9.11 Dual Float Brine Sensors
Smart Sensor Equipped with Intellisense™ Technology
30-0232-D-10B (for Containment Sump) and 30-0232-D-20B (for Fiberglass Tanks)
Description
IMPORTANT:
This float body is the same as the 30-0232-D-10 / D-20 and 30-0232-DH-10 /
DH-20 (DH-XX has a carbon-polymer strip in the bottom). Look at the label to make sure you
have the correct sensor for the applicable function.
The primary function of the Dual Float Brine Sensor is to sense liquid in the brine-filled reservoir of the
interstitial area of a doubled-walled tank. Two (2) float switches are used in the body of the sensor to sense
fluid level changes. The device will cause an alarm condition in the system if the fluid level increases or
decreases more than the normal constant level in the middle between the upper and lower floats. If there is a
break in the cable it will cause an alarm condition in the system.
Since this sensor is not made to sense hydrocarbons it does not use a carbon/polymer strip.
No Carbon/Polymer Strip
The bottom float of the brine sensor will stay in the up position in a normal condition. When the sensor is in
an alarm condition, the upper float will be in a position to cause the alarm condition or the fluid level has
decreased below the bottom float.
