The pressure sensor measures the air pressure inside the housing as
•
standard. As an option, the pressure sensor is connected to a gas port
(flame barrier) via an FPM tube.
If the pressure sensor is connected to a gas port, the yellow plastic
•
screw cap must be screwed out of the connection fittings of the pres-
sure sensor before the gas analyzer is commissioned.
For a precise pressure correction (see page 122) the connection of the
•
pressure sensor and sample gas outlet have to be connected to each
other via a T-piece and short lines. The lines must be as short as possible
or – in the case of a greater length – have a sufficiently large internal
diameter (minimum 10 mm) so that the flow effect is minimized.
If the pressure sensor connection is not connected to the sample gas
•
outlet, the pressure sensor and the sample gas outlet must be on the
same pressure level for an exact pressure correction.
• Pressure sensor working range: p
CAUTION
The pressure sensor connection must not be connected to the sample gas
feed path for the measurement of flammable and corrosive gases.
