Application of Acrel Hall Sensor in Indonesia

　　1. Abstract: 

　　This article introduces the application of the Hall Sensor used in Indonesia. 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 the quick response, wide range of measurement, high precision, strong overload capacity, good linearity and excellent anti-interference performance. 

　　2.Project overview: 

　　The company in Indonesia who make the traffic light system and need to use DC hall sensor to transmitter the DC current to 4-20mA analog signal output. After they choose the hole size, input ratio, output ratio and working power supply, the customer chosen the AHKC-EKAA as their best choice. 

3.Classification 

　　Hall sensors are divided into three categories according to the principle: open loop Hall current sensor, closed loop Hall current sensor, Hall voltage sensor.
