LUP Series compact Leak Detect Sensor

Quantity:
 

These units usually sit in a drip pan or similar location where people want to know if there is a leak. If they end up in the thinnest pool of liquid they will alarm. They use a detector looking at an LED and if that light path gets altered at all then it knows there is a liquid there. With that it will detect any liquid as long as it is not exposed to excessive high or low temperatures.

However these units are not rated to operate in a hazardous potential explosive environment.
