Ceramic sensor
The system pressure acts directly on therugged ceramic diaphragm of the pressure
sensor deflecting it by a maximum of 0.025
mm. A pressure-proportional change in thecapacitance is measured by the electrodeson the ceramic substrate and diaphragm.
The measuring range is determined by the
thickness of the ceramic diaphragm.

Metal sensor
The process pressure deflects theseparating diaphragm with a filling liquidtransmitting the pressure to a resistancebridge. The bridge output voltage, which is
proportional to pressure, is then measured
and processed.

PVDF adapter

For instruments with PVDF adapter, a maximum torque of 7 Nm is permitted. The threadconnection may become loose at high temperatures and pressures. This means that the
integrity of the thread must be checked regularly and may need to be tightened using
the torque given above. Teflon tape is recommended for sealing with the ½ NPT thread.

Mounting the PMP 731

The PMP 731 with metallic sensor is available in the following versions:• with flush-mounted diaphragm or• with adapter (screwed on or welded in) and internal diaphragm.
A seal is enclosed appropriate to the material used and version.

Level measurement

The use of temperature spacers is
recommended for continuous extreme
product temperatures.
• Note when mounting that thetemperature spacer increases the
maximum height by 100 mm.
• Due to the hydrostatic column in thetemperature spacer, the increased
height also causes a zero point shift ofapprox. 10 mbar.
See Chapter 5.1, pages 26 and 27 for
information concerning position
calibration (display only) or zero-point
correction.

For level measurement the Cerabar S must
always be installed below the lowest
measuring point.
• The instrument should not be installed
within the flow of material, in the outletof the tank or at a place in the tankwhere pressure pulses from agitator
blades may occur.
• Calibration and function testing areeasier to carry out if the Cerabar S ismounted downstream from a shut-off
valve.

The Cerabar S with diaphragm seal isscrewed in, flanged or clamped,
depending on the type of diaphragm seal.
• The protective cap of the diaphragm
seal should only be removed just before
mounting in order to protect thediaphragm.
• The membrane of the diaphragm seal of
the Cerabar S must not be pressed in or
cleaned with pointed or hard objects.
• The diaphragm seal and the pressure
sensor together form a closed andcalibrated system which is filled withfilling fluid through a hole in the upper

The Commubox FXA 191 connects intrinsically safe Smart transmitters with a HART or
INTENSOR protocol to the RS 232 C serial interface of a personal computer. This enables
the transmitter to be remotely operated with the Endress+Hauser Commuwin II operating
program. The Commubox FXA 191 is designed for use in intrinsically safe signal circuits.

Cerabar S

On devices without a display, you can set the lower and upper-range values with thereference pressure and an ammeter. The reference pressure should be near the lower
and upper range-values. The associated current value must be calculated using thefollowing equation:
I = 4 mA +16 mA • (p − p URV )(p LRV − p URV )I – Current valuep – Reference pressure is near lower
or upper range-values
pLRV – Pressure lower range-value
pURV – Pressure upper range-value

Example: Set a pressure transmitter asfollows:
Lower range-value: pLRV = 0 bar andUpper range-value: pURV = 1.0.

5 Pressure Measurement

The "Zero Correction" (V9H5) parameter offers a further possibility of carrying out position
calibration. Besides the display value, and in contrast to position calibration using bias
pressure (V0H5/V0H6), the current value is balanced with the on-site display (measured
value (V0H0)).

Zero correction

When carrying out a zero correction, an applied pressure is assigned a correction value
using "Zero Correction" (V9H5). This shifts the sensor characteristics curve according to
the diagram and the "Low Sensor Trim" (V7H4) and "High Sensor Trim" (V7H5) values arerecalculated. The "Zero Correction Value" (V9H6) matrix field indicates the value by which
the sensor characteristic curve was shifted.
The "Zero Correction Value" (V9H6) is calculated as follows:• "Zero Correction Value" (V9H6) ="Sensor Pressure" (V7H8) – "Zero Correction" (V9H5)
The "Sensor Pressure" (V7H8) indicates the effective applied pressure.

If calibration is carried out with water, or if the product changes, the calibration can be
simply corrected by entering a density factor.

