• Please note that the housing can no longer assume a secondary containment function if a rupture
disk is used.
• It is not permitted to open the connections or remove the rupture disk.

Purge and pressure monitoring connections
The sensor housing protects the inner electronics and mechanics and is filled with dry nitrogen.
Beyond that, up to a specified measuring pressure it additionally serves as secondary containment.

Warning!
For a process pressure above the specified containment pressure, the housing does not serve as an
additional secondary containment. In case a danger of measuring tube failure exists due to process
characteristics, e.g. with corrosive process fluids, we recommend the use of sensors whose housing
is equipped with special pressure monitoring connections (ordering option). With the help of these
connections, fluid collected in the housing in the event of tube failure can be drained off. This
diminishes the danger of mechanical overload of the housing, which could lead to a housing failure
and accordingly is connected with an increased danger potential. These connections can also be
used for gas purging (gas detection).

The following instructions apply to handling sensors with purge or pressure monitoring connections:
• Do not open the purge connections unless the containment can be filled immediately with a dry
• Do not open the purge connections unless the containment can be filled immediately with a dry
inert gas.
• Use only low gauge pressure to purge. Maximum pressure 5 bar (73 psi).

Data storage device (HistoROM)
The term HistoROM refers to various types of data storage modules on which process and measuring
device data are stored. By plugging and unplugging such modules, device configurations can be
duplicated onto other measuring devices to cite just one example.

HistoROM/S–DAT (sensor–DAT)
The S-DAT is an exchangeable data storage device in which all sensor relevant parameters are
stored, i.e., diameter, serial number, calibration factor, zero point.
