摘要： A pressure monitoring system provides a pressure sensor and a body that has a first coefficient of thermal expansion and includes at least one opening for accessing a process fluid. At least one isolation diaphragm is coupled to the body and positioned in the at least one opening. The at least one isolation diaphragm has a first surface in communication with the process fluid. At least one passageway is located in the body and configured to contain a fill fluid in communication with a second surface of the first isolation diaphragm. The at least one passageway is positioned between the first isolation diaphragm and the pressure sensor. At least one expansion chamber is coupled to the first passageway and includes an insert having a second coefficient of thermal expansion. The first coefficient of thermal expansion of the body is greater than the second coefficient of thermal expansion of the insert.

摘要： A pressure transducer for clean environments is disclosed. The pressure transducer includes a process coupler, a sensor module, a shield and electronics. The process coupler is configured to couple to a source of process media at a process inlet. The sensor module is coupled to the process coupler and has a pressure sensor therein. The pressure sensor has an electrical characteristic that varies in response to pressure within the sensor module. The shield is disposed adjacent to the process coupler and configured to obstruct substantially all lines of sight between the process inlet and the pressure sensor. Electronics within the transducer are coupled to the pressure sensor to measure the electrical characteristic and provide an indication thereof. A method of sensing a pressure in a clean environment is also provided.

摘要： An electrical connector protects a pressure sensor stem that protrudes from a pressure sensor capsule. The electrical connector includes a baseplate with a central hole and a peripheral wall joined to the baseplate and protruding below the baseplate. The peripheral wall slidingly engages the pressure sensor capsule as the pressure sensor stem passes through the central hole to protrude above the baseplate. A protective wall joined to the baseplate protrudes above the pressure sensor stem and protects the pressure sensor stem. A lead frame in the protective wall provides electrical connections to sensor contact pads on the pressure sensor stem.
