14.9 Interstitial Hydrocarbon Liquid Sensor with Water Indicator
Smart Sensor Equipped with Intellisense™ Technology
30-0234-HW-01
Description
The primary function of the Interstitial Hydrocarbon Liquid with Water Indicator Sensor is to sense liquid
hydrocarbons and water in the interstitial area of a double-walled tank. The sensor has a carbon/polymer
material that changes its resistance when it is touched by liquid hydrocarbons. The sensor also has a
conductive strip to sense water. This lets the sensor tell the difference between hydrocarbon liquid and
water. If there is a break in the cable it will cause an alarm condition in the system.
