Current Sensor AC/DC Current Transducer Aperture 20mm Input AC0.5A~300A
Product Features
A Current Sensor is a device that accurately measures AC or DC current flowing through a conductor and converts it into a standardized output signal, such as 4–20 mA, 0–10 V, or digital signals, for monitoring, control, and protection purposes. It provides high accuracy, fast response, electrical isolation, and reliable performance, ensuring precise and interference-free measurement in various environments. Current sensors are widely used in industrial automation, energy management, motor control, power distribution systems, renewable energy applications, and smart grids. By delivering real-time current data to control systems such as PLCs, SCADA, or DCS, they enable fault detection, load monitoring, energy optimization, and preventive maintenance, enhancing operational safety and efficiency. Compact, robust, and easy to integrate, current sensors play a critical role in improving system reliability, performance, and intelligent monitoring in modern electrical and industrial applications.

Application examples
Example 1
Universal two isolation common ground output (one in, one out) is often used in this situation, where the power supply of the signal acquisition device is the same as that of the current transmitter, or the power supply of the current transmitter is directly provided by the signal acquisition device.
Example 2
The two-wire output (DC4~20mA) only requires 2 wires for output and power supply, which can save 1 wire compared to a general transmitter, reduce wire costs, and improve the reliability of the transmitter.
