MiniFlex® Flexible Sensors

The MiniFlex® 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 MiniFlex® is lightweight. It does not use magnetic cores like standard transformers. The transformation principle is based on an 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 overloads. The sensor assembly is insulated for 1000V CAT III; 600V 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 DMMs, data loggers, oscilloscopes, and power or harmonic meters. 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. The flexible sensor is available in lengths of 6" and 10".
