MiniFlex® HF Flexible Sensors

The High Frequency MiniFlex® HF is a compact flexible AC current transformer composed of a flexible sensor and an electronic module. The flexible sensor permits measurements on conductors where standard clamp-on probes could not be used. In particular, it can be installed in confined spaces, places where access is difficult, or even wrapped around irregular shapes.

The High Frequency MiniFlex® HF, with a bandwidth frequency from 5 Hz to 1 MHz, is perfect to connect to any oscilloscope with BNC input to analyze complex-shaped current and transient present in electronic power supplies, welding stations, etc. It presents virtually no load to the system under test and cannot be damaged by overloads. The sensor assembly is insulated for 1000 V CAT III; 600 V CAT IV. The MiniFlex® meets EN 61010 and is CE marked. It has an mV output proportional to the current measured for direct readings on DMM, data loggers or oscilloscopes,. TRMS measurements are taken when connected to a TRMS meter. The MiniFlex® is insensitive to DC currents and only the AC component of the measured signal is measured.
