ABSTRACT:
A redundant pressure transmitter for redundantly measuring pressure of a process fluid comprises a transmitter housing, transmitter circuitry, a remote seal assembly including a first pressure sensor, and a second pressure sensor positioned in the transmitter housing. The remote seal assembly also comprises a remote seal flange, a communication system and a capillary tube. The remote seal flange communicates with the process fluid and the first pressure sensor senses the process fluid pressure at the remote seal flange. The communication system relays output of the first pressure sensor to the transmitter circuitry, and the capillary tube communicates the process fluid pressure to the transmitter housing via a fill fluid, where the second pressure sensor senses the pressure of the process fluid through the fill fluid.
