Pressure-temperature
ratings
An overview of the pressure-temperature ratings for the process connections is
provided in the "Technical Information" document
Nominal pressure of sensor The following overpressure resistance values apply to the sensor shaft in the event of a
membrane rupture:
Sensor version; DSC sensor; measuring tube Overpressure, sensor shaft
in [bar a]
Volume 200
Volume high-temperature 200
Mass (integrated temperature measurement) 200
Mass steam (integrated pressure/temperature measurement)
Mass gas/liquid (integrated pressure/temperature measurement)
200
Pressure specifications The "mass" sensor version (integrated pressure/temperature measurement) is
available only for measuring devices in the HART communication mode.
The OPL (over pressure limit = sensor overload limit) for the measuring device depends on
the lowest-rated element, with regard to pressure, of the selected components, i.e. the
process connection has to be taken into consideration in addition to the measuring cell.
Also observe pressure-temperature dependency. For the appropriate standards and further
information →  186. The OPL may only be applied for a limited period of time.
The MWP (maximum working pressure) for the sensors depends on the lowest-rated
element, with regard to pressure, of the selected components, i.e. the process connection
has to be taken into consideration in addition to the measuring cell. Also observe pressure-
temperature dependency. For the appropriate standards and further information
→  186. The MWP may be applied at the device for an unlimited period. The MWP can
also be found on the nameplate.

WARNING
The maximum pressure for the measuring device depends on the lowest-rated
element with regard to pressure.
‣
Note specifications regarding pressure range→  186.
‣
The Pressure Equipment Directive (2014/68/EU) uses the abbreviation "PS". The
abbreviation "PS" corresponds to the MWP of the device.
‣
MWP: The MWP is indicated on the nameplate. This value refers to a reference
temperature of +20 °C (+68°F) and may be applied to the device for an unlimited time.
Note temperature dependence of MWP.
‣
OPL: The test pressure corresponds to the over pressure limit of the sensor and may be
applied only temporarily to ensure that the measurement is within the specifications
and no permanent damage occurs. In the case of sensor range and process connection
combinations where the OPL of the process connection is less than the nominal value
of the sensor, the device is set at the factory, at the very maximum, to the OPL value of
the process connection. If using the entire sensor range, select a process connection
with a higher OPL value.
