Zero Power Magnetic Sensor (WG214) , Water Meter, Flowmeter, Heat Meter, Energy Meter, Gas Meter, Li

1. No need the power supply when it works.2. Bipolar excitation working mode, the sensor outputs a pair of positive and negative electrical pulse signal when the magnetic field polarity changes for a circle.3. only when the external magnetic field polarity changes, magnetic strength reaches the excitation threshold, the sensor will outputs a pulse signal, so the vibration won't happen. The operation is stable and reliable.4. The signal amplitude has nothing to do with the magnetic field changing speed, and it can work at the speed near to zero.5. The signal processing is simple, and it can be directly connected with transistors, comparators, A/D converter, etc.6. The output signal can be remote transmitted by the signal lines, it's suitable for LAN management.7. No mechanic contact, no spark, is a kind of intrinsic safety devices.8. Wide operating temperature range, strong environmental adaptability.The Choosing Guide for Zero Power Consumption Magnetic SensorModelSignal Type Zero Power Consumption SensorPower Type Zero Power Consumption SensorWG112WG113AWG214WG215WG311WG314WG315WG711WG611WG612WG621Magnetic induction strength B(mT)Min.32.53535Optimal5~67~85~67~85~67~8Max.12151212Output amplitude Vo(V)≥1.5≥2.0≥1.5≥3.0≥6.020~50Pulsewidth τ(μS)10~3030~4030~50DC resistance (Typical values) Ro(Ω)7001000750700150065013009007006001400Operating Frequency F(kHz)Min.Not limitedNot limitedMax.1051Operating temperature T(ºC)Min.-40-20-40-40Max.12585125100210100Overall dimension (mm)12.8x4.5x4.512x7.2x8φ4x11.5φ3.3x22φ5x11.524x6x624x9x918x6.7x11.8Sensitive wire position (mm)Distance bottom surface of sensor 2mmDistance bottom surface of sensor 2.5mm-Central axisCentral axisPackagePlastic housing, Epoxy pottingAluminum housing, Epoxy pottingThermal casingClinker housing, Epoxy pottingPlastic housing, Epoxy pottingOuter leadTinned copper, hard lead wireResistant high temperature soft lead wireTinned copperTinned copper, hard lead wireMain applicationsWater meter, Heat meterLarge caliber waterHeat meterWater flow rate sensorFlowmeter switchIndustrial flowmeter, pulse signal generatorIndustrial flowmeterEncoder transient power supplyNote 1: Special specification can be customized.Note 2: 1 mT= 10 Gs
