The principle of measuring electric parameters with Hall sensor
Mar 30, 2020| Using Hall detection technology, we can overcome these shortcomings of the transformer, measure the AC signals of various shapes from DC to hundreds of kilohertz, and achieve the undistorted transmission of the original and secondary sides, at the same time, we can realize the isolation of the main circuit circuit and the electronic control circuit. The output of Hall sensor can be directly interfaced with the single chip microcomputer.
Therefore, Hall sensor has been widely used in microcomputer measurement and control system and intelligent instrument, and it is a new generation of product instead of transformer. In this paper, the hall sensor is used to measure the electrical parameters, especially the parameters of high voltage and high current.
The magnetic balance Hall current sensor is used to measure the current. The sensor can measure the alternating current from DC to 100kHz. In the automatic measurement and control system, it is often necessary to measure and display the relevant electrical parameters. At present, most of the measurement systems still use transformer type voltage and current transformers. Because of the non ideal nature of the transformer, there are large errors in the transformation ratio and phase measurement, which often need to be compensated by hardware or software, thus increasing the complexity of the system.https://www.ctsensorducer.com/
