FQ-RCT01 Flexible Rogowski type clamp on AC measurement current Probe

flexible current probe

The GFUVE FQ-RCT01 Flexible AC Current Probe is composed of a flexible sensor and an electronic module. The flexible sensor probe permits measurements on conductors where standard clamp-on probes cannot be used. In particular, it can be installed in tight spaces, around cable bundles, around wide or large bus bars, or even wrapped around irregular shapes. The Shape Memory feature enables the user to pre-shape the sensor probe before inserting it between or around conductors. .



This feature facilitates positioning the sensor around the conductor, enhances user safety, and alleviates the drooping effect associated with other flexible sensors.This Flexible AC Current Probe is lightweight and does not use magnetic cores like standard transformers. The transformation principle is based on air core. It presents virtually no load to the system under test, has a low phase shift and excellent frequency response, and cannot be damaged by current overloads. The sensor assembly is waterproof and insulated for 1000V working voltage. Conforms to EN 61010, 1000V CAT III with CE marked.
