• 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.

Large caliber heat meter, industrial flow meter etc. Pulse signal generator without power supply. ◆ Sensor dimension and sensitive silk location ◆ Sensor dimension and sensitive silk location  WG314/WG315 is suitable for the magnetic field that generated by multi-pole magnet’s rotation. It can be applied in industrial flow meter. Before installation, it needs to measure the magnetic strength and adjust the installation distance. Note: The sensor has certain requirements to the magnetic strength, too strong or too weak magnetic field may affect its operation. NANJING AH ELECTRONIC SCIENCE ＆ TECHNOLOGY...
