SOR Inc. 107 差分压力开关安装说明书

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).

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.

施耐德电气 CS 压力开关-手册说明书

CS pressure switches have a built-in pressure operated, three-pole switch. The contact position of which depends on the pressure in the connector and the range setting and adjustable differential.The pressure switches are fitted with a manual switch that will lock the contact system in the open position independently of the pressure in the system. Pressure switches with relief valve is used in compressed air systems where pressure relief on the compressor piston before start is required.The CS is suited for automatic start and stop of air compressors and water boosters.Features:•Pressure ranges 2 – 20 bar•Pressure connection G ½ or G ¼•Contact system 3-pole (TPST) as standard available also as an accessory •Adjustable differential •Relief valve as accessory•Manual switch to lock the contact system •Enclosure IP43 or IP55•Special versions with pressure connection made of polyacetal suitable in drinking waterapplications1 2 3 4 5 6 7 8 910111213141516171819202122232425FunctionFigure 1: Design and function Danfoss31E58Slide ringEarth screw Cover screw CoverSpindleToggle armSnap springSnap armSwitch housing assy Self-tapping screwManual switchBaseGrubscrewStop pressure screwPressure padSpring retainerCompression springPressure shoeDiaphragmFlange, G ¼ or G ½CapDifferential armTension springDifferential pressure screwBracketThe pressure switch is built up of the following main elements: connector, diaphragm, snap system, main spring, differential spring and a 3-pole or one-pole contact system. The stop pressure must be set on the main spring and the difference between start and stop pressures on the differential spring.Pressure from the controlled system is led, via the connector, to the diaphragm. The diaphragm converts this pressure to a mechanical movement which is transferred by the snap system to the contact system. In this way, the contact system starts or stops a compressor/pump.Pressure switch, Type CSTechnical data(1)For water and seawater, max. 80 °C Figure 2: Resonance frequencySetting1.2.3.Figure 5: Installation Figure 6: Installationd > 8.5 mm – 1d ≤ 8.5 mm – 2031E0293turns, i.e. 4.5.InstallationRecommended orientationThe pressure switches will operate regardless of their orientation.

SOR开关说明书

∙SOR液位开关使用说明书∙SOR液位开关使用说明书SOR液位开关基本原理上升的液面将浮球或弹簧提升式沉筒浮起，带动磁力短管上升至磁场区，吸引并触发电路或气路开关（发出液位到达信号）。

液面下降时，次序相反，电路或气路开关被释开（发出液位下降信号）。

磁力滑块（通过密封套筒）将永久磁铁和开关组件与过程液面隔离，避免磁铁腐蚀和磁力碎屑堆积。

磁力运动传输消除了由机械装置弯曲运动传输带来的疲劳，损坏及过早失效等问题。

磁力运动传输避免了因探杆型传感器引起的表面涂层问题。

在没有工厂允许的情况下，不要改变开关的原件和结构。

SOR液位开关沉筒式结构沉筒悬挂在弹簧平衡联动杆上，液面上升时，沉筒的有效重量因受浮力而减小，弹簧回缩拉起连杆，使磁力短管在密封套筒中上升。

磁力短管的向上运动是在外部永久磁铁产生的磁场内，磁力把外部磁铁吸向磁力短管，牢固地吸附在密封套筒上，此时，微动开关被触发。

液面下降时各次序相反，磁力短管下落至磁场外，复位弹簧将外部磁铁拽离密封套管，微动开关复位。

SOR液位开关浮球式结构浮球与一根机械连杆固定在一起，液面上升至浮球，浮力使连杆上升，磁力短管升入密封套筒中，磁力短管的向上运动是在外部永久磁铁产生的磁场内。

磁力把外部磁铁吸向磁力短管，牢固地吸附在密封套管上，此时，微动开关被触发。

液面下降时各次序相反。

磁力短管下落至磁场外，复位弹簧将外部磁铁拽离密封套筒，微动开关复位。

SOR液位开关引压口联接外浮筒接管应当平直且不受干扰，控制头与外浮筒垂直中心线在3℃内。

注意：顶装式控制头与容器法兰或短管安装成与容器的垂直或水平中心线不超过3℃。

（即：外浮筒式与顶装式均应垂直安装）接管长度应控制在最小，以使开关整体更稳定。

如有需要，应采用接管悬挂或支承装置。

控制机构在液体中动作，接管中很可能堆积沉淀物，应采用“T”形或“+”形管接头，允许定期清洗接管。

排污阀及吹扫阀可用于清洁外浮筒和接管。

正常运行中，所有接管上阀门应完全打开，因为限流可能导致误动作。

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.

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.

Adjustable Dead Band Pressure SwitchesThe adjustable dead bandpressure switch should be used when there is a requirement for an adjustable and wide dead band between the increasing and decreasing set points.FunctionAlarm: Hi — Lo Control: On — OffV1 Weathertight HousingDesign and specifications are subject to change without notice.For latest revision, see .V3 Weathertight Explosion ProofHermetically Sealed SwitchesSEE MORE AT Request QuoteThe SOR Adjustable Dead Band pressure switch incorporates two industry proven Static “O” Ring pressure sensing elements. Media pressure on the areas of the pistons counteracts the forces of the range springs — each adjustable by a separate adjusting nut — and moves the piston shafts to operate the lever assembly which, in turn, actuates and deactuates the electrical switching element. Each pressure sensing element of the Adjustable Dead Band pressure switch is a force balance piston-actuated assembly sealed by a flexible diaphragm and an o-ring that is static. The only wetted parts are the single pressure port, two diaphragms, and two o-rings all indicated with asterisks (*) in this illustration.Principles of OperationPressure SwitchesNo Pressure:Electrical switching element is deactuated.Pressure greater than decreasing Set Point but less than increasing Set Point.

CCS、SOR压力开关选型说明
例一、CCS选型
1. 符号含义及命名实例
型号的选择：
604系列是经济型，价格低,性能好。

6900系列是小型压力开关。

6600系列接线头向下,有利于防水。

型号后缀有"Z"者压力接头为不锈钢,适于频繁拆卸或腐蚀性较强的场合。

型号后缀有"P"者为"活塞"型压力开关,由于阻尼作用强,特别适合应用于被测介质压力波动比较厉害的
场合如:锅炉给水水泵的出口等。

具体说明如下：
6900，611--表示紧凑型
604，646--表示通用型
675，68xx--表示微压型
G--表示隔膜式压力开关
P--表示活塞式压力开关
D--表示隔膜式差压开关
V--表示真空
T--温度
U--带毛细管
E--带防爆功能
M--表示双刀双掷DPDT（无M表示单刀双掷SPDT）
Z--接口材料为不锈钢（无Z表示铝合金）
带尾缀-7011，7042表示隔膜材料为不锈钢
无尾缀表示隔膜材料为聚丁钠橡胶
举例：
1）型号：646GZEM-7011，表示通用加强型压力开关，接口材料为不锈钢，带防爆功能，DPDT开关，隔膜材料为不锈钢。
