Product Overview
The WG314/WG315 is a zero power consumption sensor that operates without a power supply. It functions in a bipolar excitation mode, outputting positive and negative electrical pulse signals when the magnetic field polarity changes. The sensor is stable and reliable, as it only outputs a pulse signal when the magnetic field polarity changes and reaches the excitation threshold, preventing vibrations.

Key Features

No power supply needed for operation.
Stable and reliable operation with no mechanical contact or sparks, ensuring intrinsic safety.
Wide operating temperature range and strong environmental adaptability.
Simple signal processing, compatible with transistors, comparators, and A/D converters.
Remote transmission capability suitable for LAN management.

Performance Index

Excitation strength: Min. 3 mT, Typ. 5-6 mT, Max. 12 mT.
Pulse signal amplitude: ≥2.0 V.
Pulse width: 10-30 μS.
DC internal resistance: 550-650 Ω for WG314, 1200-1400 Ω for WG315.
Operating frequency: Max. 10 kHz.
Operating temperature: -40 to +100 ℃.

Applications
The sensor is suitable for use in large caliber heat meters and industrial flow meters. It is designed for magnetic fields generated by multi-pole magnet rotation. Before installation, magnetic strength should be measured and installation distance adjusted accordingly. Note that the sensor requires specific magnetic strength levels for optimal operation.

Catalog excerpts

WG314&315 Zero Power Consumption Sensor-1

• No need power supply when it works. • 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. • 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. • The signal amplitude has nothing to do with the magnetic field changing speed, and it can work at the speed near to zero. • The signal processing is simple, and it can be directly connected with transistors, comparators, A/D converter, etc. • The output signal can be remote transmitted by the signal lines, it’s suitable for LAN management. • No mechanic contact, no spark, is a kind of intrinsic safety devices. • Wide operating temperature range, strong environmental adaptability.
