Pressure specifications
For order code for "Sensor version; DSC sensor; measuring tube", option "Mass
steam" , the following applies:
• Only available for measuring devices with the HART communication protocol
• Oil-free or grease-free cleaning is not possible
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 → See 16.6. 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
→ See 16.6. The MWP may be applied at the device for an unlimited period. The MWP can
also be found on the nameplate.
The maximum pressure for the measuring device depends on the lowest-rated
element with regard to pressure.
Note specifications regarding pressure range.
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.
