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 dimi-
nishes 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
inert gas.
• Use only low gauge pressure to purge. Maximum pressure 5 bar.

Data storage device (DAT)
At Hauser, 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.
6.5.1
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.
6.5.2
HistoROM/T-DAT (transmitter-DAT)
The T-DAT is an exchangeable data storage device in which all transmitter parameters and settings
are stored.
Storing of specific parameter settings from the EEPROM to the T-DAT and vice versa has to be car-
ried out by the user. Detailed instructions regarding this can be found in the handbook “Description
of Device Functions”.
