WARNING
The maximum pressure for the measuring device is dependent on the lowest-rated element,
with regard to pressure, of the selected components. This means that it is necessary to pay
attention to the process connection as well as 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.
