Absolute Pressure From The Differential Pressure Series - Siemens SITRANS P Operating Instructions Manual

Technical data
13.1 Input
The MAWP value of the pressure transmitter can be lower than the PN value of the mounting
2)
flange and vice versa. To determine the maximum permissible operating pressure and the
maximum permissible test pressure, use the lowest value as reference.

Measured variable
Measuring span (continuous‐
ly adjustable) and maximum
operating pressure (accord‐
ing to 2014/68/EU Pressure
Equipment Directive)
For devices with functional safety, the minimum permissible measuring span is limited by the
1)
spread. Therefore, ensure that the configured spread is no higher than 5:1.
