Its built-in toroidal sensor eliminates the inconvenience of installing a stand-alone current transformer. Includes onboard adjustments for current sensing mode, trip point, and trip delay. Detects over or undercurrent events like; locked rotor, loss of load, an open heater or lamp load, or proves an operation is taking place or has ended.For more information see:Appendix B, page 166, Figure 20 for dimensional drawing.Appendix C, page 169, Figure 17 for connection diagram.OperationInput voltage must be supplied at all times for proper operation. When a fault is sensed throughout the trip delay, the output relay is energized. When the currentreturns to the normal run condition or zero, the output and the delay are reset. If a fault is sensed and then corrected before the trip delay is completed, the relay will not energize and the trip delay is reset to zero.AdjustmentSelect the desired function, over or under current sensing. Set the trip point and trip delay to approximate settings. Apply power to the ECS and the monitored load. Turn adjustment and watch the LED. LED will light; turn slightly in opposite direction until LED is off. Adjustment can be done while connected to the control circuitry if the trip delay is set at maximum. To increase sensitivity, multiple turns may be made through the ECS’s toroidal sensor. The trip point range is divided by the number of turns through the toroidal sensor to create a new range. When using an external CT, select a 2VA, 0-5A output CT rated for the current to be monitored. Select ECS adjustment range 0. Pass one secondary wire lead through the ECS toroid and connect the secondary leads together.If desired part number is not listed, please call us to see if it is technically possible to build .NC = Normally Closed Contact A = Sensing Delay On Start Up TD = Trip DelayR = ResetOC = Monitored Cur rentAFFB9L; HLMU; SCR9LLLC4; LLC6; PLSECS; ECSWAppendix B - Dimensional DrawingsFIGURE 15FIGURE 16FIGURE 18DCSAFIGURE 22inches (millimeters)(ECS has spade connectors andECSW has terminal board)FIGURE 15 - HLV Series FIGURE 16 - KVM SeriesV = VoltageL = LEDS = Undervoltage SetpointNO = Normally OpenNC = Normally ClosedC = Common, Transfer ContactL1N/L2FIGURE 17 - ECS SeriesV = VoltageI> = OvercurrentI< = UndercurrentFIGURE 18 - ECSW SeriesMC = Motor ContactorM = MotorF = FusesOL = OverloadRSW = Reset SwitchPositiveSwitchingNegativeSwitchingSinkingSourcingFIGURE 19 - TCS SeriesFIGURE 20 - TCSA SeriesZ = Zero AdjustS = Span AdjustW = Insulated Wire Carrying Monitored CurrentPLC = PLC Analog Input or Meter InputAppendix C - Connection DiagramsW = Insulated WireCarrying Monitored CurrentRelay contacts are isolated .FSW = Fan or Float ContactsCR = Control RelayCS = Current SensorMCC = Motor Contactor CoilI> = Adjustable OvercurrentI< = Adjustable UndercurrentW = Monitored Wire∆T - Adjustable Trip DelayL = LoadV = VoltagePS = Power SupplyPLC = PLC Digital Input Module。

ECSW系列单相窗口电流传感器用户手册说明书

Reset: Remove input voltage or open latch switch. If zero current detection is selected, the unit will reset as soon as zero current is detected.
Operation With Zero Current Detection Enabled: If the current decreases to zero within the trip delay period, then zero current is viewed as an acceptable current level. The unit's output remains in its normal operating state. This allows the monitored load to cycle ON and OFF without nuisance tripping the ECSW. Zero current is defined as current flow of less than 250 milliampturns. Note: When zero current detect is selected, the latching operation of switch SW2 is canceled; the output will not latch after a fault trip.

