0-20mA Output Class 0.2 Railway Usage Current Sensor

Product Description

PRODUCT OVERWIEW

A new type of current sensor developed by applying the principle of magnetic modulation. The primary current is compensated by the current generated by the internal oscillator to achieve the balance of the magnetic field. At this time, the secondary voltage can accurately reflect the primary current.

Product Features

Small current measurement performance is stable

Excellent accuracy, good linearity

Wide measuring range and strong overload capacity

Perforated structure, no insertion loss

Scope of Application

The signal system

Line detection

Leakage Monitoring System

Current difference measurement
