的开关装置。

它的工作原理基于压力的变化来控制电气电路的开闭。

当压力施加在Sor压力开关上时，内部的感应元件（通常是一个弹簧或膜片）会受到压力的影响而发生形变。

这种形变会导致感应元件内部的接点发生移动，从而改变开关的状态。

当压力达到设定值时，开关会闭合或打开，从而触发相应的电气信号。

Sor压力开关通常用于控制液体或气体系统中的压力，以确保系统在安全范围内运行。

例如，当压力超过设定值时，Sor压力开关可以自动切断供应液体或气体的流动，以防止系统过载或损坏。

它还可以用于监测液体或气体的压力变化，并触发相应的报警或控制信号。

总的来说，Sor压力开关的工作原理是基于压力的变化来控制内部接点的状态，从而实现对液体或气体压力的监测和控制。

这种设备在工业自动化和流体控制系统中起着重要作用，保障了系统的安全运行和稳定性。

Analogue outputMenu for basic settings (adapting the EDS 300 to the particular application) Two different types of programming enable Three different output models are available:EDS 300 with 1 switching output (1.2 A load capacity, no analogue output) EDS 300 with 2 switching outputs (1.2 A load capacity, no analogue output)EDS 300 with 1 switching output (1.2 A load capacity) and 1 analogue output (4...20 mA)2. MountingThe EDS 300 can be mounted directly onto a hydraulic block via the pressure connection (7/16 SAE 4 female).When used in critical applications (e.g. strong vibrations or knocks) the pressure connection must be mechanically decoupled via a Minimess hose. Mounting clamps are available as an accessory (see point 12.2 "Accessories - for mechanical connection").The electrical connection should be carried out by a qualified electrician according to the relevant regulations of the country concerned (VDE 0100 in Germany). The pressure switch housing must be earthed properly at the same time. When fitted into a hydraulic block it is sufficient if the block is earthed via the hydraulic system. In the case of Minimess hose-mounting, the housing must be earthed separately.Additional assembly notes which, from experience, reduce the effect of electromagnetic interference:Make line connections as short as possible. Use screened lines (e.g. LIYCY 4 x 0.5 mm 2)The cable screening must be fitted by qualified personnel subject to the ambient conditions and with the aim of suppressing interference.Direct proximity to connecting lines of user units or electrical or electronic units causing interference must be avoided as far as possible.3.Operating keys on the membrane keypad4-digitkeys for setting switchingdigital displayadditional functionspoints, switch-back points and e s y o f C M A /F l o d y n e /H y d r a d y n e ▪ M o t i o n C o n t r o l ▪ H y d r a u l i c ▪ P n e u m a t i c ▪ E l e c t r i c a l ▪ M e c h a n i c a l ▪ (800) 426-5480 ▪ w w w .c m a f h .c o mAfter switching on the supply voltage, the unit briefly displays EdS followed by the current pressure.In the basic settings the display can be altered.