CLS2容电水位传感器安装和操作指南说明书

Series CLS2 Capacitive Level SwitchSpecifications - Installation and Operating InstructionsBulletin L-26The CLS2 Capacitive Level Switch was designed to sense material level in a wide range of applications and environments using the dielectric properties of the sensed material. State of the art sensing technology in the CLS2, using impulse RF admittance measurement combined with an active guard, provides excellent level measurement and stability while being insensitive to material buildup. This technology also provides immunity to external RF sources like walkie-talkies and cell phones as well as minimal interference with radio communication or other electronic systems.The product features automatic calibration and 8 selectable sensitivity levels. Calibration may be initiated with either the internal switch or using the external calibration magnet allowing calibration without removing the cover. A selectable failsafe mode allows the relay to be active either normally open or normally closed. The unit also features an active guard mechanism that effectively eliminates the effects of material buildup on the probe. A selectable delay is provided to ensure false detection due to splashing or other tank disturbances will not cause nuisance triggering. A high brightness LED indicator is provided externally so that the level status can be easily seen even in bright sunlight. Three multicolored LEDs are provided internally for maintenance anddiagnostic use.OPERATING PRINCIPLECapacitance and DielectricsCapacitance is the property of two or more conductors to store a charge when there is a voltage difference between the conductors. In other words, capacitance relates the voltage between two conductors and the amount of charge that can be held on the conductors (i.e., the number of electrons). Capacitance is measured in Farads, but since a Farad of capacitance represents a very large charge storage capacity, most capacitance encountered is generally measured in micro Farads (µF, 10-6) or pico Farads (pF, 10-12). Capacitances encountered in level sensing applications are generally in the pico Farad range.The material between the conductors also affects the capacitance. Insulating materials do not allow free movement of electrons, however, in an electric field the molecules of these materials will tend to align with the field, thus storing energy. This is called the dielectric effect and these materials are often referred to as dielectrics. When placed between two conductors the energy storage capability of these dielectrics will allow more charge to be stored on the conductors for a given voltage difference thus increasing the capacitance between the conductors. The ratio of capacitance change caused by these dielectrics is referred to as the dielectric constant. Different materials have differing dielectric constants and will consequently change the capacitance between two conductors more or less depending on the value of this constant. This value ranges from 1.0 for a vacuum to over 100 for certain materials. The dielectric constant for air is very close to 1.0 and usually assumed to be exactly 1.0.Capacitive level sensors determine the level of material by changes in probe capacitance resulting from the movement of dielectric materials between the probe and the reference ground such as a tank wall. Since measuring very small capacitance changes (less than 1 pF) can be problematic in industrial environments, capacitance level sensing tends to be most effective for materials with a dielectric constant greater than about 1.2. Since the difference in capacitance is being measured, it is also possible to detect the level of two immiscible liquids that have different dielectricconstants such as oil and water.Level DetectionThe CLS2 uses the capacitance difference between the uncovered sensor and covered sensor to sense level such as the probe in air verses the probe in oil. This would allow, for instance, detection when the level in a tank is below a threshold and a pump