Dual-Float Brine Sensor (D-20B)
Part No. 30-0232-D-20B
Dual-Float Brine Sensor (D-20B)
The Dual Float Brine Sensor (D-20B) is very similar to the 30-0232-
D-20, but unlike the other dual float sensors it measures a level of
liquid that is already present in the tank. The bottom float of the brine
sensor will remain in the up position in a normal condition. When in
alarm, the sensor will have either triggered the upper float or the level
has dropped below the bottom float.
*NOTE: Maximum Wiring Length is the maximum length of cable to
be used to connect all sensors on an individual channel. This length
includes run of cable from I.S. Barrier to each sensor board in the
string.
