An overview of the pressure-temperature ratings for the process connections is
provided in the "Technical Information" document
The sensor housing is filled with dry nitrogen gas and protects the electronics and
mechanics inside.
If a measuring tube fails (e.g. due to process characteristics like corrosive or abrasive
fluids), the fluid will initially be contained by the sensor housing.
If the sensor is to be purged with gas (gas detection), it should be equipped with purge
connections.
Do not open the purge connections unless the containment can be filled immediately
with a dry, inert gas. Use only low pressure to purge. Maximum pressure:
5 bar (72.5 psi).
