Process pressure range

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.
‣
For pressure specifications, see the "Mechanical construction" section.
‣
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.
Refer to the following standards for the permitted pressure values of the flanges at higher
temperatures:
• pR EN 1092-1: 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.
• ASME B 16.5
• JIS B 2220
In each case, the lowest value from the derating curves of the device and the selected
flange applies.
Devices with CRN approval: maximum 90 bar (1 305 psi) for devices with a pipe
extension. Information on the Endress+Hauser website:

1 Permitted pressure rating when the "100 bar (1 450 psi)" option is selected. For exceptions, see the "Process
connections" section. Canadian CRN approval: The maximum permitted process pressure is limited to
90 bar (1 305 psi) only in combination with the CRN approval. More details on the maximum pressure values
are available in the download area of the product page under "www.endress.com".
