Hydrocarbon Liquid Sump Sensor
Part #30-3219-12
The Hydrocarbon Liquid Sump Sensor is designed to detect the
presence of liquid hydrocarbons in sumps, dispenser pans and other
locations where the presence of a hydrocarbon liquid could indicate
that a leak has occurred.
The Hydrocarbon Liquid Sump Sensor contains a carbon-polymer
material that changes its resistance when exposed to liquid
hydrocarbons. In the event of a break in the cable, the system will
activate the alarm.
