WARNING
The maximum pressure for the device depends on the lowest-rated component with
regard to pressure (components are: process connection, optional mounted parts or
accessories).
‣
Only operate the device within the specified limits for the components!
‣
MWP (Maximum Working Pressure): The MWP is specified 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. For flanges, refer
to the following standards for the permitted pressure values at higher temperatures:
EN 1092-1 (with regard to their stability/temperature property, the materials 1.4435
and 1.4404 are grouped together under EN 1092-1; the chemical composition of the
two materials can be identical), ASME B16.5, JIS B2220 (the latest version of the
standard applies in each case). MWP data that deviate from this are provided in the
relevant sections of the Technical Information.
‣
The Pressure Equipment Directive (2014/68/EU) uses the abbreviation PS . This
corresponds to the maximum working pressure (MWP) of the device.
The following tables show the dependencies between the seal material, process
temperature (T
P
) and process pressure range for each process connection that can be
selected for the antenna used.
