FLANGELESS DIFFERENTIAL PRESSURE TRANSMITTER FOR INDUSTRIAL PROCESS CONTROL SYSTEMS

摘要

An industrial pressure transmitter (12), for use in industrial process control systems (10), comprises a differential pressure sensor (56) and an integrated process connector (26) connected to the differential pressure sensor (56). A process fluid flow duct (39) extends through the process connector (26) and receives an industrial process fluid. A primary element (64) is positioned in the process fluid flow duct (39) for producing a pressure differential in the process fluid across the primary element (64). The differential pressure sensor (56) is connected to the process fluid flow duct (39) to sense the pressure differential across the primary element (64).
