Information for the safe and correct operation of the
pressure sensor
DANGER
Explosion hazard
Explosion hazard when measuring flammable or ignitable
gases with the pressure sensor.
• The pressure sensor must not be connected to the sample
gas path if the sample gas contains flammable or ignitable
components.
NOTICE
Damage to the pressure sensor
Damage to the pressure sensor by corrosive gases.
• For the measurement of corrosive gases, the terminal of
the pressure sensor must not be connected to the sample
gas path.
• Prior to the commissioning of the gas analyzer, the yellow
plastic screw plug has to be screwed out of the connectors
of the pressure sensor.
• For a precise pressure correction, the connection of the
pressure sensor and sample gas outlet should be connected
with 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 inside diameter
(min. 10 mm) so that the flow effect is minimized.
If the pressure sensor is not connected to the sample gas
output, the pressure sensor and sample gas output must be
at the same level of pressure.
• Pressure sensor working range:
p
abs
= 600 to 1250 hPa.
