It is a high precision DC high current measurement device based on the Faraday Magneto-optical Effect and the Ampere Loop Theorem. The sensing optical fiber is fixedly mounted on the high current bus-bar through a skeleton and forms a closed optical fiber loop. The magnetic field generated by the high current in the bus-bar causes the phase shift of two light waves in the optical fiber, and the current value is measured by demodulating the phase shift of the light waves.

Key Features

Resistant to interference from stray magnetic fields, easy installation and commissioning, display and recording of operating status, designed for harsh environments

Application area

Suitable for a variety of large current measurement, especially metal smelting, electrochemistry and other fields of industrial large current accurate measurement and control.
