WARNING
L
The maximum pressure for the device depends on the lowest-rated element, with
regard to pressure, of the selected component. This means that it is necessary to pay
attention to the process connection as well as the sensor.
‣
Pressure specifications, see the associated Technical Information.
‣
Only operate the device 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 device.
