A Current Transmitter is an electronic device that converts an electrical current input into a standardized output signal, typically 4–20 mA or 0–10 V, for accurate monitoring and control. It ensures precise measurement of AC or DC currents with high stability and electrical isolation. Commonly used in power systems, industrial automation, motor control, energy management, and smart grid applications, the current transmitter helps monitor load conditions, detect faults, and transmit real-time data to control systems such as PLCs or SCADA, ensuring safe, efficient, and intelligent operation of electrical networks and industrial equipment.
