Abstract: PROBLEM TO BE SOLVED: To provide a platinum resistor thermometer whose electric characteristics are not deteriorated at a high temperature, and its manufacturing method. SOLUTION: A thin film platinum resistor temperature detecting element 14 is coated with a high quality dielectric layer 24 which is covered with a partition layer 26. This partition layer 26 covers the upper part of the dielectric layer 24, and prevents contaminant from diffusion toward the detecting element 14. The partition layer 26 allows diffusion of oxygen, so that the platinum layer is surrounded by an abundant oxygen atmosphere. The high quality dielectric layer 24 is, e.g. a silicon dioxide layer, and the partition layer 26 is composed of titanium dioxide. By this constitution, the temperature detecting element 14 is not contaminated and the temperature coefficient of the resistor is not deteriorated at a high temperature.

The beam has an opposite end (106) that is shaped to provide a stepped corner (107) with a gap (108) opening at the base of the stepped corner (107), where the gap (108) and isolated from the fluid. A sensing film (112) in the channel adjacent the blind end (104) has an electrical parameter that varies with pressure and electrical leads (110) that extend from the channel and out the gap. A seal (115) fills the gap (108) around the leads (110) and the seal (115) fills a portion of the stepped corner (107). The sensor (100) is preferably formed by direct bonding of single crystal alumina layers (114, 116).

Abstract: A pressure transmitter assembly (100) for measuring a process pressure of an industrial process includes a pressure sensor (500) configured to sense the process pressure. A process coupling couples (106) the pressure sensor (500) to the industrial process. In one example configuration, a phase change material (312) carried in the process coupling (106) 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 (122) is coupled to the process coupling (106) and configured to conduct heat away from the coupling (106) in response to an applied electric current.

Abstract: A system (100) for measuring flow of process fluid through process piping (102), includes a flow restriction (108) in the process piping generating a differential pressure between an upstream side of the restriction (108) and a downstream side of the restriction (108). The differential pressure is related to flow of the process fluid. First and second upstream pressure transmitters (104C, 104D) are coupled to the process piping (102) on the upstream side of the flow restriction (108) and measure respective first and second upstream pressures. First and second downstream pressure transmitters (104A, 104B) are coupled to the process piping (102) on the downstream side of the flow restriction (108) and measure respective first and second downstream pressure of the process fluid. Flow rate of the process fluid is calculated based upon at least one upstream pressure and one downstream pressure.
