3.1.2 Temperature conditions
The TRANSIC111LP probe contains a temperature sensor. This sensor measures the
temperature of the sample gas and is used for temperature compensation of the gas to be
measured.
Observe the temperature conditions in the different variants, see “TRANSIC111LP vari-
ants”, page 14.
In the in-situ version of TRANSIC111LP, (see “Flange mounted TRANSIC111LP-A/-D/-F/-G/
-H/-I/-J/-K”, page 14), the temperature probe and the measuring device enclosure are
connected heat-conductive. Thus, the ambient temperature affects the measured value of
the temperature probe. This causes measurement errors because the measured
temperature value used in compensation deviates slightly from the actual process gas
temperature.
Further information on the operating temperature range can be found in “Ambient condi-
tions”, page 101.

NOTICE: Specify suitable seals when ordering
▸ Changing the seals later is work intensive and can only be done by SICK.
WARNING: Toxic gases escaping
Incorrect sealing material leads to leaks.
▸ Ensure the seal used is compatible with the temperature of the process gas in your
application.
Only use lubricants compatible with oxygen when installing seals.
