Description
The RID-200 I-dot sensors are 2 or 4-turn toroidal mutual inductance current probes designed to measure the first time derivative of the total current through the toroid aperture. Applications include measurements of the current in a wire, structure or other conductor passing through the aperture, or a free space current such as a charged particle beam. The standard configuration is a fixed aperture with a differential 100 ohm output, but a split version and other output connector options can be provided on special order. Optional radiation hardened models are available.
