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.

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.

NOTE: For 24 VDC operation (factory prepared), connect +24 VDC to TBB7 and 24 VDC return to TBB8. For 115 VAC or 230 VAC operation, there is no polarity.NOTE: Connect ground wire to the ground screw located in back of instrument enclosure. A ground wire must be attached to the ground screw located inside and on the back of instrument head for proper operation.n Remove the instrument head cover. Turn counterclockwise to expose the electronics.o Turn on power at its source.p Observe that either the red or green LED illuminates.q If neither lamp illuminates, refer to the troubleshootIng section.L.E.D. and Relay Status Logic (Fail-Safe)The L.E.D.s (L1-Red and L2-Green) are an indication of the sensor status (dry or wet) and are not affected by the position of the fail-safe jumper J-2. The fail-safe jumper J-2 changes the relay activation status allowing the user to select the fail-safe, power-off condition most appropriate to the application. Refer to and , showing the logic conditions between the sensors, L.E.D. lights, relay coil and contacts for each position of the fail-safe jumper J-2.Pre-Operational CheckIf the switch is installed and product level is below sensor level, or there is no flow, use the following procedure to verify preliminary operation.The switch comes configured from the factory with thefollowing operation with the J-2 jumper in the B position. (Seeg, page 7)Alternate Operation (Field Selectable), page 7)Red LEDThe switch comes configured from the factory with the following operation with the J-2 jumper in the B position. (See, page 9)Flow Sensor StatusFor optimum operation, calibration must be accomplished at actual process temperature and pressure conditions. Using as a location guide, adjust the system as follows:n Remove the instrument enclosure lid by turning it counterclockwise.o Apply power to the T21. Allow 5 minutes for the T21 to warm up. Verify J1 jumper is in the level position (Factory Default).p Ensure that the tank liquid level is below the probe sensor tips and the tips are dry.q Set the trip adjust potentiometer to zero fully counterclockwise (ccw).r Adjust the dry adjust pot so that the red LED just illuminates. This is a 25-turn pot. If the green LED is on, turn the pot counterclockwise (ccw). If Red LED is on, turn the pot clockwise (cw).s Toggle the dry adjust pot back and forth until the switching point is well defined.Leave the red LED illuminated. To ensure best definition/performance, waitapproximately 30 seconds between toggles.t Raise the level of the liquid to be detected until the probe/sensor tips are submerged and wet (covered).u Set the trip adjust pot to 100 (fully clockwise).v Adjust the wet adjust pot so that the green LED just does illuminate. This is a 25-turn pot. If the green LED is on, turn the pot clockwise.

Allow 5-minute warm-up. Verify J1 jumper is in low flow setting ifair/gas flow rate is approximately 20 f/s and below (factory default). For liquid or high air/gas flow rates, the jumper should be in high flow/level position.p Ensure that the pipeline is filled with fluid and at no or minimum flow.q Set trip adjust potentiometer to zero fully counterclockwise (ccw).r Adjust the no-flow pot so that red LED just illuminates. This is a 25-turn pot. If green LED ison, turn pot counterclockwise (ccw). If the red LED is on, turn the pot clockwise (cw).s Toggle no-flow pot back and forth until the switching point is well defined. Leave red LED illumi-nated. To ensure best definition/performance, wait approximately 30 seconds between toggles.t Adjust liquid or gas flow to maximum velocity. Ensure that flow is homogenous, constant and free of bubbles if a liquid.u Set trip adjust pot to 100 (fully clockwise).v Adjust the full-flow pot so the green LED just illuminates. This is a 25-turn pot. If green LEDis on, turn pot clockwise. If red LED is on, turn the pot counterclockwise.w Toggle full-flow pot back and forth until switching point is well defined. Leave green LED illuminated.To ensure best definition/performance, wait approximately 30 seconds between toggles. If the switch is to be used for flow - no flow, set the trip adjust pot to 50 and go to step 14. A more exact flow rate setting may be achieved by establishing flow at a desired rate with a separate flow meter and proceeding to step 13, to establish trip point.Adjust the trip adjust pot to obtain a trip as exhibited by a LED illumination. If a trip on decreasing flow is desired, set for red LED illumination.

Fluid vapor pressure changes predictably according to the influence of temperature on the sensing bulb. Process temperature changes cause proportional vapor pressurechanges in the temperature sensing bulb that act on the diaphragm/piston assembly to actuate and deactuate a snap-action electrical switching element at discrete process temperatures. The instrument’s behavior is determined by the vapor pressure principle.ElectromechanicalT emperature SwitchesForm 220The SOR ® ElectromechanicalT emperature SwitchT emperature Switches FeaturesVapor Pressure Principle● Device’s behavior is predictable andin accordance with the vapor pressure principle.● Minimal ambient temperature influence,fast response, high r epeatability, narrow dead band.Vapor Fill Fluid● Excellent chemical and thermalstability, predictable temperature-vapor pressure curve, nonflammable, lowtoxicity.Direct Immersion Temperature Sensing Bulbs● 316SS can withstand 2300 psig(1000 psig on 105 range) withoutthermowell; faster response time;lower cost.Remote Mount Sensing Bulbs● 316SS capillary tube with 300 Series SSarmor allows instrument to be panelmounted and bulb to be remotely located.● Standard 300 Series SS armor protectscapillary.Snap-Action Electrical Switching Element● Long life, high load capacity, high ambienttemperature limit, insensitive to vibration, SPDT or DPDT switching action,optional “hermetically sealed” capsulefor hazardous locations and hostileenvironments.Agency Listings/Certification● Select models with UL, CSA, ATEX, SAA. Factory Calibration● FREE!

