Hall magnetic sensor

Product introduction

Because there is a magnetic field around the energized wire, and its size is directly proportional to the current in the wire, the magnetic field can be measured by Hall element to determine the size of wire current. Using this principle, Hall current sensor can be designed and made. The utility model has the advantages of no electrical contact with the circuit under test, no influence on the circuit under test and no power consumption of the power supply under test. It is especially suitable for high current sensing. By detecting the change of magnetic field, Hall element is transformed into electrical signal output, which can be used to monitor and measure the change of operating parameters of automobile components. For example, position, displacement, angle, angular velocity, rotational speed, etc., and these variables can be transformed twice; It can measure pressure, mass, liquid level, flow rate, etc. The output of hall device is directly connected with the electronic control unit, which can realize automatic detection.
