Operating conditions (process)
Process temperature range PMC131
• –20 to +100 °C
• Devices for oxygen application: −10 to +60 °C
(Version "S" for feature 30 "Sensor gasket")
PMP131
–25 to +70 °C
PMP135
–25 to +100 °C (+135 °C for max. 1 hour)
Extreme jumps in temperature can result in temporary measuring errors. Temperature compensation takes
effect after several minutes. Internal temperature compensation is faster the smaller the temperature jump and
the longer the time interval.

Pressure specifications • The MWP (maximum working pressure) of the device is specified on the nameplate. It depends on the
weakest element, with regard to pressure, of the selected components. See the following sections:
– → Page 18 ff, "Ordering information" section, feature 50 "Measuring range; MWP; Nominal value; OPL"
or "Sensor range; MWP; OPL".
– → Page 12 ff, "Mechanical construction" section.
The MWP specification on the nameplate is based on a reference temperature of +20 °C and can be present
over an unlimited period of time.
• The test pressure corresponds to the overload limit of the measuring device (Over Pressure Limit OPL) and
must only be present for a limited period of time.
