The Ultrastab range of high performance current transducer allows the electronic measurement of DC, AC and pulsed currents with galvanic isolation between the primary (high power) circuit and the secondary circuit with <5ppm linearity and accuracy.
IT current transducers are high accuracy, large bandwidth transducers which do not use Hall generators. The magnetic flux created by the primary current is compensated by a secondary current. The zero-flux detector is a symmetry detector using two wounded cores connected to a square-wave generator. The secondary compensating current is an exact representation of the primary current.
