CWT Mini - Rogowski coil current sensor Miniature wideband current probe for current measurement
The CWT Miniature current probes utilize a Rogowski Coil sensor thin enough (typical cross section 3.5mm) to fit in very confined sPACes - often between the legs of a semiconductor power switching device. With high frequency bandwidths up to 20MHz, the CWT miniature Rogowski coil is ideal for measuring switching transients or pulsed currents starting at 300mA up to 300kA in power electronic equipment. The CWT miniature Rogowski probe is aclip around flexible coilcurrent probe based on the Rogowski principle to achieve high bandwidth measurement and faithful conversion of current to voltage, intended for use with oscilloscopes, data loggers, power meters and power analyzers. Available with a 100mm or 200mm length clip-around coil, ensuring easy current monitoring even where access is limited. |
