High Frequency Current Probes and Rogowski Coils

CWT LF Wideband Current Probe
CWT LF low frequency wideband current probe 0.01Hz to 10MHz 10kV

The CWT LF current sensors are rugged clip around flexible coil wideband current probes, using Rogowski Coil technology for wide bandwidth measurement and faithful conversion of current to voltage, intended for use with oscilloscopes, data loggers, transient recorders, power meters and power analyzers.

CMC Rogowski Current Probe
CMC Rogowski Current sensing probe for detection of bearing spark erosion

Variable Frequency Drives (VSDs) used to control AC motors, can produce large high frequency currents that may appear on the machine shaft. These currents are the result of capacitive coupling of the applied PWM voltage to the motor windings. The voltages on the shaft cause a flow of arcing currents through the motor bearings to ground.

I-Probe IP520
I-Probe - IP520 Non-contact current probe 50MHz

The Powertek I-Probe IP520 is a non-contact/non-clamp current probe, allowing fast easy measurement of currents in PCB tracks and cables. It works by placing the insulated tip of the probe onto a PCB track, the current flowing in the track can be observed and measured.
