Abstract:
A pressure sensor module, comprising:a transducer having an isolator within a threaded process fluid inlet, and having a pressure sensor coupled to the isolator; the isolator including an isolator diaphragm having a peripheral edge; a circuit coupled to the pressure sensor and providing a bus for energization, control, and a digital representation of pressure; a feedthrough comprising a module connector having contacts coupled to the bus, the contacts including contact portions exposed for electrical connection in the process environment and having an insulator surrounding the contacts; and a housing that is welded to the peripheral edge of the isolator diaphragm, sealed to the feedthrough, and that is integrally formed and surrounds the pressure sensor and the circuit, the housing protecting the transducer, and the circuit from inadvertent opening in the process environment, the housing including the threaded process fluid inlet, and a threaded sleeve supporting the feedthrough, the sleeve forming a module support.
