Interpretation Summary: The PMP71-AAA1FB1AAAAA is a non-hazardous area pressure transmitter with basic 4-20 mA analog output, F13 aluminum housing, M20x1.5 electrical connection, standard 316L wetted parts and membrane, and standard reference accuracy. This configuration is ideal for general industrial high-pressure applications up to 700 bar where explosion protection and advanced communications are not required.
For safety-related applications, SIL-certified devices are marked with the SIL logo on the nameplate.-18
Functional Capabilities and Applications
The Cerabar PMP71 is designed for demanding process environments:
Absolute and gauge pressure measurement in gases, steam, or liquids across all areas of process engineering and process measurement technology-8
Level, volume, or mass measurements in liquids using the device‘s level operating mode and freely programmable characteristic curve for different tank shapes-9
High-pressure applications up to 700 bar (10,500 psi)-8
High process temperatures – up to 150°C (302°F) without diaphragm seal; up to 400°C (752°F) with typical diaphragm seals-8
Custody transfer applications – the PMP71 with metallic process diaphragms meets WELMEC, OIML, and EN standards for custody transfer measurement-9
Marine and offshore environments with GL/ABS marine approvals-35
The patented TempC membrane for the diaphragm seal reduces measured errors caused by environmental and process temperature influences to a minimum.-8
