Abstract: A process fluid pressure measurement probe includes a pressure sensor formed of a single-crystal material and mounted to a first metallic process fluid barrier and disposed for direct contact with a process fluid. The pressure sensor has an electrical characteristic that varies with process fluid pressure. A feedthrough is formed of a single-crystal material and has a plurality of conductors extending from a first end to a second end. The feedthrough is mounted to a second metallic process fluid barrier and is spaced from, but electrically coupled to, the pressure sensor. The pressure sensor and the feedthrough are mounted such that the secondary metallic process fluid barrier is isolated from process fluid by the first metallic process fluid barrier.

Abstract: A polymeric remote seal system is provided for coupling a single-use container to a pressure measurement instrument. The polymeric remote seal system includes a process-side coupling, an instrument-side coupling and a fluidic coupling therebetween. The process-side coupling is configured to couple to the single-use container and is formed of a radiation sterilizable polymer. The process-side coupling has a process-side deflectable diaphragm that is configured to deflect in response to pressure within the single-use container. The instrument-side coupling is configured to couple to the pressure measurement instrument and is formed of a radiation sterilizable polymer. The instrument-side coupling is configured to fluidically convey fluid pressure to an isolation diaphragm of the pressure measurement instrument. Tubing fluidically couples the process-side coupling to the instrument-side coupling.

Abstract: A pressure transmitter assembly for measuring a process pressure of an industrial process includes a pressure sensor configured to sense the process pressure. A process coupling couples the pressure sensor to the industrial process. In one example configuration, a phase change material carried in the process coupling is configured to reduce heat transfer from the industrial process to the process variable sensor by changing phase in response to heat from the industrial process. In another example configuration, a thermocouple electric cooling element is coupled to the process coupling and configured to conduct heat away from the coupling in response to an applied electric current.
