Class 1, Division 2
This installation is used to power down the Sigma Sampler in the event of a combustible gas presence at the sampler unit.
The gas monitoring equipment is made up of three main components.
1) The Sampler Gas Detector (#A00563)
2) The Interface Block (#A00562)
3) The Installation Kit (sampler lid plus gas detector and battery tray)(#A00564)
In the presence of 10% LEL combustible gas the gas detector will power down both the sampler and the gas detector. To re-start, remove the sampler to above ground and power on the gas detector.
Note: The 10% LEL combustible alarm is relative to a Methane calibration. Other combustible gases will also initiate an equipment shutdown.
