Products summary

Rogowski coil integrator can restore the input current and has certain filtering and amplifying function, at the same time, so as to make the wave line smoother and more practical. It has the characteristics of wide measurement range, high precision, reliable voltage stabilization, wide response frequency band, etc., and is widely used in metallurgy, electroplating, welding, frequency control and other fields.

 

Products features

* Coil inner diameter can be customized according to the requirements, from50mm- 600 mm;
* The integrator output range can be selected from 0.1 V to 5 vac.
