Pressure sensor
The pressure sensor is connected to the Pos. 1 terminal if
the internal gas lines are designed as stainless steel pipes,
or if the ‘Pressure sensor connected outside by hose’ option
is ordered.

Note
• If the internal gas lines ares designed as hoses, the pressure sensor (standard, not for the ‘pressure sensor connected to outside
by hose’ option), and the oxygen sensor (option) are internally connected as follows:
– In the output of measuring cell 1, for one measuring cell and for two measuring cells with separate gas paths.
– In the output of measuring cell 2 for two measuring cells in a series.
– The second oxygen sensor (option for version with separate gas paths) is connected in the outlet of sample cell 2.
• If the internal gas lines are designed as stainless steel pipes, the oxygen sensor and the version with separated gas paths are not
possible.
