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.
Sensor housing nominal pressure rating and burst pressure
The secondary containment does not have a pressure rating classification.
Reference value for the pressure loading capacity of the sensor housing: 16 bar (232 psi)
If the device is fitted with a rupture disk (order code for "Sensor option", option CA "Rupture
disk"), the rupture disk trigger pressure is decisive for the maximum nominal pressure .