must be started or when the level is above a threshold where the pump must be turned off.The CLS2 can be used in applications were the probe gets coated or covered with sticky, dusty, or clingy materials. The CLS2 has an active guard near the top that compensates for material that coats the probe preventing false alarms.When detecting level, two critical items must be established: a reference capacitance and the sensitivity. The reference capacitance is set through an automatic calibration process. The sensitivity is selected using an internal DIP switch which provides 8 sensitivity levels to accommodate differing material dielectric constants. See the calibration section for specific calibration instructions.The level detection is available to external systems through a double pole double throw (2-form C) relay. In any alarm or control system some consideration must be made for a power failure in one or more elements of the system. The CLS2 provides a fail-safe selection that allows the relay to operate in either a normally open or a normally closed state when the probe is uncovered.INSTALLATION UnpackingRemove the CLS2 from the shipping carton and inspect for damage. If damage is found, notify the carrier immediately.Mounting LocationThe CLS2 is designed to be mounted in a tank and is rated for industrial environments with few restrictions, however certain considerations must be made to ensure optimal sensing and extended operational life.• The process temperature and ambient temperature must be within the specified limits for the instrument.• Avoid locating the unit near or in high mechanical shock or vibration areas. • The probe must be located away from tank inlets or chutes where material may fall on the probe during filling or emptying.• Avoid mounting the probe close to tank structures as conductive product bridging between the guard and tank structure can cause false alarms. • In nonmetallic tanks a ground reference must generally be provided. If the probe is near the wall of the tank an adhesive backed metallic sheet may be applied to the outside of the tank wall nearest to the probe. Other metallic objects may be used also if they are in close proximity to the tank wall. If the probe is located further than 10 inches from the wall, an internal conductor must be providedparallel to and within 10 inches of the probe. These conductors must be connected to the case ground of the sensor. An external ground clamp is provided for this ifother grounding is not available.Note: Installation must be made in accordance with National Electric Code and local codes and regulations. When fishing wire through the conduit connection do not allow the wire to touch or press on components on the boards. Damage to the circuitry may result.The unit is to be wired to a switch or circuit breaker in close proximity to the unit. The switch or circuit breaker shall be marked as the disconnections device for the unit.The CLS2 has a 1/2˝ female NPT conduit connection. The conduit connection must be made such that condensation is not allowed to enter the housing.Grounding: The case of the CLS2 must be wired to a protective earth ground. This may be done by using a metal conduit or by wiring to one of the protective earth groundscrews in Figure 1 or Figure 2.The terminal block may be removed for easier connection. To remove, place a small screwdriver between the terminal block and the connector base and pry the terminal block forward. This will unlatch the block from the base allowing it to be removed. When installing the block, tip it forward on the connector base to snap it in the forward locking tab then rock the connector back onto the contacts until it snaps in place. Make sure the terminal block is securely in place.Strip 0.25˝ of insulation from the wires. Connect the power wires to terminals 1 and 2. If powered by DC, the polarity is not critical and either terminal may be selected for positive or negative. Connect control lines to the relay contact terminals (see Figure 1 for terminals).

