Title:
PRESSURE TRANSMITTER FOR USE IN INDUSTRIAL PROCESS CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/141655
Kind Code:
A3
Abstract:
A pressure transmitter (10) for measuring a pressure of a process fluid in an industrial process, includes a pressure sensor (16) having an output related to an applied pressure. Measurement circuitry (18,20) coupled to the pressure sensor (16) is configured to provide a transmitter output related to sensed pressure. A pressure coupling face (60) having an opening (48,52) therein is arranged to transfer the applied pressure to the pressure sensor (16). A pressure coupling flange (13) having a flange face (62) abutting the pressure coupling face (60) is configured to convey the process fluid to the opening (48,50) of the pressure coupling face (60). Features are provided to control distribution of a loading force across the pressure coupling face and the flange face.
