5.1 Compensation of ambient parameters
The TRANSIC111LP can compensate the temperature, pressure of the operating
environment as well as water and CO

content of the background gas.
The typical effect of the error depending on the process pressure is shown in the non-
compensated curve in
Fig. 31 . The error magnitude is smallest at normal ambient air
pressure.

Ambient parameters Standard Activated Remarks
Operating pressure
(process pressure) Standard ambient
parameters:
Pressure: 1 bar(a). Must be activated,
ambient parameters
must be set. The pressure outside the process in
which the measuring device enclosure
is installed should be normal ambient
air pressure. For further information,

Process temperature Automatic, always
active A significant difference between
process gas temperature and the
temperature in the measuring device
enclosure can influence the measured
value result.
