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 → 52.
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 → 52.
The MWP may be applied at the device for an unlimited period.
The MWP can also be found on the nameplate.

Measuring principle
Devices with ceramic process isolating diaphragm (Ceraphire®)
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)
→ 13)
• 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)

Devices with metallic process isolating diaphragm
1 Silicon measuring element, substrate
2 Wheatstone bridge
3 Channel with fill fluid
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
A0016448
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

The AI Block receives the measuring data from the Sensor Block,
(selectable via a channel number) and makes the data available to
other function blocks at its output. Enhancement: Digital outputs for
process alarms, fail safe mode
This block contains the discrete data of the Diagnose Block (selectable
via a channel number 0 to 16) and provides them for other blocks at
the output.
This block converts the discrete input and thus initiates an action
(selectable via a channel number) in the DP Flow Block or in the
Service Block. Channel 1 resets the counter for max. pressure
transgressions.
can be used universally for closed-loop-control in the field. It enables
cascade mode and feedforward control. Input IN can be indicated on
the display. The selection is performed in the Display Block
(DISPLAY_MAIN_LINE_CONTENT).
This block is designed to permit simple use of popular measurement
math functions. The user does not have to know how to write
equations. The math algorithm is selected by name, chosen by the
user for the function to be performed.
The Input Selector Block facilitates the selection of up to four inputs
and generates an output based on the configured action. This block
normally receives its inputs from AI Blocks. The block enables the
selection of maximum, minimum, average and ‘first good’ values.
Inputs IN1 to IN4 can be shown on the display. The selection is
performed in the Display Block (DISPLAY_MAIN_LINE_CONTENT).
The Signal Characterizer Block has two sections, each with an output
value that is a non-linear function of the input value. The non-linear
function is generated by a single look-up table with 21 arbitrary x-y
pairs.
accumulates the counts from a Pulse Input Block. The block may be
used as a totalizer that counts up until reset or as a batch totalizer
that has a setpoint, where the integrated or accumulated value is
compared to pre-trip and trip settings, generating a binary signal
when the setpoint is reached.
This block contains all process alarm conditions (working like a
comparator) and represents them at the output.

Performance characteristics for measuring devices with ceramic process isolating diaphragm
Response time HART
• Acyclic: min. 330 ms, typically 590 ms (depending on command # and number of preambles)
• Cyclic (burst): min. 160 ms, typically 350 ms (depending on command # and number of
preambles)
PROFIBUS PA
• Acyclic: approx. 60 ms to 70 ms (depending on Min. Slave Interval)
• Cyclic: approx. 10 ms to 13 ms (depending on Min. Slave Interval)
FOUNDATION Fieldbus
• Acyclic: typically 100 ms (for standard bus parameter settings)
• Cyclic: max. 20 ms (for standard bus parameter settings)
Reference operating conditions
Maximum measured error (total performance)
• As per IEC 62828-2 / IEC 60770
• Ambient temperature TA = constant, in the range +21 to +33 °C (+70 to +91 °F)
•
Humidity j = constant, in the range: 5 to 80 % RH ± 5 %
• Ambient pressure pA = constant, in the range: 860 to 1 060 mbar (12.47 to 15.37 psi)
• Position of the measuring cell: horizontal ±1°
• Input of LOW SENSOR TRIM and HIGH SENSOR TRIM for lower range value and upper range value
• Zero based span
• Membrane material PMC71: Al2O3 aluminum oxide ceramic FDA, ultrapure 99.9 %
• Supply voltage: 24 V DC ±3 V DC
• Load with HART: 250 Ω
• Turn down (TD) = URL/|URV - LRV|
The performance characteristics refer to the accuracy of the measuring device. The factors
influencing accuracy can be divided into two groups
• Total performance of measuring device
• Installation factors
All performance characteristics are in conformance with ≥ ± 3 sigma.
The total performance of the measuring device comprises the reference accuracy and the ambient
temperature effect and is calculated using the following formula:
Total performance = ± √ ( (E1)² + (E2)²)
E1 = Reference accuracy
E2 = Temperature effect per ±28 °C (50 °F)
(corresponds to the range from –3 to +53 °C (+27 to +127 °F))
Calculation of E2:
E2 = E2M + E2
E2M = Main temperature error
E2E = Electronics error
The values refer to the calibrated span
