Interstitial Level Sensor Float Switch
OPW P/N: 30-0231-S
Interstitial Level Sensors are used primarily in the interstitial area of a
steel double-walled tank. The sensor contains a float switch that
activates in the presence of a liquid. The sensor is constructed from
chemical-resistant non-metallic material. It can also be used in
sumps, dispenser pans and other locations where the presence of a
liquid could indicate that a leak has occurred. In the event of a break
in the cable, the system will activate the alarm.
This technology allows the Integra and I.S. barrier to automatically
detect sensor connection, sensor type and sensor status, will
minimize user entry error and identify hardware issues with minimal
troubleshooting.
