The most prominent feature of magnetic sensor applications is contactless measurement. Hall element: magnetic field measurement, do Gaussian meter (Tesla meter) detection probe. Current detection, a current sensor / transmitter components. DC brushless motor for detecting rotor position and providing excitation signals. Speed / rpm measurement of integrated switching Hall devices. Strong magnet film magnetoresistive devices: displacement sensors, mainly magnetic linear long-distance displacement measurement. Angular displacement sensor, the main term rotation angle measurement, widely used in automobile manufacturing industry. Pulse sensor, mainly used for traffic detection and speed / speed measurement, such as electronic water meter and flowmeter send the sensor. Semiconductor magnetoresistive device: mainly weak magnetic field detection InSb magnetoresistive device, mainly used for counterfeit currency recognition pulse measurement, mainly used for speed / rpm measureme...

Rotation count：Smart water meter, heat meter, gas meter, fuel gauge, flow meter, odometer etc. Position detection: oil depot level detection, tipping bucket rain gauge, unattended hydrometeorology monitoring. Electronic switch： Explosion-proof switch, ignition switch etc. Sensor dimension and sensitive silk location In 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. If using other material and shape of the magnet, it needs to measure its magnetic field, and adjust the installation distance. Related products:  Hall Sensor ,  Wiegand Sensor ,  Flow Meter
