9.8 Interstitial Level Sensor
Smart Sensor Equipped with Intellisense™ Technology
30-0230-S Liquid Only Float Sensor (Brass) & 30-0231-S Interstitial Sensor-Float
Switch
Description
The primary function of these sensors is to sense liquid in the interstitial area of a double-walled steel tank
(these sensors are not for use in a double-walled fiberglass tank). A float inside the sensor moves up when
the liquid level increases. The float switch will operate and cause an alarm condition in the controller. The
30-0230-S is made of brass and the 30-0321-S is made of a chemical resistant, non-metallic material.
These sensors can also be used in sumps, fuel dispenser pans and other locations where there is liquid that
could indicate that a leak has occurred. These sensors can also be used together with a vapor sensor (30-
0235-V) to monitor wet wells to make sure that there is a normal liquid level. If there is a break in the cable it
will cause an alarm condition in the system.
