LEM is offering its LEM~Flex III AC current measurement probe, which permits safe, accurate and non-intrusive measurement. This is even possible in applications that may be inaccessible with standard clamp-on probes and instruments.

Based on LEM~Flex, LEM's original flexible current probe which was four times lighter than standard clamp on probes, this probe offers an extended battery life up to 400 hours and an AC-coupled output.

A number of versions are available: the RR3020 type with 4 mm safety plugs for direct connection to multimeters, recorders and data loggers, without additional leads. The RR3030 type has a BNC connector for connection to oscilloscopes, recorders and data loggers. The third version, the RR3120 has the same specification as the RR3020, with a 1 mV output.

These probes provide an isolated linear output voltage, which is a proportional replica of the input waveforms with three user selectable input current ranges of 30, 300 or 3000 A. The flexible measuring head offers a 175 mm diameter window and 2 m connecting cable, the operating temperature range is from -20°C to 90°C. The measurement accuracy is ±1% of range and the bandwidth is 10 Hz for the RR3030 type and 10 Hz to 20 kHz for the RR3020 type. The range complies with EN61010-1 600 V CAT III Pollution degree 2 for input and output circuits and EMC standard EN 61326.
