Product Description

Product Description

Features

No need the 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.

Instruction

WG311 is suitable for the magnetic field generated by multi-pole magnet's rotation, and it can be used in the industrial flow meter. It needs to measure its magnetic field and adjust the installation distance before installation.
Note: the sensor has certain requirements to the magnetic strength, too strong or too weak magnetic field may affect its operation.