It is affected by the failsafe setting and the delay.Power LED —Green. This LED is illuminated when the unit is powered and indicates that power is being supplied to the sensing circuitry.External LED—Red. The external LED indicator operates in conjunction with the internal Output LED.External Calibration Magnet —An external magnet is provided on the end of a chain to initiate calibration without having to open the case. Calibration is started by touching the magnet to the label target twice.Always install or service this device with the power off and whererequired install a disconnect lockout.For power line connections use NEC Class 1 wiring rated 75°C. Use 12 to 20 AWG copper only for line and load connections.Torque terminals to 5 in-lb.

Fail Safe Mode Selection: The relay will always be off when the power fails. In this case the contacts identified as normally open will be open. The fail safe switch selects whether the normally open contacts are open or closed when the probe is uncovered. There are two options for the failsafe condition that are selected by DIP switch S4 (see Figure 2). Selecting normally open (NO) will force the relay contacts to be open when the probe is uncovered and the output status LED to be off.Selecting normally closed (NC) will energize the relay when the probe is uncovered and light the output status LED.2. Sensitivity Selection: The sensitivity must be selected to match the dielectric constant of the material and its density. Eight sensitivity levels are provided by positioning DIP switches S1, S2, and S3 (see Figure 2). A high sensitivity setting is a low pF, and a low sensitivity setting would be a high pF. High sensitivity is used for materials such as plastic pellets, light powders, and dry grain. Mediumsensitivity is used for materials such as cement, petroleum products, and flour. Low sensitivity is used for products such as aqueous solutions. The switchpositions are summarized in Table 1. For best operation use the minimal sensitivity required for reliable operation.3. Calibration: Calibrate with the probe uncovered and the material at least 5 inches below the probe.To start the automatic calibration process press the calibrate switch twice (see Figure 2) or press the external magnet up to the housing at the marked location on the housing twice (see Figure 3). The external magnet is attached to the housing by a chain. The output status LEDs will begin to blink slowly, about once per second, when the calibration process has started. The automatic calibration will take approximately 10 to 15 seconds, and the output status LEDs will stop flashing at the end of the calibration process. If during the calibration process the tank level changes or a sensor failure has occurred, the calibration process may fail. The output status LEDs will begin to flash rapidly (about 4 times per second). Makesure the probe is uncovered and retry the calibration step.Table 1: Switch position for sensitivityFigure 3: Magnent location4. Time Delay Selection: The time delay is the programmed time between when the probe senses the material and when the relay changes state from the sensed material. A time delay of 3 seconds or greater is required to meet CE requirements. Choose a delay setting appropriate for the specific application. Adjust the delay potentiometer to the desired delay (see Figure 2). The delay can be set anywhere from 0 to 60 seconds and a scale is printed on the sensor board. For verification of delay programming the yellow sensor LED will come on when material is sensed and the red output LED will come on with the relay after the programmed time delay.5. Verify Operation: Make sure the probe is uncovered, material at least 5 inches below the probe, and that the yellow sensor LED is off. Fill the tank until thematerial is at the desired threshold level and verify that the sensor LED is illuminated. If the sensor LED turns on before the material reaches the probe, reduce the sensitivity as needed. If when the probe is covered the sensor LED is notilluminated, increase the sensitivity. Water or other conductive liquids will activate the sensor when they just contact the probe. Low density and dielectric constantmaterial may require more of the probe to be covered.Note: Default values as the product ships from the factory is a follows: S1:off, S2:off, S3:on, S4:on, and time delay off.MAINTENANCEOther than the controls mentioned in this manual there are no user maintenance adjustments or routine servicing required for this product. Very heavy buildup on the probe may ultimately reduce sensitivity. Moderate buildup is compensated for by the active guard.The Series CLS2 Capacitive Level Switch is not field serviceable and should be returned if repair is needed (field repair should not be attempted and may void warranty). Be sure to include a brief description of the problem plus any relevant application notes. Contact customer service to receive a return goods authorization (RGA) number before shipping.When the CLS2 with a Sanitary Process Connection is to be used in a sanitary or hygienic application, the unit must be cleaned and/or sanitized in accordance with appropriate guidelines prior to installation.

电池管理系统作为电动汽车电池，电机，电控三大技术的重要组成部分，肩负着实时监控和管理电池状态的重要任务。

准确估算电池荷电状态（SOC），对电池能量高效管理和整车性能提升有着重要的作用[1]。

电池的SOCs受到开路电压，充放电电流，温度，自放电，充放电次数等因素的影响，使得对其估算具有较大的困难[2]。

本文主要研究了锂离子等效电路模型，并且开发出基于安时积分法，开路电压法和负载电压法相结合的锂离子电池SOC估算算法[3]。

并经过了放电实验的验证，算法可行，估算精确。

电池SOC是反应电池剩余电量的重要参数，人们通常将电池的SOC作为评估电池电量的重要标志。

电池的荷电状态表示电池剩余容量占电池总容量的比值[3]。

安时积分法是估算电池SOC值是通过充放电过程中放电电流对时间的积分得出的电量变化值的方法。

西门电气 RFS流量传感器使用说明书

RFS流量传感器安装使用说明书选型、安装及使用参考无机械运动部件，安装、使用维护方便低功耗温敏传感器，灵敏度高，精度高先进数字化处理技术，抗干扰能力强，结构紧凑，体积小，安装维护方便1 产品概述RFS流量传感器是一种流速传感监测装置，主要功能是检测流速的大小，当流速未达到设定的流速阀值时发出报警信号，并由控制系统进行报警或启动连锁保护装置关闭关键设备，及时制止在生产中的突发事故，因此该装置是保证生产安全、降低企业经济损失的不可缺少的重要装置，它具有不可估量的作用。

