The Power Instruments Frequency Transmitter is a high-precision industrial device designed to continuously monitor AC power frequency and convert it into a standard isolated signal output (such as 4-20mA, 0-10V, or RS485). Utilizing advanced isolation technology, it delivers accurate, real-time frequency readings with strong anti-interference performance, even in electrically noisy environments. The transmitter supports flexible DIN-rail or panel mounting and easily integrates with PLC, DCS, and SCADA systems. Ideal for power plants, substations, and automated industrial facilities, it ensures stable grid frequency tracking and reliable data transmission for effective power quality management and process control.
