Current sensing from low frequency 0.001Hz to 6.5MHz
The CWT LF current sensors are rugged clip on, flexible sense coil, high frequency current probes, using Rogowski Coil technology for wide bandwidth measurement and faithful conversion of ac current to voltage, intended for use with oscilloscopes, data loggers, transient recorders, power meters and power analyzers - ideally suited for power electronic applications. Based on the Rogowski principle, these probes have intrinsic high bandwidth performance allowing measurement of both small and large currents (1A-600kA) from 0.01Hz to 20MHz. The small coil profile (8mm dia), means the coil can be retrospectively installed without disruption to active power systems. As standard, the coil is insulated at 10kVrms, insulation can be increased if required. Models are available with a variety of clip-around coil sizes to suit most conductors, allowing easy current monitoring even where access is limited.
