Hydrocarbon Vapor Sensor
Part No. 30-3222
The Hydrocarbon Vapor Sensor is designed to detect hydrocarbon
vapors in dry monitoring wells. The presence of these vapors could
indicate a potentially dangerous leak that could lead to safety and
environmental problems.
The sensor is made from a long-life resistive element that increases
dramatically in resistance in the presence of hydrocarbon vapors. After
the vapors have dissipated, the sensor returns to normal and is ready
to detect hydrocarbon vapors again. This process could take up to 30
minutes depending on the saturation factor. In the event of a break in
the cable or any sensor malfunctions, the system will activate the
alarm.
Hydrocarbon Vapor Sensor
Installation Procedure
1. Check Dry Monitoring Wells for vapors before installing.
2. Mount Sensor close to the top, above the water level, if
applicable.
3. If sensor is submerged in water it will not function.
*Maximum Wiring Length is the maximum length of cable to be used
to connect all sensors on an individual channel. The length includes
the run of cable from the VSmart Module to each sensor board in
the string.
