SMS 1145 allows for applications up to 6 bar (87 psi) if suitable sealing materials are used. Please
take this into account when selecting seals and counterparts, as these components can limit the
pressure and temperature range.

Tri-Clamp; clamp connection ISO 2852, DIN 32676, BBS, Neumo BioConnect
The clamp connections are suitable up to a maximum pressure of 16 bar (232 psi). Please observe
the operating limits of the clamp and seal used as they can be over 16 bar (232 psi). The clamp and
seal are not included in the scope of supply.
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.
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.
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
