Explosion hazard
Explosion hazard when measuring ignitable gas / air or
gas / oxygen mixtures
• The gas analyzer may not be used for the measurement of
ignitable gas / air or gas / oxygen mixtures
Caldos27 – sample gas input conditions
Temperature
•
The sample gas dew point should be at least 5 °C below the temperature
throughout the sample gas path. Otherwise a sample gas cooler or
condensate trap is required.
• Water vapor content variations cause volume errors.
Designation of gas connections
The analyzer is operated under atmospheric pressure; the sample gas outlet is
open to atmosphere.
Internal pressure drop:
<
5 hPa at standard flow rate of 60 l/h.
Permissible absolute pressure range:
800
to 1250 hPa.
Operation under lower absolute pressure
(e.g.
at altitudes above 2000 m) on
request.
Gauge pressure in the measuring
chamber:
max. 100
hPa.
Flow rate
Typically 10
to 90 l/h,
minimum 1
l/h
Corrosive gases
If the sample gas contains Cl
2
, HCl, HF, SO
2
, NH
3
, H
2
S or other
corrosive components, the analyzer may only be used if the
sample gas composition has been taken into account by the
manufacturer for the configuration of the analyzer.
Flammable gases
The analyzer is suited for measuring flammable gases in a non-
explosive environment.
Observe the special conditions when measuring flammable
gases, see Special conditions for the measurement of
combustion gases on page 41.
Pressure sensor
The pressure sensor is installed in the gas analyzer at the
factory, see Pressure sensor on page 36.
The pressure sensor is connected to a connection socket via an
FPM tube.
Gas connections
See sections Gas connections Caldos27 (model EL3020) on
page 80and Gas connections Caldos27 (model EL3040) on
page 82.
