Dent Instruments CTRCFX17L4000A7MSTV1 : 17" RoCoil Rogowski Coil Current Transformer, 5-4000A Range, 131 mVAC/1000A @ 60 Hz, 7M Leads
DENT R_Coil CTRCFX17L4000A7MSTV1 is a flexible Rogowski coil current sensor for accurate, non-intrusive AC current measurement from 5 to 4000A. It outputs 131 mVAC/1000A @ 60 Hz (109.2 mVAC/1000A @ 50 Hz) and supports 50/60 Hz systems. This model includes a 17" class coil with a 7 m (23 ft) lead set. Ideal for cable bundles, large bus bars, and tight panels where rigid-core CTs do not fit.