The following settings can be made under the basic setting:5.1.1Switching point setting (SP)One switching point and one hysteresis can be set for each switching output. The respective output switches when the pre-set switching point is reached and switches back when the pressure falls below the switch-back point. The switch-back point is determined by the pre-set hysteresis (switch-back point = switching point minus hysteresis).Abbreviations:"S.P.1", "S.P.2" =switching point 1 or 2"h.Y.1", "h.Y.2" = hysteresis 1 or 25.1.2 Window function setting (WIN)The window function enables a range to be monitored. For each switching output, in each case an upper and a lower switching value can be input which determine the range.The respective output switches when the pressure enters this range. Upon leaving the range, i.e. when the switch-back value has been reached, the output switches back. The lower switch-back value is just below the lower switching value (lower switching value minus three times the increment, see point 5.4). The upper switch-back value is just above the upper switching value (upper switching value plus three times the increment, see point 5.4).The area between switching and switch-back value forms a safety zone which prevents unwanted switching operations from occurring (e.g. triggered by pulsations from a pump).Example for switching output 1 (normally open function):Abbreviations:"hi.1", "hi.2"= Hi gh level 1 or 2 = upper switching value 1 or 2"Lo.1", "Lo.2"= Lo w level 1 or 2= lower switching value 1 or 2Note:The window function only operates correctly (switching on and off), when all switchingvalues (including the safety zone) are greater than 0 bar and lower than the nominal pressure range.5.2 Analogue outputhi.1 plus 3xincrementLo.1 minus 3xincrementPON OffSwitch-back valuet Switching valueSwitch-back value Switching value hi.1e s y of C M A /F l o d y n e /H y d r a d y n e ▪ M o t i o n C o n t r o l ▪ H y d r a u l i c ▪ P n e u m a t i c ▪ E l e c t r i c a l ▪ M e c h a n i c a l ▪ (800) 426-5480 ▪ w w w .c m a f h .c o mPress "mode" key"S.P.1" or "hi.1" is displayedKeep pressing the "mode" key until the required parameter is displayed (depending on the basic setting: "S.P.1", "h.Y.1", "S.P.2", "h.Y.2", "hi.1", "Lo.1", "hi.2" or "Lo.2").keys to alter the setting.keys.If no keys are pressed for 3 seconds, the display changes back and the settings are saved.pressure displaypress mode key displayuntil the required parameter isreached.Notes:If "LOC" appears in the display when trying to alter the settings, programming is disabled.Corrective action: set programming enable to "ON"(see point 7 "Programming enable")key is held down during alteration, the value automatically advances.

案例分享经验失灵低负荷吹灰负压波动触发锅炉MFT事件可以避免吗

案例分享：经验失灵，低负荷吹灰，负压波动，触发锅炉MFT事件，可以避免吗？【事件经过】2018年2月3日4:50，61 号机组负荷从570MW 降至360MW。

11:50，机组负荷365MW，A、B侧引风机、送风机、一次风机及A、B、D、F磨煤机行。

12:05，开始进行炉膛吹灰，12:28炉膛负压由-50Pa 突然上涨至500Pa后降至-500Pa，显示锅炉有较大垮灰现象，立即停止吹灰并投A2油枪稳燃，燃烧稳定后停运A2油枪。

12:50恢复吹灰，在炉膛出口折焰角上方A侧长吹灰器（L07）吹灰时，13:24：07发现火焰电视变暗，炉膛负压在﹢70Pa至-100Pa之间波动且有增大趋势，立即投入A2油枪稳燃，并进行吹灰器退出烟道的操作，操作过程中锅炉MFT动作跳机。

组织对机组进行全面检查，确认无异常后，14:45 锅炉重新点火，17:55机组重新并网。

【相关情况】1.设备基本情况61炉为DG1932.7/25.4-II8 型超临界参数、W型火焰燃烧、垂直管圈水冷壁变压直流锅炉、一次再热、平衡通风、露天布置、固态排渣、全钢构架、全悬吊结构Π型锅炉。

锅炉炉膛负压共3个测点，位于炉膛上部，标高60米，布置在A侧墙、B侧墙、前墙水平中部，对应炉膛压力低低低1、炉膛压力低低低2、炉膛压力低低低3压力开关，三取二延时3S后MFT保护动作。

锅炉火焰电视监视口位于燃烧器平台上方，标高约32米，安装在炉膛四角。

锅炉火焰检测探头位于燃烧器平台，标高约30米，在炉膛拱下。

2.锅炉吹灰有关情况说明为保证锅炉吹灰效果和燃烧稳定，锅炉厂技术中心2012年对电厂锅炉吹灰负荷和时间要求做出了建议，推荐450MW 及以上负荷时进行吹灰工作。

但由于电网需求原因，电厂机组长期在360MW 负荷运行，无法达到建议的吹灰负荷。

为解决由于长期低负荷无法吹灰，造成多次发生大量垮灰导致燃烧波动大的问题，电厂经过摸索，制定了锅炉低负荷吹灰方案，于2012年11月开始进行低负荷投油吹灰，随着方案的有效实施，经验的积累，为节约燃油，逐步优化到不投油吹灰。
