Interstitial Optical Liquid Sensor
Part #30-3223
The Interstitial Optical Liquid Sensor is used primarily to monitor the
interstitial area of double-walled tanks. This sensor incorporates a
long-life optical prism and can also be used in sumps, dispenser pans
and other locations where the presence of a liquid could indicate that a
leak has occurred.
The sensor does not differentiate between water and hydrocarbon
liquid. In the event of a break in the cable, the system will activate the
alarm.
