Another important application of Hall effect sensors is current measurement involving high voltage. In a resistive current detection circuit, a differential amplification resistor measures the voltage difference between one end and the other end of a resistor. However, when these voltages are high relative to the ground potential, a problem arises:

In real life, amplifiers have a limited "common mode range", which means that when the input voltage is relatively small but too high relative to the ground, the device will not function properly. The common mode range of current sense amplifiers generally does not exceed 80 or 100 volts for Hall effect sensors. On the other hand, current can be converted into voltage without reference to the ground potential of the circuit being tested. Therefore, as long as the voltage is not high enough to cause physical damage, the common mode voltage will not affect the operation of Hall effect devices.

58彩票Hall effect sensor is a useful technology that utilizes the Hall effect as a switch for operation. These devices are typically used for proximity sensing applications, providing designers with a small-scale, flexible solution. As the company continues to develop and improve this technology, it seems that these devices will still be widely used. Our product has an isolation voltage of up to 6KV.
