In the sample gas path if pipes are used as the internal gas
lines.
Connected to an external port via a FPM / FKM pipe if tubing
is used for the internal gas lines (see Figures 3-6 to 3-9,
pages 3-6 to 3-9 and pneumatic diagram in the analyzer
data sheet).

Pressure Sensor
Connection
For measurements in suppressed measurement ranges, the
pressure sensor port and the sample gas outlet must be
connected via a tee and short lines. Please observe that the
exhaust line is kept as short as possible or, if longer lines are
necessary, that the inner diameter is sufficiently large (
≥
10 mm).
Notes for Proper
Pressure Sensor
Operation
Please observe the following notes for the proper operation of the pressure
sensor:
•
Remove the yellow plug from the pressure sensor port before start-up of the
analyzer module.
•
For a precise pressure correction, the pressure sensor port must be connected
to the sample gas outlet via a tee and short lines. To reduce the flow effect, the
lines must be kept as short as possible or, if longer lines are necessary, the inner
diameter must be sufficiently large (
≥
10 mm).
•
If the pressure sensor is connected to the sample gas path, the sample gas
must not contain corrosive components nor may it be flammable or at risk of
explosion.
•
If the pressure sensor port is not connected to the sample gas outlet, precise
pressure correction can only take place if the pressure sensor and the sample
gas outlet are on the same pressure level.
Further information about pressure correction can be found in sections “Air
Pressure Correction”, page 9-28, and “Air Pressure Value Correction”, page 9-29.
