. Brief

ETCR 200F Flexible coil current sensor (Rogowski Coil ), use of advanced Rogowski coil technology, is a toroidal coil wound on a non-uniform ferromagnetic material, no hysteresis effect ,phase error is almost zero, and no magnetic saturation, high linearity. The output signal is current on the time differential, the output voltage signal by integrating the input current can be true to, the measurement current range from milliamps to tens of thousands of ampere. Mainly used for measure AC leakage current, AC big current, high harmonic currents (Up to 400 times), complex Waveforms current,   inrush transient current, Phase, electric energy, power, power factor. With an integrator, ease of integration to other devices, such as the phase detection analyzer, industrial control devices, data loggers, oscilloscopes, harmonic analyzer, power quality analyzers, high-precision digital multicenter, transients

recorder, distributed measurement systems, protection systems.

ETCR 200F No exposed metal conductor, non-contact measurement, safe and reliable; Small size, light weight, soft and flexible, suitable for cramped environment and cable-intensive sites, And measure the size of a large or irregularly shaped conductor current; Wide measurement range, high accuracy, reliability, response, bandwidth (0.1Hz-1MHz); Coil length can be customized according to user requirements, Particularly suitable for relay protection, silicon controlled rectifier, frequency control , semiconductor switches, Power electronics conversion equipment, arc welding and other industrial environments serious signal distortion.
