Note
• The oxygen sensor is not possible in combination with Caldos27
• 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 cells 2 for two measuring cells in series.
• If the internal gas lines are designed as stainless steel pipes, the version with separate gas paths is not possible.
Supplementary information
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.
