LEM ART-B22-D125-SP3, AC Measurement Rogowski Coils (coil only). 12.5cm Diameter, Class 0.5, 3M Shielded Cable Connection
Flexible clip-around Rogowski coil for the electronic measurement of AC current with galvanic separation between the primary circuit (power) and the secondary circuit (measurement). The patented Perfect Loop Technology dramatically reduces both the error due to the position of the measured conductor within the aperture, and the error due to the proximity of external conductors.
The ART series single phase flexible rope CT from LEM. In conjunction with AI-PMUL combined integrator & signal conditioner LEM offer True RMS 0-5V, 0-10V, 0-20mA, 4-20mA outputs, or direct linear outputs 0.333V or 0.166V
Included is a 12.5cm diameter rope CT, and 1.5M of twisted pair (1000V) output leads for connection to an integrator, or meter/logger with integration function.
LEM coils come with 5 year warranty