2 工作原理RFS流量传感器由两个温度传感器、电源、信号Array处理器及输出继电器或NPN/PNP晶体管输出组成。

该类型的温度传感器使用特殊的半导体制造。

这两个传感器物理特性非常接近，且以一定距离相互分离，相互间热影响可以忽略。

传感器配对跟踪介质的温度。

这些传感器的电压降与温度成正比，并准确的宽温度范围内工作。

将其中的一个传感器（Sensor1）进行加热，使其高于介质温度。

另一个传感器（Sensor2）与介质温度相同，我们基准传感器。

相等的恒流流经两个传感器产生电压差，其大小与Sensor1上被介质吸收带走的热量多少成反比。

由于介质的流速与带走热量成正比，故通过测量两个传感器的电压差，可知介质此时的流速，从而通过计算知道介质的流量。

火闸传感器使用指南说明书

TM WST-600 AUDIO DETECTOR US Patent # 9,087,447Installation Manual & Users GuideSPECIFICATIONSFrequency: 433.92MHz Operating Temperature: 32°-120°F (0°-49°C) Battery: One3Vdc lithium CR123A (1550 mAh) Operating Humidity: 5-95% RH non condensingBattery life: 4 years Compatible with 433MHz DSC Security SystemsDetection distance: 6 in max Supervisory signal interval: 64 min(approx.)OPERA TIONThe FireFighter™ sensor is designed to listen to any smoke, carbon or combo detector. Once confirmed as an alarm, it will transmit a signal to the alarm control panel which if connected to a central monitoring station, will dispatch the fire department.ENROLLINGFollow the instructions provided by your control panel, or wireless receiver manual. The 6 digit serial number is printed on back of each device. To monitor smoke alarms, when prompted by the panel, enter the 6 digit serial number as printed on the device. Use either zone type 88 ( Standard 24hour fire) or type 87 (Delayed 24 hour fire). Remember to set the wireless bit (bit 8) for that zone attribute.To monitor a CO detector, take the printed serial number and replace the first digit with an 8. For example if the number printed is 436A48, you woulduse 836A48 as the serial number for the CO portion. Use zone type 81 (24 hour Carbon Monoxide).MOUNTING (see IMAGE: 2)Included with this device is a mounting bracket, hardware and double sided tape. To ensure proper operation ensure the side of the device with the small holes is directly facing the sounder holes on the smoke detector. Secure the mounting bracket to the wall or ceiling using thetwo mounting screws and double sided tape provided, then secure the audio detector to the mounting bracket using the small screw provided. The FireFighter™ must be mounting within 6 inches of the detector for optimal operation.***** It is possible that the sensor can hear other smoke detectors in close proximity so it is important to choose and to install the sensor close to a detector that is relatively isolated from other detector. It that is not possible, the sensor will still function it will however take longer to register and transmit to the panel. Smoke detectors to avoid are typically ones mounted in hallways outside of bedrooms that will also have additional smoke detectors.WARNING: Non-interconnected smoke detectors require an audio detector by each smoke detector sounder.This equipment should be installed in accordance with Chapter 2 of the National Fire Alarm Code, ANSI/NFPA 72, (National Fire Protection Association, Batterymarch Park, Quincy, MA 02269). Printed information describing proper installation, operation, testing, maintenance, evacuation planning, and repair service is to be provided with this equipment. Warning: Owner’s instruction notice: ’Not to b e removed by anyone except occupant’.TESTING (see IMAGE: 1)To test the RF transmission from the mounted position you can either generate a tamper by removing the cover or press the learn button located next to the tamper switch. Press and release ONCE to send a Smoke signal or press and HOLD for 2 seconds to send a Carbon signal.Within the first hour of power up the sensor is in a test mode. This mode is designed to work with the test button of the smoke detector so that only 1 or 2 temporal patterns is required to trigger the sensor. After the 1 hour has elapsed the sensor will require at least 3 rounds of either temporal 3 (smoke) or temporal 4 (CO) before it will send a transmission to the control panel. . Ensure the FireFighter™ cove r is on and that you wear hearing protection when doing the audio testing. Then simply press and hold the smoke detector test button.If 24 Hr, delay fire zone type is used the alarm must be active for 30 second before the panel will transmit to the Central Station.NOTE: This system must be checked by a qualified technician at least once every three (3) years. Please test the unit once per week to ensure proper functionality.Legacy Smoke DetectorsAll Smoke detector should be replaced after 10 year. If you encounter a smoke detector that does not support Temporal 3 pattern, that smoke should be replaced as per the manufacturer recommendation.If replacement is not an option the FireFighter can be program to detect non-temporal detectors.** In this mode, the sensor must not be located near any other audible device, like the security keypad or sounder. Those can be misconstrued as a valid smoke alarm. To enter this mode press and hold the tamper button while inserting the battery. Release the tamper switch and note the LEDONE flash: Only a Temporal 3 and 4 signal will trigger an alarm (Default)TWO flashes: Generic listening mode. (Will trigger after 30 seconds of continuous sound)You can verify the mode the device is in by simply removing the battery and replacing it. The LED will flash once or twice depending on the mode it is in. Repeat the steps above to change the mode as required.REPLACING THE BATTERYWhen the battery is low a signal will be sent to the control panel. To replace the battery:1. Remove the top cover to reveal the battery. This will send a tamper signal to the control panel.2. Replace with a Panasonic CR123A battery ensuring the + side of the battery faces as indicated on the device.3. Re-attach the cover, you should hear a click when the cover engages properly.WARNING: While the audio detector monitors its own battery, it does not monitor the battery in the smoke detectors. Batteries should be changed as per the original smoke detector manufacturer’s instructions. Always test the audio detector and smoke alarms after battery installation to confirm proper operationFCC COMPLIANCE STATEMENTThis equipment has been tested and found to comply with the limits for Class B digital devices, pursuant to Part 15 of the FCC Rules.

