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 →  47 section. 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 →  47 section. The MWP may be applied at the device for an unlimited period. The MWP can also be found on the nameplate.

Measuring principle

Ceramic process isolating diaphragm used in PMC51 (Ceraphire®)

A0020465

1 Air pressure (gauge pressure sensors) 2 Ceramic substrate 3 Electrodes 4 Ceramic process isolating diaphragm

The ceramic sensor is a dry sensor, i.e. the process pressure acts directly on the robust ceramic process isolating diaphragm and deflects it. 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

• Thanks to ultrapure 99.9% ceramic (Ceraphire®, see also "www.endress.com/ceraphire")

• extremely high chemical stability, comparable with Alloy C

• high mechanical stability

• Can be used in absolute vacuum

Metallic process isolating diaphragm used in PMP51 and PMP55

A0016448

1 Silicon measuring element, substrate 2 Wheatstone bridge 3 Channel with fill fluid 4 Metallic process isolating diaphragm

PMP51

The operating pressure deflects the process isolating diaphragm and a fill fluid transfers the pressure to a resistance bridge (semiconductor technology). The pressure-dependent change in the bridge output voltage is measured and evaluated.

Advantages:

• Can be used for process pressure up to 400 bar (6 000 psi)

• High long-term stability

• Guaranteed overload resistance up to 4 times the nominal pressure

• Significantly less thermal effect compared to diaphragm seal systems

FXN 520

Multidrop-Connector FXN520

Cerabar M

PMP55

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 bridge. The pressure-dependent change in the bridge output voltage is measured and evaluated.

Advantages:

• Depending on the version, can be used for process pressure up to 400 bar (6 000 psi) and simultaneous extreme process temperatures

• High long-term stability

• Guaranteed overload resistance up to 4 times the nominal pressure

Level measurement (level, volume and mass)

Electrical differential pressure measurement with gauge pressure sensors

A0023678

h Height (level) p Pressure ρ Density of the medium g Gravitation constant

Your benefits

• Choice of different level measuring modes in the device software

• Volume and mass measurements in any tank shapes by means of a freely programmable characteristic curve

• Choice of diverse level units

• Has a wide range of uses, even in the following cases:

• in the event of foam formation

• in tanks with agitators of screen fittings

• in the event of liquid gases

A0023680

1 Shut-off valves 2 e.g. filter

In the example given, two Cerabar M devices (each with a gauge pressure sensor) are interconnected. The pressure difference can thus be measured using two independent Cerabar M devices.

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. 23 ms to 35 ms (depending on Min. Slave Interval)

• Cyclic: approx. 8 ms to 13 ms (depending on Min. Slave Interval)

FOUNDATION Fieldbus

• Acyclic: typically 70 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 of +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

• Material of the process isolating diaphragm: 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

Temperature effect [E2]

E2M - Main temperature error

The output changes due to the effect of the ambient temperature [IEC 62828-1 / IEC 61298-3] with respect to the reference temperature [IEC 62828-1 / DIN 16086]. The values specify the maximum error due to min./max. ambient or process temperature conditions.

Total error

The total error of the measuring device comprises the total performance and the influence of longterm stability and is calculated using the following formula:

Total error = total performance + long-term stability

Calculation of the total error with the Endress+Hauser Applicator

Detailed measured errors, such as for other temperature ranges, for example, can be calculated with the Applicator "Sizing Pressure Performance".

Calculation of the diaphragm seal error with the Endress+Hauser Applicator

Diaphragm seal errors are not taken into consideration. Diaphragm seal errors are calculated separately in the Applicator "Sizing Diaphragm Seal".
