Combo Dual-Level/Hydrocarbon Liquid Sump
Sensor
OPW P/N: 30-3225
Combo Dual-Level/Hydrocarbon Liquid Sump Sensor
This sensor is made from the Hydrocarbon Liquid Sump Sensor (30-
3219-12) with a Dual-Level Reservoir Sensor (30-3221-2) clipped to
its side. The combination sensor is designed to detect the presence
of liquid hydrocarbons and water in sumps, dispenser pans and other
locations where the presence of a liquid could indicate that a leak has
occurred.
The sensor contains a carbon/polymer material that changes
resistance when exposed to liquid hydrocarbons. The level sensor
portion simply clips onto the hydrocarbon sensor and can be
positioned at any desired height to activate in the presence of liquid.
