This article introduces the application of the Hall Sensor used in Chile. Hall current sensors are mainly used to isolate and convert AC, DC, pulse and other complex signals. After signal control of current signals are converted according to the Hall Effect Theory, they can be directly acquired by AD, DSP, PLC, secondary instruments and other devices. Hall current sensors are widely applicable for acquisition and feedback in the current monitoring, battery application, inverter, solar power management, direct current cabinet, DC motor drive, electroplating, welding, frequency converter, UPS servo control systems. They feature quick response, a wide range of measurements, high precision, strong overload capacity, good linearity and excellent anti-interference performance.
Project Overview
The company that does lithium batteries need to use DC Hall sensors to transmit DC current to the 4-20mA analog signal output. After confirming the input and output and working power, the customer chose AHKC-EKA and AHKC-EKAA.
Advantages of open type Hall sensor
Compared with the traditional DC current measurement method generally adopted by shunt or transformer, the open-type Hall sensor has the following advantages:
1) High insulation strength of primary side and secondary side, up to AC 12KV isolation;
2) No insertion loss;
3) Good dynamic performance: the response time is less than 20uS and the tracking speed Di /dt is higher than 20A/ uS
4) There is no need to disassemble the original side cable or bus during installation. It is especially suitable for the transformation and construction of equipment that is not allowed to lose power.
