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
Table 9.3: Properties of the sample gas.
Regarding the introduction of flammable and explosive gases in the devices, please note the instruc-
tions in section 1.3.