WD-C互感器校验仪说明书

WD-C互感器校验仪武汉武高电测电气有限公司一、互感器检验仪简介1．11电流互感器电流互感器：：电流互感器电流互感器和变压器很相像，变压器接在线路上，主要用来改变线路的电压，而电流互感器接在线路上，主要用来改变线路的电流，所以电流互感器从前也叫做变流器。

后来，一般把直流电变成交流电的仪器设备叫做变流器，把改变线路上电流大小的电器，根据它通过互感的工作原理，叫做电流互感器。

线路上为什么需要变电流呢？这是因为根据发电和用电的不同情况，线路上的电流大小不一，而且相差悬殊，有的只有几安，有的却大至几万安。

要直接测量这些大大小小的电流，就需要根据线路电流的大小，制作相应为几安直到几万安不同的许多电流表和其他电气仪表。

这样就会给仪表制造带来极大的困难。

此外，有的线路是高压的，例如22万伏或1万伏等高压输电供电线路，要直接用电气仪表测量高压线路上的电流，那是极其危险的，也是绝对不允许的。

如果在线路上接入电流互感器变电流，那么就可以把线路上大大小小的电流，按不同的比例，统一变成大小相近的电流。

只要用一种电流规格的电气仪表，例如通用的电流为5A的电气仪表，就可以通过电流互感器，测量线路上小至几安和大至几万安的电流。

同时电流互感器的基本结构和变压器很相像，它也有两个绕组，一个叫原边绕组或一次绕组；一个叫副边绕组或二次绕组。

两个绕组之间有绝缘，使两个绕组之间有电的隔离。

电流互感器在运行时一次绕组W1接在线路上，二次绕组W2接电气仪表，因此在测量高压线路上的电流时，尽管原边电压很高，但是副边电压却很低，操作人员和仪表都很安全。

由此可见，电流互感器除了可以将线路上大小不一的电流变成一定大小的电流，以便于测量之外，还可以起到与线路绝缘的作用，以保证操作人员和仪表的安全。

1.1.1测量用电流互感器测量用电流互感器的用途，主要有下列两方面：⑴用来测量高压线路上的电流和功率，起绝缘隔离的作用，以保证操作人员和仪表的安全。

⑵来测量高压或低压线路上的大电流和大功率，使用统一的5A的二次线路和测量仪表。
