54 AO2000 CONTINUOUS GAS ANALYZERS | OI/AO2000-EN REV. B
Limas11 IR, Limas21 UV: Preparation for installation
Installation site
Ambient temperature
During operation with analyzer module installed in a system housing
+5 to +45 °C without electronics module
+5 to +45 °C with electronics module or only with power supply
+5 to +40 °C with electronics module, if I/O modules are installed, or
only with power supply
Vibrations/shocks
max. ±0.04 mm at 5 to 55 Hz; 0.5 g at 55 to 150 Hz
Sample gas
Sample gas inlet conditions
Temperature The dew point of the sample gas must be at least 5 °C
lower than the lowest ambient temperature in the overall
sample gas path. Otherwise, a sample gas cooler or con-
densate trap is required.
Pressure The analyzer module is operated under atmospheric pres-
sure; the sample gas outlet is open to atmosphere. Inter-
nal pressure drop < 5 hPa with standard flow rate 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. Overpressure in the sample cell
max. 500 hPa.
Flow 20 to 100 l/h
Remark: Sample gas temperature, pressure and flow rate should be main-
tained constant to such a degree that the fluctuation influence on the accu-
racy of measurement is acceptable (see also chapter "Analyzer module oper-
ating data" (see page 346)).
