An overview of the pressure-temperature ratings for the process connections is
provided in the "Technical Information" document
Secondary containment
For the Standard version with the temperature range –50 to +150 °C (–58 to +302 °F), the
sensor housing is filled with dry nitrogen gas and protects the electronics and mechanics
inside.
For all other temperature versions the sensor housing is filled with dry inert gas.
The following secondary containment pressure ratings/burst pressures are only valid for
standard devices and/or devices equipped with closed purge connections (never opened/as
delivered).
If a device fitted with purge connections (order code for "Sensor option", option
CH
"Purge
connection") is connected to the purge system, the maximum nominal pressure is
determined by the purge system itself or by the device, depending on which component
has the lower nominal pressure classification.
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
→ 241.
The secondary containment burst pressure refers to a typical internal pressure achieved
prior to mechanical failure of the secondary containment as determined during type
testing. The corresponding type test declaration can be ordered with the device (order code
for "Additional approval", option
LN
"Type test containment").

If a measuring tube fails (e.g. due to process characteristics like corrosive or abrasive
fluids), the fluid will be contained by the secondary containment.
If there is a need to drain the leaking medium into a discharge device, the sensor should be
fitted with a rupture disk. Connect the discharge to the additional threaded connection .
