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. Pay attention to the pressure/
temperature dependency. The OPL may only be applied for a short 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. Pay attention to the pressure/temperature
dependency. The MWP may be applied at the device for an unlimited period. The MWP can be found
on the nameplate.
3 The maximum sensor measuring range corresponds to the span between the LRL and URL. This
sensor measuring range is equivalent to the maximum calibratable/adjustable span.
4 The calibrated/adjusted span corresponds to the span between the LRV and URV. Factory setting: 0 to

5 Installation
5.1 Installation conditions
5.1.1 General instructions
• Do not clean or touch process membrane with hard and/or pointed objects
• Do not remove process membrane protection until shortly before installation
Always firmly tighten the housing cover and the cable entries.
1. Counter-tighten the cable entries.
2. Tighten the coupling nut.
5.1.2 Installation instructions
• A position-dependent zero point shift (when the vessel is empty the measured value does
not display zero) can be corrected
• To ensure optimum readability of the onsite display, rotate the housing and onsite display
• Endress+Hauser offers a mounting bracket for installing the measuring device on pipes or
walls
• Use flushing rings for flanges if there is a risk of medium buildup or clogging at the process
connection
• The flushing ring is clamped between the process connection and process
• Material buildup in front of the process membrane is flushed away and the pressure
chamber is vented via the two lateral flushing holes
• When measuring in media containing solids (e.g. dirty liquids), installing separators and
drain valves is useful for capturing and removing sediment
• Using a valve manifold allows for easy commissioning, installation and maintenance
without interrupting the process
• When mounting the device, establishing the electrical connection and during operation:
prevent the penetration of moisture into the housing
• Point the cable and connector downwards as much as possible to prevent the penetration of
moisture (e.g. rain water or condensation)

Installation Cerabar PMC71B HART
14 Endress+Hauser
5.1.3 Installation instructions for thread
• Measuring device with G 1 ½" thread:
Place the flat seal on the sealing surface of the process connection
Avoid additional tension on the process membrane: do not seal the thread with hemp or
similar materials
• Measuring device with NPT thread:
• Wrap Teflon tape around the thread to seal it
• Only tighten the measuring device at the hex bolt; do not turn it by the housing
• When screwing in, do not overtighten the thread; tighten the NPT thread to the required
depth according to the standard
• For the following process connections a tightening torque of max. 40 Nm (29.50 lbf ft) is
specified:
• Thread ISO228 G ½" with flush mount process membrane
• Thread DIN13 M20 x 1.5 with flush mount process membrane
• NPT 3/4" with flush mount process membrane
Mounting sensor modules with PVDF thread
LWARNING
Risk of damage to process connection!
Risk of injury!
‣Sensor modules with PVDF thread must be installed with the mounting bracket provided!
‣PVDF is only intended for metal-free applications!
LWARNING
Material fatigue from pressure and temperature!
Risk of injury due to bursting of parts! The thread can become lose if exposed to high pressure
and temperature loads.
‣The leak-tight integrity of the thread must be checked regularly. Use Teflon tape to seal
the ½" NPT thread.
5.1.4 Orientation
NOTICE
Damage to the measuring device!
If a heated measuring device is cooled during the cleaning process (e.g. by cold water), a
vacuum develops for a short time. As a result of this, moisture can enter the sensor via the
pressure compensation element (1).
‣Mount the measuring device with the pressure compensation element (1) pointing
downwards or to the side.

A0038723
• Keep the pressure compensation element (1) free from contamination
• The measuring devices are mounted according to the same guidelines as manometers
(DIN EN 837‑2)
• Use shutoff devices and siphons
• The orientation depends on the measuring application
5.2 Mounting the measuring device
5.2.1 Pressure measurement in gases
Mount the measuring device with the shutoff device above the tapping point so that any
condensate can flow into the process.
5.2.2 Pressure measurement in vapors
A siphon reduces the temperature to almost the ambient temperature. The defined water
column only causes minimal (negligible) measured errors. Only minimal (negligible) thermal
effects on the device.
Observe the maximum permitted ambient temperature of the transmitter!
• Ideally, mount the measuring device with the O-shaped siphon below the tapping point
The device may also be mounted above the tapping point
• Fill the siphon with liquid before commissioning
5.2.3 Pressure measurement in liquids
A siphon reduces the temperature to almost the ambient temperature. The defined water
column only causes minimal (negligible) measured errors. Only minimal (negligible) thermal
effects on the device.
Observe the maximum permitted ambient temperature of the transmitter!
• Mount the measuring device with the shutoff device below or at the same level as the
tapping point.
• Fill the siphon with liquid before commissioning

Installation Cerabar PMC71B HART
16 Endress+Hauser
5.2.4 Level measurement
• Always mount the measuring device below the lowest measuring point
• Do not install the measuring device at the following positions:
• In the filling curtain
• In the tank outlet
• In the suction area of a pump
• At a point in the tank which could be affected by pressure pulses from the agitator
• Mount the measuring device downstream from a shutoff device: the calibration and
function check can be carried out more easily
5.2.5 Seal for flange mounting
NOTICE
Seal pressing against the process isolating diaphragm!
Incorrect measurement results!
‣Ensure that the seal is not touching the process isolating diaphragm.
