Application of Hall Effect Current Transducer in a Company in India

Hall current sensor is a kind of sensor that relies on electromagnetic characteristics to detect current. It can indirectly measure the current of the current-carrying conductor by measuring the Hall electric potential, making non-contact measurement of current possible. Hall current sensors mainly include open-loop and closed-loop types, which have the advantages of short response time, high operating frequency, strong overload capacity, and high isolation. It is suitable for measuring the complex electric quantity of various frequencies and various waveforms. It is widely used in variable frequency speed regulation devices, inverter devices, UPS power supplies, photovoltaic power generation, communication rooms, CNC machine tools, microcomputer monitoring systems, grid monitoring systems and various fields that require isolation and detection of current.

1. Project Overview

The Indian company's business covers pumps, charging piles, solar energy, etc. The Hall current sensor they purchased is mainly installed PLC. Originally, customers need 0-20 mA output, but at 0 mA, it is not possible to distinguish whether it is true 0 mA or no signal output. In the end, the customer thought that 4-20 mA output is more reasonable, so we use our AHKC series Hall current sensor with 4-20 mA output.

2. AHKC Series Hall current sensor

Hall sensor is suitable for the isolation and conversion of complex signals such as AC, DC and pulse. Through the Hall effect principle, the converted signal can be directly collected and accepted by various acquisition devices such as an ad, DSP, PLC and secondary instrument. It has the advantages of small volume, long service life, convenient installation, fast response time, wide current measurement range, high precision, strong overload capacity and good linearity, It has the advantages of strong anti-interference ability.
