Sensor housing
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.
In the event of a tube failure, the pressure level inside the sensor housing will rise according to the
operating process pressure. If the user judges that the sensor housing pressure rating/burst pressure
does not provide an adequate safety margin, the device can be fitted with a rupture disk. This
prevents excessively high pressure from forming inside the sensor housing. Therefore, the use of a
rupture disk is strongly recommended in applications involving high gas pressures, and particularly
in applications in which the process pressure is greater than 2/3 of the sensor housing burst
pressure.
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 → 72.
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).
Sensor housing nominal pressure rating and burst pressure
The following sensor housing nominal pressure ratings/burst pressures are only valid for standard
devices and/or devices equipped with closed purge connections (not 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 .
The sensor housing burst pressure refers to a typical internal pressure which is reached prior to
mechanical failure of the sensor housing and which was determined during type testing. The