Density correction

old density

Example: A vessel is filled with water and then calibrated. The density of water (olddensity) is 1 g/cm3. The vessel will be later used as a storage tank and filled with the new
medium to be measured. The new density is 1.2 g/cm3. V3H4 still contains the factory
setting of 1, i.e. the actual factor is 1.

6.3 Dry calibration
Dry calibration is a theoretical calibration which can be carried out even though the
Cerabar S is not mounted and with a vessel filled to any height. The "empty" calibration
point is usually at the mounting point of the measuring cell. If measurement starts at
another level, then this must be included in the calculation. The requirements for a dry
calibration are:
• The heights of the calibration points "empty" and "full" are known.
• The density factor is known.
• The pressure for "empty" and "full" has been calculated (p = ρgh)

Selecting the operating mode enables two vessel shapes to be chosen• vertical – "level linear" and• horizontal – "level cylindrical horizontal".

7.4 Editing limits
To avoid incorrect device functioning because of excessively large or excessively smallvalues, for some parameters there is a minimum and maximum permissible input value(editing limits). The set measuring range must be within these editing limits. An attempt
to exceed or undershoot these editing limits generates an error message (refer to
Chapter 7.1 Diagnosis of errors and warnings).
The following parameters are checked to make sure they are within the editing limits:• Set 4 mA Value (V0H1)• Set 20 mA Value (V0H2)• Set 4 mA Value Automatically (V0H3)• Set 20 mA Value Automatically (V0H4)• Set Bias Pressure (V0H5)• Bias Pressure Automatically (V0H6)

There are also editing limits for the "Low Sensor Trim" (V7H4), "High Sensor Trim" (V7H5)
and "Zero Correction" (V9H5) parameters. For the parameters, the editing limits aredefined by the sensor limits and the applied pressure.

Editing limits for zerocorrection andrecalibration

To carry out a recalibration or a zero correction, the device must have a reference
pressure (Refer to Chapter 6.1, Section on "Zero Correction" and Chapter 9.5"Recalibration"). Enter a value assigned to the applied pressure using the relevant "Low
Sensor Trim" (V7H4), "High Sensor Trim" (V7H5) or "Zero Correction Value" (V9H5)
parameters.
• Calculation of the value for the lower editing limit of V7H4, V7H5 and V9H5:"Sensor Pressure" (V7H8) – 10% of the sensor end value• Calculation of the value for the upper editing limit of V7H4, V7H5 and V9H5:"Sensor Pressure" (V7H8) + 10% of the sensor end value
The "Sensor Pressure" parameter (V7H8) shows the applied pressure on the device.
#

Example:1

Sensor: 0…10 bar (Sensor end value = 10 bar)
applied pressure = "Sensor Pressure" (V7H8)= 0.1 bar (e. g. depending on position)

2

The applied pressure (V7H8) can be
assigned to a value between the upper andlower editing limits using the "Zero Correction"(V9H5) parameter. In this example values
from –0.9 bar to 1.1 bar.
Value for lower editing limit, V9H5 ="Sensor Pressure" – 10% of sensor end value
0.1 bar – 0.1 • 10 bar = 0.1 bar – 1.0 bar =–0.9 bar
Value for upper editing limit, V9H5 ="Sensor Pressor" + 10% of sensor end value
0.1 bar + 0.1 • 10 bar = 0.1 bar + 1.0 bar =1.1 barEndress+Hauser

8.4 Recalibration
If you want to fit the pressure transmitter with a diaphragm seal you can recalibrate thesensor using the "Low Sensor Trim" (V7H4) and "High Sensor Trim" (V7H5) parameters.
The highest measurement accuracy is obtained when the value for the "Low Sensor Trim"(V7H4) parameter corresponds to the 4 mA calibration value (V0H1/V0H3) and the value
for the "High Sensor Trim" (V7H5) parameter to the 20 mA calibration value (V0H2/V0H4).
There must be a known reference pressure when setting a new lower or upper sensor
characteristic curve value. The more accurate the reference pressure is during
recalibration, the higher the accuracy of the pressure transmitter will be later. A new value
is assigned to the applied pressure using the "Low Sensor Trim" (V7H4) and "High Sensor
Trim" (V7H5) parameters.
