摘要： A pressure sensor module and method for pre-installation without a converter module. The pressure sensor module is hermetically sealed and can remain undamaged in an installation environment without a converter module. The pressure sensor module can be assembled later with a converter module in the installation environment. The pressure sensor module includes an isolator, a pressure sensor and a circuit that provides a bus for energization, control and a digital pressure output. The bus is connected to contacts in an insulating feedthrough. An integrally formed hermetic external support structure surrounds the pressure sensor and circuit. The hermetic external support structure has a threaded process fluid inlet around the isolator, and a threaded support sleeve supporting the feedthrough.

摘要： 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.
