摘要： A process fluid pressure transmitter has a remote pressure sensor. The transmitter includes an electronics housing and a loop communicator disposed in the electronics housing and being configured to communicate in accordance with a process communication protocol. A controller is disposed within the electronics housing and is coupled to the loop communicator. Sensor measurement circuitry is disposed within the electronics housing and is coupled to the controller. A remote pressure sensor housing is configured to couple directly to a process and is spaced from the electronics housing. A pressure sensor is disposed within the remote pressure sensor housing. The pressure sensor forms at least one electrical component having an electrical characteristic that varies with process fluid pressure. Portions of the electrical component are coupled directly to a multiconductor cable that operably connects the pressure sensor to the sensor measurement circuitry.

摘要： A process fluid pressure transmitter includes a pressure sensor, transmitter electronics, and an isolation system. The pressure sensor has an electrical characteristic that changes with pressure. The transmitter electronics are coupled to the pressure sensor to sense the electrical characteristic and calculate a pressure output. The isolation system includes a base member, and isolation diaphragm, and a fill-fluid. The isolation diaphragm is mounted to the base member and interposed between the pressure sensor and a process fluid. The fill-fluid is disposed between the isolation diaphragm and the pressure sensor. The base member and the isolation diaphragm are constructed from different materials such that the coefficient of thermal expansion of the isolation diaphragm is larger than the coefficient of thermal expansion of the base member.

摘要： Pressure and mechanical sensors include a sensing component formed of a titanium and tantalum alloy having an elastic (Young's) modulus of less than about 80 GPa and a tensile strength of greater than about 1,000 MPa. The high strength and low elastic modulus, together with very low temperature dependence of the elastic modulus and very low linear thermal expansion, result in high resolution and precise measurement over a large temperature range.
