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.

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.

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。

Switching element minimum/maximumambient temperatures:-40 to 167o F (-40 to 75o C) AF, AG, EB,EF, EG, JB,JF, JG, JR, KB -65 to 400o F (-54 to 204o C) B, Y, W-65 to 250o F (-54 to 120o C) A, E, J-65 to 180o F (-54 to 80o C) All others 6. Dead band multipliers must be applied to thetypical dead band figures given in thespecification tables on page 8.7. Switching elements B, W and Y have anElgiloy spring. Experience indicates goodservice in atmospheres with corrosivegases - H2S, ammonia, etc.CAUTION: The switching element assembly has been precisely positioned in the housing at the factory for optimum performance. Any inadver-tent movement or replacement in the field will degrade performance, could render the device inoperative and may void the warranty unless factory authorized procedures are followed.Differential Pressure SwitchAdjustable Range101NN-K 3-N4-C1A-YYThis table lists designators for corresponding adjustable ranges, dead bands, maximum system pressure and maximum differential pressure. Adjustable range is expressed for increasing pressure: the Set Point must be within the adjustable range. Dead band is expressed as typical at mid-range. See dead band considerations at the bottom of this page.Notes1. Ambient temperature range: -30 to 180o F (-34 to 80o C). Check restrictions, page 7, for optional electrical switching elements and page 9 for optional diaphragm systems.2. Metric bar (mbar) values are practical equivalents of the mathematical conversions. This data appears on the product nameplate when metric engineering units are specified.3. CAUTION: When the process could be considered dirty in terms of suspended particles, it is recommended that 20-micron in-line filters be installed on the Hi and Lo pressure ports.4. To achieve optimum performance, the 101/121 should be calibrated under simulated system operating conditions.Dead Band Considerations1. Dead band values are expressed as typical expected at mid-adjustable range and 50% maximum system pressure (static pressure) using the standard K switching element.2. Dead bands are fixed (non-adjustable), except when T or H switching elements are used.3. A dead band multiplier must be applied to the typical dead band value shown in adjustable range above whenever an optional switching element is specified.4. Dead band can be widened by selecting an optional switching element with a multiplier greater than 1.0.5. Use of metal diaphragms may have additional impact on Dead band values. Contact thefactory for details.Differential Pressure SwitchExample: Model 101NN-G3-N4-C1ATypical Dead Band 0.7 psid G-Switching Element muliplier 2 Corrected Typical Dead Band0.7 x 2 = 1.4 psidDiaphragm & O-Ring101NN-K3-N4-C1A-YY Notes1. N4 diaphragm system is standard. It isnormally suitable for air, oil, water andnon-corrosive processes.2. Other diaphragm and o-ring combinationsmay be available. Consult the factory or the SOR representative in your area for more information.3. Wetted parts have been selected asrepresenting the most suitable commercially available material for use in the serviceintended. However, they do not constitute a guarantee against corrosion or permeation, since processes vary from plant to plant and concentration of harmful fluids, gases orsolids vary from time to time in a givenprocess. Empirical experience by usersshould be the final guide. Alternate materials based on this are generally available.4. Differential pressures exceeding 100 psidmay affect Set Point when M2, M4, or H4diaphragm and o-ring combination is used. 5. Dead bands are higher when using metaldiaphragm options. Consult the factory.6. This table shows allowable minimum andmaximum temperatures for o-rings.Step 5: Pressure Port101NN-K3-N4-C1A-YYNotes1. C1A pressure port is standard. It is normallysuitable for air, oil, water and non-corrosive processes.2. Other pressure port materials and connectionsizes may be available.

This glossary applies to SOR Pressure Switches.Adjustable RangeThe span of pressure between upper and lower limits within which the pressure switch may be adjusted to actuate/deactuate. It is expressed for increasing differential pressure.Dead BandThe difference in pressure between the increasing Set Point and the decreasing Set Point. It is expressed as “typical,” which is an average with the increasing Set Point at mid- adjustable range for a pressure switch with the standard K switching element. It is normally fixed (nonadjustable).Differential Pressure SwitchA bi-stable electromechanical device that actuates/deactuates one or more electrical switching element(s) at a predetermined discrete differential pressure (Set Point) upon rising or falling differential pressure.DPDT Switching ElementDPDT is two synchronized SPDT switching elements that 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 field adjustable. Synchronization is verified by connecting test lamps to the switching elements and observing them go “On” simultaneously at actuation and “Off” simultaneously at deactuationHermetically SealedA welded steel capsule with glass-to-metal, factory-sealed, electrical leads that isolatesthe electrical switching element(s) from the environment.Maximum Differential PressureThe maximum difference in pressure that may be continuously applied between the Hi and Lo (Lo and Hi) pressure ports without causing permanent change of Set Point, leakage or material failure.OverrangeThe maximum input pressure that may be continuously applied to the pressure switch without causing permanent change of Set Point, leakage or material failure.Proof PressureThe maximum input pressure that may 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 profile. The closeness of the measured Set Point values is normally expressed as a percentage of full scale (maximum adjustable range 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 differential pressure. SPDT Switching ElementSingle-Pole, Double Throw (SPDT) has three connections: C — Common, NO — Normally Open and NC — Normally Closed, which allows the switching element to be electrically connected to the circuit in either NO or NC state.Glossary of T ermsDifferential Pressure Switch6.40.25 MIN TO 76.23.00 MAX3/4 NPT(F)(STD)1/2 NPT(F)(OPT)7.10.281/4 NPT(F) HI SIDE1/4 NPT(F) LO SIDEDimensions in this catalog are for reference only.

Sor压力开关设定
Sor压力开关设定、调试步骤
具体内容，请参考工厂英文版操作手册，如两者内容有出入，以英文版为准。
在校验设定值时，在常压压状态下将压力开关引压口与压力台相应管道对接，要求压力系统必须有压力表等似可以实时观察压力数据的装置。
然后给系统缓慢增压，要求系统增压最高压力不得超过压力开关铭牌上标定的over range值。
当压力值处于量程范围（adjustable range）时，可进行压力开关设定。
设定压力开关时，将开关单元外壳面板打开，用扳手按照压力值得高低旋转设定螺栓即可。
如图
使设定螺栓和刻度盘的对应压力值对齐即可。
压力开关设定完毕，即可安装使用。
将压力开关引压口安装到管道上，信号线由开关单元接出，根据需要连接到控制是或者相关的控制管道上。
接线时，需严格按照说明书进行操作。
如图：
通常情况下，下降报警时接常闭（C-NC）,上声报警接常开（C-NO）。
如果实际使用中发现信号反转，将接线NC与NO对调即可。
