Zero Power Consumption Sensor WG214

Product catalog summary

Features:

No power supply needed during operation.
Bipolar excitation mode outputs positive and negative pulse signals when magnetic field polarity changes.
Stable and reliable operation as pulses are only output when magnetic field polarity changes and reaches excitation threshold.
Signal amplitude is independent of magnetic field change speed, allowing operation at near-zero speed.
Simple signal processing, compatible with transistors, comparators, and A/D converters.
Output signals can be remotely transmitted, suitable for LAN management.
No mechanical contact or sparks, ensuring intrinsic safety.
Wide operating temperature range and strong environmental adaptability.

Performance Index:

Excitation strength: Min 3 mT, Typ 5-6 mT, Max 12 mT.
Pulse signal amplitude: ≥1.5 V.
Pulse width: 10-30 μS at 1V location.
DC internal resistance: 650-850 Ω.
Operating frequency: Min unlimited, Max 10 kHz.
Operating temperature: -40 to +125 ℃.
Sensitive silk location: 2.5 mm from sensor bottom.
Package: Plastic shell, Epoxy potting.

Applications:

Rotation count: Smart water meters, heat meters, gas meters, fuel gauges, flow meters, odometers.
Position detection: Oil depot level detection, tipping bucket rain gauge, unattended hydrometeorology monitoring.
Electronic switch: Explosion-proof switch, ignition switch.

Installation Notes:

For water meter applications, use a magnetic ring of φ9.5×φ6.0×3.5 mm, magnetized axially with a surface magnetic strength of over 90 mT. Installation distance from ring surface to sensor bottom should be about 2.5 mm.
Magnetic strength requirements must be met; too strong or weak fields may affect operation.
Different magnet materials and shapes require magnetic field measurement and installation distance adjustment.

南京艾驰电子科技有限公司 WG214 Zero Power Consumption Sensor No need the power supply when it works. Bipolar excitation working mode, the with the magnetic field changing speed, and sensor outputs a pair of positive and it can work at the speed near to zero.  negative electrical pulse signal when the The signal amplitude has nothing to do The signal processing is simple, and it can magnetic field polarity changes for a circle.  be directly connected with transistors, Only when the external magnetic field polarity changes, magnetic strength reaches The output signal can be remote transmitted by the signal lines, it’s suitable for LAN the excitation threshold, the sensor will outputs a pulse signal, so the vibration No mechanic contact, no spark, is a kind of intrinsic safety devices. won’t happen. The operation is stable and Wide operating temperature range, strong environmental adaptability. ◆ Performance Index Name Excitation strength Pulse signal amplitude Pulse width（in the location of 1V） Operating Temp.
