Logic Beach offers a line of AC current sensing switches in split-core packages for use in detecting when an AC current exceeds some pre-set current threshold.  These transducers are perfect for detecting when a machine, fan, blower, pump, motor or other load is ON for duty-cycle and/or run-time studies.  Also valuable for detecting over-current conditions and general troubleshooting.
The devices are self-powered and provide a ‘solid-state’ switched output (effectivley an electronic switch) that turns ON (shorts) when the pre-set current threshold is exceeded.  The transducer can readily interface to any of our data loggers via one of the Event or Counter digital inputs.  Three Current Switch models are offered with various threshold ranges and output switching capability.

Multiple conductor loops can be passed through the split-core aperture for increaased sensitivity in detecting lower level currents.  For higher level currents, the transducers can be used with industry standard 5Aac FS output current transformers.

All models are split-core design so that they can be installed without interrupting the circuit, and they are available in three opening sizes.

Model Variations:

Other parts are available with reverse logic (open above threshold) and output ratings. Contact Logic Beach with your special requirements.
