NOTE
A pressure sensor cannot be installed in the ZO23 and Fidas24 gas
analyzers.
The pressure sensor is installed in the gas analyzer as standard.
Depending on the design of the gas analyzer, it is internally connected as
follows (see also Gas Connections for the models EL3020 (see page 42)
and EL3040 (see page 44)):

Internal gas lines executed as flexible tubes:

Pressure sensor in the outlet of sample cell 1 with one sample
cell and with separate gas feed paths

Pressure sensor in the outlet of sample cell 2 with two sample
cells in series

Internal gas lines are executed as stainless steel pipes:

Pressure sensor is connected to a connection port via an FPM
tube
The connection of the pressure sensor is also documented in the
pneumatic diagram contained in the analyzer data sheet.
The pressure sensor is installed in the gas analyzer as standard. It is
internally connected in the outlet of the sample cell (see also gas
connections for the models EL3020 (see page 54) and EL3040 (see page
55)).
The pressure sensor is installed in the gas analyzer as an option. It is
connected to a connection port via an FPM hose (see also gas
connections for the models EL3020 (see page 58) and EL3040 (see page
59)).
With measurements in suppressed measuring ranges, the connection of
the pressure sensor and the sample gas outlet are to be connected to
each other via a T-joint and short lines.
Particular care should be taken to ensure that the gas discharge line is as
short as possible. If this is not practicable, the line must have a
sufficiently wide internal diameter (at least 10 mm).
The pressure sensor is installed in the gas analyzer as an option. It is
connected to a connection port via an FPM hose (see also gas
connections for the model EL3020 (see page 60)).
