Item Term/abbreviation Explanation
1 OPL The OPL (over pressure limit = sensor overload limit) for the measuring device depends on the lowest-rated element,
with regard to pressure, of the selected components, i.e. the process connection has to be taken into consideration in
addition to the measuring cell. Also observe pressure-temperature dependency. For the relevant standards and
additional notes see the "Pressure specifications" section →  55.
The OPL may only be applied for a limited period of time.
2 MWP The MWP (maximum working pressure) for the sensors depends on the lowest-rated element, with regard to
pressure, of the selected components, i.e. the process connection has to be taken into consideration in addition to the
measuring cell. Also observe pressure-temperature dependency. For the relevant standards and additional notes see
the "Pressure specifications" section →  55.
The MWP may be applied at the device for an unlimited period.
The MWP can also be found on the nameplate.

p
A0020465
1 Air pressure (gauge pressure sensors)
2 Ceramic substrate
3 Electrodes
4 Ceramic process isolating diaphragm
The ceramic sensor is an oil-free sensor, i.e. the process pressure acts directly on the robust ceramic
process isolating diaphragm and causes it to deflect. A pressure-dependent change in capacitance is
measured at the electrodes of the ceramic substrate and the process isolating diaphragm. The
measuring range is determined by the thickness of the ceramic process isolating diaphragm.
Advantages:
• Guaranteed overload resistance up to 40 times the nominal pressure (see "OPL" column in table)
→  14)
• The ultrapure 99.9% ceramic (Ceraphire®, see also "www.endress.com/ceraphire") ensures:
– Extremely high chemical durability
– High mechanical durability
• Suitable for vacuums
• Secondary containment for enhanced integrity
• Process temperatures up to 150 °C (302 °F)

4 Metal process isolating diaphragm
PMP71
The process pressure deflects the metal process isolating diaphragm of the sensor and a fill fluid
transfers the pressure to a Wheatstone bridge (semiconductor technology). The pressure-dependent
change in the bridge output voltage is measured and evaluated.
Advantages:
• Can be used for process pressures up to 700 bar (10 500 psi)
• High long-term stability
• Guaranteed overload resistance up to 4 times the nominal pressure
• Secondary containment for enhanced integrity
• Significantly reduced thermal effect e.g. compared to diaphragm seal systems with capillaries
PMP75
The operating pressure acts on the process isolating diaphragm of the diaphragm seal and is
transferred to the process isolating diaphragm of the sensor by a diaphragm seal fill fluid. The
process isolating diaphragm is deflected and a fill fluid transfers the pressure to a resistance
measuring bridge. The pressure-dependent change in the bridge output voltage is measured and
evaluated.
Advantages:
• Depending on the version, can be used for process pressures up to 400 bar (6 000 psi) and for
extreme process temperatures
• High long-term stability
• Guaranteed overload resistance up to 4 times the nominal pressure
• Secondary containment for enhanced integrity
