gas-lab
Q1
The parameterisation of the evaluation computer defines which gas has to be
connected to which inlet. The process gas is assigned to path 1 and the internal
calibration gas (ultra-pure methane) to path 2. Nitrogen and further calibration
gases are injected via path 3 for performing the basic calibration. The test gas
can either be injected via path 1 or 3.

Not only the sensor housing is installed on the mounting plate, but also
regulators for the inlet pressure of the different gases to be injected, safety shut-
off and safety relief valves as well as the EEx-e junction box for the
interconnecting cables (voltage supply, data link to the evaluation computer).
