Type 31160-NI Ex Proof Standard Magnetic Switch Magnetic Level Indicator

The magnetic switch is mounted outside of the float chamber opposite to the indication rail. The switching logic can be reversed by inverting the switch module with cable-exit upwards or by installing the switch module adjacent to the indication rail where technically authorised.

The magnet inside the float activates the reed switch, when the liquid in the float chamber reaches that level. The switch must be connected with a certified energy limiting device (e.g. Zener barrier) installed in a safe area. This device guarantees the electrical limit values specified below, including the cable. Please refer to the safety guidelines.
