Combo Single Level / Hydrocarbon Liquid Sump
Sensor
Part #30-3224
This sensor is made from the Hydrocarbon Liquid Sump Sensor (30-
3219-12) with an Interstitial Level Sensor (30-3221-1A) 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.
This sensor can be used to monitor wet wells to ensure that a liquid is
normally present. In the event of a break in the cable, the system will
activate the alarm.

*Maximum Wiring Length is the maximum length of cable to be used
to connect all sensors on an individual channel. The length includes
run of cable from VSmart to each sensor board in the string.
