DANGER
Explosion hazard
Explosion hazard when measuring flammable gases and
ignitable gas / air or gas / oxygen mixtures
• The gas analyzer must not be used for measurement of
flammable gases and ignitable gas / air or gas / oxygen
mixtures.
Limas23 – 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.
• The internal temperature of the gas analyzer is at least 10 °C higher than
ambient temperature.
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 sample cell: max. 500 hPa.
Flow rate
20 to 100 l/h
Corrosive gases
The analyzer may not be used for measurement in corrosive
gases. Associated gases, such as chlorine (Cl
2
) or hydrogen
chlorides (such as wet HCl) as well as gases or aerosols
containing chlorine must be cooled or pre-absorbed.
Pressure sensor
The pressure sensor is installed in the gas analyzer as standard,
see
on page 36.
The pressure sensor is connected to the sample gas path or a
connection socket at different positions depending on the
design of the gas analyzer, see
Position and design of the gas
The connection of the pressure sensor is also documented in the
pneumatic diagram included in the device data sheet.
