9.3 Permissible Conditions of the sample to be measured
Pressure (absolute)
Standard version: max. 20 bar abs.
with flow measurement: max. 2 bar abs.
for flammable gases: max. 3 bar abs.
Note the deviations of special models!
Gas temperature
At 60 l/h:
- max. 80 °C at 25 °C ambient temperature
- max. 50 °C at 50 °C ambient temperature
- min. -20 °C for version without glass beads
- min. -5 °C for version with glass beads
Dust, aerosols, oil mist,
fluids
Avoid at all costs (e.g. via separator/filter), the option "Protection
against condensate and dust" can prevent impairment of the mea-
suring capability
corrosive gases Only with corrosion-tolerant design and after consulting
Messkonzept
Humidity None should exist below dew point temperature in the sample gas
path, 60°C in the measuring devices and, if necessary, heat the
connection pipe
Water conden-
sate/drops)
Avoid at all costs, the "Protection against condensate and dust"
option can prevent the sensor element from being destroyed by
water

Regarding the introduction of flammable and explosive gases in the devices, please note the instruc-
tions in section 1.2.
