• Sensor: 10 bar (150 psi)					• Calibrated/Adjusted measuring span: 0...5 bar
• Upper range limit (URL) = 10 bar (150 psi)					(0...75 psi)
					• Lower range value (LRV) = 0 bar
Turn down (TD):					• Upper range value (URV) = 5 bar (75 psi)
TD	=		URL
		|URV	-	LRV|

Risk of injury!

Sensor modules with PVDF thread must be installed with the mounting bracket provided!

! WARNING

Material fatigue from pressure and temperature!

Risk of injury if parts burst! The thread can become loose if exposed to high pressure and temperatures.

The integrity of the thread must be checked regularly and the thread may need to be retightened with the maximum tightening torque of 7 Nm (5.16 lbf ft). Teflon tape is recommended for sealing the ½" NPT thread.

4.4Installation instructions

•Due to the orientation of the Cerabar S, there may be a shift in the measured value, i.e. when the container is empty, the measured value does not display zero. You can correct this zero point shift either via the "zero" key on the electronic insert, or on the outside of the device or via the onsite display. See ä 30, "Position of operating elements", ä 31, "Function of operating elements" and ä 65, "Position adjustment".

•For PMP75, please refer to ä 17 "Installation instructions for devices with diaphragm seals – PMP75".

•To ensure optimal readability of the onsite display, it is possible to rotate the housing up to 380°. See also ä 24, "Rotating the housing".

•Endress+Hauser offers a mounting bracket for installing on pipes or walls. See also ä 21, "Wall and pipe mounting (optional)".

4.4.1Installation instructions for devices without diaphragm seals – PMP71, PMC71

NOTICE

Damage to the device!

If a heated Cerabar S is cooled during the cleaning process (e.g. by cold water), a vacuum develops for a short time, whereby moisture can penetrate the sensor through the pressure compensation (1).

14	Endress+Hauser

Cerabar S PMC71, PMP71, PMP75 with PROFIBUS PA	Installation

If this is the case, mount the Cerabar S with the pressure compensation (1) pointing downwards.

•Keep the pressure compensation and GORE-TEX® filter (1) free from contamination and water.

•Cerabar S devices without a diaphragm seal are mounted as per the norms for a manometer (DIN EN 837-2). We recommend the use of shutoff devices and siphons. The orientation depends on the measuring application.

•Do not clean or touch process isolating diaphragm seals with hard or pointed objects. •The device must be installed as follows in order to comply with the cleanability

requirements of the ASME-BPE (Part SD Cleanability):

•Use siphons for pressure measurement in steam. The siphon reduces the temperature to almost ambient temperature. Preferably mount the Cerabar S with the siphon below the tapping point.

Advantages:

–defined water column only causes minimal/negligible measured errors –only minimal/negligible thermal effects on the device

Mounting above the tapping point is also possible. Pay attention to the maximum permitted ambient temperature of the transmitter!

•Fill the siphon with liquid before commissioning.

P01-PMP75xxx-11-xx-xx-xx-000

Fig. 9: Measuring arrangement for level

•Mount Cerabar S below the lowest measuring point. •Do not mount the device at the following positions:

In the fill flow, in the tank outlet or at a point in the container which could be affected by pressure pulses from an agitator.

•Do not mount the device in the suction area of a pump.

•The calibration and functional test can be carried out more easily if you mount the device after a shutoff device.

4.4.2Installation instructions for devices with diaphragm seals – PMP75

•Cerabar S devices with diaphragm seals are screwed in, flanged or clamped, depending on the type of diaphragm seal.

•Please note that the hydrostatic pressure of the liquid columns in the capillaries can cause zero point shift. The zero point shift can be corrected.

•Do not clean or touch the process isolating diaphragm of the diaphragm seal with hard or pointed objects.

•Do not remove process isolating diaphragm protection until shortly before installation.

NOTICE

Improper handling!

Damage to the device!

A diaphragm seal and the pressure transmitter together form a closed, oil-filled calibrated system. The fill fluid hole is sealed and may not be opened.

When using a mounting bracket, sufficient strain relief must be ensured for the capillaries in order to prevent the capillary bending down (bending radius 100 (3.94 in)).

Please observe the application limits of the diaphragm seal filling oil as detailed in the Technical Information for Cerabar S TI00383P, "Planning instructions for diaphragm seal systems" section.

NOTICE

In order to obtain more precise measurement results and to avoid a defect in the device, mount the capillaries as follows:

Vibration-free (in order to avoid additional pressure fluctuations)Not in the vicinity of heating or cooling lines

Insulate if the ambient temperature is below or above the reference temperatureWith a bending radius of 100 mm (3.94 in).

Do not use the capillaries as a carrying aid for the diaphragm seals!

Vacuum application

For applications under vacuum, Endress+Hauser recommends mounting the pressure transmitter below the diaphragm seal. This prevents vacuum loading of the diaphragm seal caused by the presence of fill fluid in the capillary.

When the pressure transmitter is mounted above the diaphragm seal, the maximum height difference H1 in accordance with the illustrations below must not be exceeded.

H1

A0020472

Fig. 10: Installation above the lower diaphragm seal

The maximum height difference depends on the density of the filling oil and the smallest ever pressure that is permitted to occur at the diaphragm seal (empty vessel), see illustration below:

Mounting with temperature isolator

Endress+Hauser recommends the use of temperature isolators in the event of constant extreme medium temperatures which lead to the maximum permissible electronics temperature of +85 °C (+185°F) being exceeded. Depending on the filling oil used, diaphragm seal systems with temperature isolators can be used for maximum temperatures of up to +400 °C (+752 °F). For the temperature application limits, see technical Information, "Diaphragm seal filling oils" section. To minimize the influence of rising heat, Endress+Hauser recommends the device be mounted horizontally or with the housing pointing downwards. The additional installation height also brings about a maximum zero point shift of 21 mbar (0.315 psi) due to the hydrostatic column in the temperature isolator. You can correct this zero point shift at the device.

Information on filling

The diaphragm seal must be filled as soon as it has been welded on.

•After welded into the process connection, the sensor assembly must be properly filled with

a filling oil and sealed gas-tight with a sealing ball and lock screw.

Once the diaphragm seal has been filled, at the zero point the device display should not

exceed 10% of the full scale value of the cell measuring range. The internal pressure of the

diaphragm seal must be corrected accordingly.

•Adjustment / calibration:

–The device is operational once it has been fully assembled.

–Perform a reset. The device must then be calibrated to the process measuring range as

described in the Operating Instructions.
