9.10 Dual Float Non-Discriminating Sensors
Smart Sensor Equipped with Intellisense™ Technology
30-0232-D-10 Dispenser Sump Sensor & 30-0232-D-20 STP Sump Sensor
Description
IMPORTANT:
This float body is the same as the 30-0232-D-10B / D-20B 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 Non-Discriminating Sensor is to sense liquid hydrocarbons and water
in sumps, fuel dispenser pans and other locations where there is liquid that could indicate that a leak has
occurred. This sensor looks almost the same as the 30-0232-DH-XX but is non-discriminating. This means
that the sensor does
not
use a carbon/polymer material to sense liquid hydrocarbons. Use the D-10 on fuel
dispenser pans and transition sumps. Use the D-20 in tank sump pits. Two (2) float switches are used in the
body of the sensor to sense low and high liquid levels. If there is a break in the cable it will cause an alarm
condition in the system.
