Features
No need the power supply when it works.
Sensor dimension and sensitive silk location
InstructionIn the water meter application, the magnetic ring of φ9.5×φ6.0×3.5 mm can be used, it is magnetized in axial direction, a pair of poles. The surface magnetic strength is more than 90 mT, the installation distance from the surface of ring to the bottom of the sensor is about 2.5mm.
Note: The sensor has certain requirements to the magnetic strength, too strong or too weak magnetic field may affect its operation.(See the excitation strength on "Performance index" )
If using other material and shape of the magnet, it needs to measure its magnetic field, and adjust the installation distance.
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.
