Precision Current Transducers

With the ULTRASTAB precision current transducer program LEM Danfysik offers current transducers from 40 A to 25 kA covering the whole range in metrology class. The precision current transducers are using a zero flux principle, controlling a compensating winding which counter balance the ampere turns generated of the primary current. Due to the balanced zero flux detector principle the output noise level is by nature very low and resolutions in the order of 2 x 10-8 is achieved.
