The optical level switch has been designed for use in level monitoring applications for the control of the liquid presence/absence and can be suitable for a lot of applications due to the wide chemical compatibility assured by the technology of the fused glass dome with the stainless steel body.
The switch has no moving parts, thus it is particularly suited for monitoring critical media where high reliability is needed.
For minimum / maximum level detection the switch must be mounted at the desired height and gives an alarm when low (or high) liquid level is detected.
Other typical applications are pump dry run protection or leakage detection application where the sensor must be mounted in the point where the liquid has to be detected and gives an alarm when the liquid is absent or present.

operation mode: detect liquid presence with contact
body materials: Stainless Steel with Glass sensible dome
