These instructions provide information for installation, electrical connection, process connection and calibration of 107 Differential Pressure Switches.107Differential Pressure Switch Process pressure is sensed by a diaphragm and piston assembly. The piston responds to differential pressure and moves a shaft that actuates (deactuates) an electrical switching element. Low side pressure and a wetted adjustable range springoppose high side pressure. Calibration is accomplished by adjusting the range spring with the set point adjustment screw.Design and specifications are subject to change without notice.For latest revision, go to NOTE: If you suspect that a product is defective, contact the factory or the SOR ® Representative in your area for a returnauthorization number (RMA).

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.

1. 差压变送器原理压力和差压变送器作为过程控制系统的检测变换部分，将液体、气体或蒸汽的差压(压力)、流量、液位等工艺参数转换成统一的标准信号(如DC4mA～20mA 电流)，作为显示仪表、运算器和调节器的输入信号，以实现生产过程的连续检测和自动控制。
差动电容式压力变送器由测量部分和转换放大电路组成，如图1.1所示。
图1.1 测量转换电路图1.2 差动电容结构差动电容式压力变送器的测量部分常采用差动电容结构，如图1.2所示。
中心可动极板与两侧固定极板构成两个平面型电容H C和L C。
可动极板与两侧固定极板形成两个感压腔室，介质压力是通过两个腔室中的填充液作用到中心可动极板。
一般采用硅油等理想液体作为填充液，被测介质大多为气体或液体。
隔离膜片的作用既传递压力，又避免电容极板受损。
当正负压力(差压)由正负压导压口加到膜盒两边的隔离膜片上时，通过腔室内硅油液体传递到中心测量膜片上，中心感压膜片产生位移，使可动极板和左右两个极板之间的间距不相对，形成差动电容，若不考虑边缘电场影响，该差动电容可看作平板电容。
差动电容的相对变化值与被测压力成正比，与填充液的介电常数无关，从原理上消除了介电常数的变化给测量带来的误差。
2. 变送器的使用（1）表压压力变送器的方向低压侧压力口（大气压参考端）位于表压压力变送器的脖颈处，在电子外壳的后面。
此压力口的通道位于外壳和压力传感器之间，在变送器上360°环绕。
保持通道的畅通，包括但不限于由于安装变送器时产生的喷漆，灰尘和润滑脂，以至于保证过程通畅。
图1.3为低压侧压力口。
图1.3 低压侧压力口（2）电气接线①拆下标记“FIELD TERMINALS”电子外壳。
②将正极导线接到“PWR/COMN”接线端子上，负极导线接到“-”接线端子上。
注意不得将带电信号线与测试端子（test）相连，因通电将损坏测试线路中的测试二极管。
