12 Sensor
Technology Overview
The OPW smart sensors have the ability to monitor all contained
areas of the fuel-storage system: tank interstice, piping sumps, STP
containment sumps, dispenser sumps/pans and monitoring wells.
Sensors connected to the I.S. barrier are automatically detected and
identified by the console.

12.2 IntelliSense™ Technology
This technology allows the Integra and I.S. barrier to automatically
detect sensor connection, sensor type and sensor status. IntelliSense
will minimize user entry error and identify hardware issues with
minimal troubleshooting.
12.3 Multi-drop Installation
The Integra’s internal barrier and optional VSmart Module allows for
the ability to multi-drop the sensors and probes. When using this
installation method; follow the below directions to ensure approved
wiring.
NOTE: Sensors and probes cannot be multi-dropped from the same
I.S. Channel; therefore, you must run sensors and probes to different
channels on the barrier.
NOTE: Seal packs are required with all wiring applications in the
field. Weatherproof junction boxes are REQUIRED with ALL I.S. field
connections.
