Preparation for Installation 33
Caldos27
The pressure sensor is installed in the gas analyzer as standard. It is
connected to a connection port via an FPM hose (see also gas
connections for the models EL3020 (see page 64) and EL3040 (see page
65)).
Information for the proper operation of the pressure sensor
The yellow plastic screw cap must be screwed out of the connectors
of the pressure sensor before the gas analyzer is started up.
The pressure sensor and sample gas outlet must be connected to
each other via a T-piece and short lines to ensure a precise pressure
correction. The lines must be as short as possible or if this is not
practicable, the line must have a sufficiently wide internal diameter
(at least 10 mm) so that the flow effect is minimized.
If the pressure sensor is connected to the sample gas feed path, the
sample gas may not contain any corrosive, flammable or ignitable
components.
If the pressure sensor connection is not connected to the sample gas
outlet, an exact pressure correction is required, so that the pressure
sensor and the sample gas outlet are on the same pressure level.
