About the 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 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.
