AC Current Sensor 4-20ma for Measurement TRJC100-20A
Technology Characteristics
Product Overview
Current Sensors are electronic devices used to measure the flow of electric current in a circuit. They detect AC or DC current and convert it into a proportional electrical signal for monitoring and control purposes. Common technologies include Hall effect, shunt resistor, and current transformer types. Current sensors are essential in power management, industrial automation, renewable energy systems, motor control, and smart grids. They help improve energy efficiency, ensure system protection, and enable precise current measurement. With high accuracy, fast response, and compact design, current sensors play a vital role in modern electrical and electronic applications.
