Product Description
Flexible coil fixed by cable ties
Rogowski coils have been used for the detection and measurement of electric currents for decades. They are based on a simple principle: an “air-cored” coil is placed around the conductor in a toroidal fashion and the magnetic field produced by the current induces a voltage in the coil.

Feature
・High linearity from 1Ato 1000A ・Wide dynamic range ・Very useful with large size or awkward shaped conductors or in places with limited access ・No danger from open-circuited secondary ・Not damaged by large overloads ・Non-intrusive, no power drawn from the main ・Measurement uniformity at any position of the conductor inside the coil ・Excellent degree of rejection to the external current conductor
Advantage•Calibrated to 0.5% •8mm section easy to install •Easy to fixed on bus-bar and cable by cable ties •Lower zero drift down to 0.1mVRelated ProductsS1 D1 S9 SW A01 A05 ME631 ME437
Applications
•Measuring devices, lab instrumentation •Power monitoring & control systems •DC ripple measurement •Harmonics and transients monitoring •Power meter,Power analyzer sensor
