Safety barriers are used as separator cirquits without galvanic separation between intrinsically safe and not intrinsically safe electric circuits. Through the integration of a safety barrier, it is possible to install level probes inside hazadrous areas. The safety barrier as well as the level controller must be mounted outside the hazadrous areas.

The safety barriers provide 2 channels.
Each probe will require its own channel.

Probe with 2 electrodes -> 1 x Type 9002/77-280-094-00
Probe with 3 electrodes -> 2 x Type 9002/22-240-024-00
