WARNING
L
The maximum pressure for the measuring device depends on the lowest-rated
element, with regard to pressure, of the selected components, i.e. the process
connection must be taken into consideration in addition to the sensor.
‣
For pressure specifications, see the "Mechanical construction" section.
‣
The measuring device must be operated only within the specified limits!
‣
The Pressure Equipment Directive (2014/68/EU) uses the abbreviation "PS". The
abbreviation "PS" corresponds to the MWP (maximum working pressure) of the
measuring device.
Please refer to the following standards for the pressure values of the flanges that are
permitted at higher temperatures (the lowest value from the derating curves of the device
and selected flange applies in each case):
• pR EN 1092-1: 2005 With regard to its stability-temperature property, the material
1.4435 is identical to 1.4404, which is classed as 13E0 in EN 1092-1 Tab. 18. The
chemical composition of the two materials can be identical.
