WARNING This symbol alerts you to a dangerous situation. Failure to avoid this situation can result in serious or fatal injury.
Cerabar PMP71B List of abbreviations A0029505 OPL: The OPL (overpressure limit = sensor overload limit) for the 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.
Cerabar PMP71B Function and system design Measuring principle Metal process membrane Standard device (without diaphragm seal) A0043089 Measuring element Channel with fill fluid Metal process membrane Pressure The pressure deflects the metal process membrane of the sensor. A fill fluid transfers the pressure to a Wheatstone bridge (semi-conductor technology).
Cerabar PMP71B deflected. A fill fluid transfers the pressure to the measuring element on which a resistance bridge is located. 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 •...
IT security with HART, Bluetooth Endress+Hauser can only provide a warranty if the device is installed and used as described in the Operating Instructions. The device is equipped with security mechanisms to protect it against any inadvertent changes to the device settings. IT security measures in line with operators' security standards and designed to provide additional protection for the device and device data transfer must be implemented by the operators themselves.

Cerabar PMP71B ≥ 100 (3.94) A0038734 Recommended installation in a vacuum application Installation above the diaphragm seal Height difference Device Bending radius ≥ 100 mm (3.94 in). Ensure strain relief to prevent the capillary from bending. The maximum height difference depends on the density of the diaphragm seal fill fluid and the lowest absolute pressure that can ever occur at the diaphragm seal (empty container).

Atmosphere Operation in very corrosive environment For corrosive environments (e.g. maritime environment / coastal areas), Endress+Hauser recommends the use of a PVC-coated capillary armor or a PTFE capillary armor for capillaries and the stainless steel housing. The transmitter can be additionally protected by a special coating (Technical Special Product (TSP)).
Use either a device with a temperature isolator or with a capillary in applications with very high temperatures. If vibrations additionally occur in the application, Endress+Hauser recommends the use of a device with a capillary. If a device with a temperature isolator or capillary is used, the device must be mounted with a mounting bracket.
Cerabar PMP71B Process Process temperature range Standard device (without diaphragm seal) NOTICE The permitted process temperature depends on the process connection, process seal, ambient temperature and the type of approval. ‣ All the temperature data in this document must be taken into consideration when selecting the device.
