TFP Series chemical resistant Leak Detect Sensor

Strong chemical resistance!

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. With a Teflon (PFA) casing and cable (FEP) the teflon unit is highly resistive to harsh chemicals.

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