Chemical tolerance
The TRANSIC151LP contains several seals. Two material options are available for the seals:
– FKM (fluoro elastomer)
– Kalrez
®
Spectrum 6375 (perfluor elastomer)
3.1.2
Temperature conditions
The TRANSIC151LP probe contains a temperature probe. This measures the sample gas
temperature. Changes are compensated metrologically.
Observe the temperature conditions in the different variants,
The temperature probe and the 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 devi-
ates slightly from the actual process gas temperature. Avoid heat build-up through direct
sunlight: Use the optional weather hood when appropriate, (
).
Further information on the operating temperature range of the measuring device,
NOTE:
Specify suitable seals when ordering
▸
Changing the seals later is work intensive and can only be done by SICK.
WARNING:
Hazard through incorrect sealing material
Incorrect sealing material can revoke zone separation.
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.
NOTE:
The temperature gradient between process and surroundings
influences the measured value.
▸
The ambient temperature of the measuring device enclosure at the installation
location should correspond to the process temperature.
