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
→  38.
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 →  38.
The MWP may be applied at the device for an unlimited period.
The MWP can also be found on the nameplate.

Example
• Sensor:10 bar (150 psi)
• Upper range value (URL) = 10 bar (150 psi)
Turn down (TD):
• Calibrated/adjusted span:
0 to 5 bar (0 to 75 psi)
• Lower range value (LRV) = 0 bar (0 psi)
• Upper range value (URV) = 5 bar (75 psi)
TD = URL
|URV - LRV|
TD = 10 bar (150 psi) = 2
|5 bar (75 psi) - 0 bar (0 psi)|
In this example, the TD is 2:1.
This span is based on the zero point.

3.2 Function
3.2.1 Calculating the pressure
Devices with metallic process isolating diaphragm
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.

5.1 Mounting dimensions
For dimensions, see the "Mechanical construction" section in the Technical Information.
5.2 Installation conditions
• No moisture may enter the housing when installing or operating the device, or when
establishing the electrical connection.
• Do not remove the protection cap of the M12 plug terminal until shortly before the
electrical connection.
• Do not clean or touch process isolating diaphragms with hard and/or pointed objects.
• Do not remove the protector on the process isolating diaphragm until just before
installation.
• Always firmly tighten the cable entry.
• Point the cable and connector downwards where possible to prevent moisture from
entering (e.g. rain or condensation water).
• The following instruction applies for devices with a gauge pressure sensor and M12 plug
or valve plug:
NOTICE
If a heated device is cooled during the cleaning process (e.g. by cold water), a vacuum
develops for a short time, whereby moisture can penetrate the sensor through the
pressure compensation element (1).
Device could be destroyed!
‣In this case, mount the device with the pressure compensation element (1) pointing
diagonally downwards where possible or to the side.
