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
→  89 .
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 →  89 .
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 ceramic process isolating diaphragm (Ceraphire®)
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

Product description Ceraphant PTC31B, PTP31B, PTP33B IO-Link
12 Endress+Hauser
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.
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 Installation
5.1 Mounting dimensions
For dimensions, see the "Mechanical construction" section in the Technical Information.
5.2 Installation conditions
• Moisture must not penetrate the housing when mounting the device, establishing the
electrical connection and during operation.
• Do not clean or touch process isolating diaphragms with hard and/or pointed objects.
• Do not remove process isolating diaphragm protection until shortly before installation.
• Always tighten the cable entry firmly.
• Point the cable and connector downwards where possible to prevent moisture from
entering (e.g. rain or condensation water).
• Protect housing against impact.
• For devices with gauge pressure sensor, the following applies:
NOTICE
If a heated device is cooled in the course of a cleaning process (by cold water, for
example), a vacuum develops for a short time causing moisture to penetrate the
sensor via the pressure compensation element (1).
Device could be destroyed!
‣In the event of this happening, mount the device in such a way that the pressure
compensation element (1) is pointing downwards at an angle or to the side, if possible.

1 Device
2 Shutoff device
Pressure measurement in vapors
For pressure measurement in vapors, use a siphon. The siphon reduces the temperature to
almost ambient temperature. Preferably mount the device with the shutoff device and
siphon below the tapping point.
Advantage:
• defined water column causes only minor/negligible measuring errors and
• only minor/negligible heat effects on the device.
Mounting above the tapping point is also permitted.
Note the max. permitted ambient temperature of the transmitter!
Take the influence of the hydrostatic water column into consideration.

• Always install the device below the lowest measuring point.
• Do not install the device at the following positions:
– In the filling curtain
– In the tank outlet
– in the suction area of a pump
– Or at a point in the tank which could be affected by pressure pulses from the agitator.
• A functional test can be carried out more easily if you mount the device downstream
from a shutoff device.

5.5 Mounting instructions for oxygen applications
Oxygen and other gases can react explosively to oils, grease and plastics, such that, among
other things, the following precautions must be taken:
• All components of the system, such as measuring devices, must be cleaned in accordance
with the BAM requirements.
• Dependent on the materials used, a certain maximum temperature and a maximum
pressure for oxygen applications must not be exceeded.
• The following table lists devices (devices only, not accessories or enclosed accessories),
which are suitable for gaseous oxygen applications.

5.6 Post-installation check
 Is the device undamaged (visual inspection)?

Does the device comply with the measuring point specifications?
For example:
• Process temperature
• Process pressure
• Ambient temperature range
• Measuring range
 Are the measuring point identification and labeling correct (visual inspection)?
 Is the device adequately protected against precipitation and direct sunlight?
 Are the securing screws tightened securely?
 Is the pressure compensation element pointing downwards at an angle or to the side?
 To prevent moisture from penetrating, ensure that the connecting cables/plugs are pointing downwards.