(An optional remote temperature sensing bulb can be connected to the pressure port with an armor-clad capillary.) The temperature sensing system is partially filled with a fluid. Process temperature changes cause proportional vapor pressure changes in the temperature sensing bulb that act on the diaphragm/piston assembly to actuate and deactuate a snap-action electrical switching element at discrete process temperatures. The instrument’s behavior is determined by the vapor pressure principle. (The 105 range unit is similar, except the fill fluid is inert gas.)Dual (Hi-Lo)SOR temperature switches in this catalog may be specified with two Set Points. The two Set Points may be set at either the same actuation point or split up to full scale with no interaction between Set Points. The Dual Hi-Lo is available with hermetically sealed, explosion proof, UL Listed and CSA Certified electrical switching elements or with a wide selection of UL Listed and CSA Certified snap-action switching elements for both AC and DC service. The housing selection must be V1 or V2.

Adjustable RangeThe span of temperature between upper and lower limits within which the temperature switch can be adjusted to actuate/deactuate. It is expressed for increasing temperature.Set PointThat discrete temperature at which the temperature switch is adjusted to actuate/deactuate on rising or falling temperature. It must fall within the adjustable range and be called out as increasing or decreasing temperature.Dead BandThe difference in temperature between the increas-ing set point and decreasing set point. It is expressed as “typical,” which is an average with the increasing set point at mid-adjustable range with the standard K switch element. It is normally fixed (not adjustable). hermetically SealedA welded steel capsule with glass-to-metal, factory-sealed electrical leads that isolates the electrical switching element(s) from the environment. OverrangeOverrange temperature is that temperature to which the sensing bulb can be continuously exposed without causing permanent change of set point or distortion sufficient to cause leakage or significant degradation of the fill fluid. Temperatures greater than overrange could cause permanent damage and render the device inoperative.Maximum Process PressureThe maximum process pressure to which the temperature sensing bulb should be exposed without being protected by a thermowell.RepeatabilityThe ability of a temperature 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 consecutive cycles to establish a temperature profile. The closeness of the measured set point values is normally expressed as percentage of full scale (maximum adjustable range temperature.) Repeatability is 1% of full scale for ranges 135, 125 and 115. Range 105 has a repeatability of 2% of full scale.SPDT Switching ElementSingle-Pole, Double-Throw (SPDT) has three connections: C-Common, NO-Normally Open and NC-Normally Closed, which allows the switch 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 isnot 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 deactuation.SOR recognizes that there is not an industry convention with respect to terminology and definitions pertinent to temperature switches.

欧姆龙液位开关说明书
欧姆龙液位开关说明书-CAL-FENGHAI.-(YICAI)-Company One1开关液位设备概要选择机型的标准故障检查液位设备Q&A关于施工资料参考电极式液位开关（61F）作为电气性液位检测方式，被广泛用于以大厦、集中住宅的上下水道为主及钢铁、食品、化学、药品、半导体等各种工业、农业水、净水场、污水处理等的液面控制。
一旦电极接触到液体，通过液体可以闭合电路（电气流通的道路），根据流过的电流检知液位控制的动作原理，是以所谓的导电性液体为控制对象的液位开关。
进行检测时，直接检测液体的电极间电阻，根据大于或小于已设定的电阻值，来判断有无液面。
■基本原理以一般接收上水道供水的情况为例来进行说明。
通常，在大厦、集中住宅区等中，一旦接水槽接收供水后，就会将水送到设置在屋顶上的高架水槽内，然后再分配到各楼层。
在高架水槽内，如果因水的消耗而导致水槽内的水位下降，通过泵从接水槽中再进行补充。
达到一定的水位后，即可停止泵了。
（参照图1）在高架水槽内，可以进行水位的控制，以保持上限和下限间的水位。
可以根据下列工作原理来进行这一水位控制。
图1. 水槽的供水控制●根据水位对泵进行ON、OFF控制（2根电极式）①如图2，电极E1未接触到液面时，电流流通的电路（E1-E3间）为开路，没有电流通过。
因此，继电器「X」不动作，继电器「X」的接点仍为“b侧”。
②如图3，电极E1接触到液面时，为电路闭合状态（液体将E1-E3间闭合），因此，继电器「X」动作，接点移动到“a侧”。
若将该继电器接点连接到接触器，则可根据液面的位置对泵进行ON、OFF控制。
但是，如图2、图3，如果仅有2根电极，电极E1附近会发生波动，导致继电器抖动。
为此，电极式液位开关有自我保持电路。
（图2、图3用于水位的报警等方面）图2 水位低时图3 水位高时●带自我保持电路的实用性水位控制（3根电极式）如图4所示，使用E1、E3电极以外的E2电极，通过a2接点连接E2、E1。
