Abstract
A pressure sensor module and method for pre-installation without a converter module. The pressure sensor module is hermetically sealed and can remain undamaged in an installation environment without a converter module. The pressure sensor module can be assembled later with a converter module in the installation environment. The pressure sensor module includes an isolator, a pressure sensor and a circuit that provides a bus for energization, control and a digital pressure output. The bus is connected to contacts in an insulating feedthrough. An integrally formed hermetic external support structure surrounds the pressure sensor and circuit. The hermetic external support structure has a threaded process fluid inlet around the isolator, and a threaded support sleeve supporting the feedthrough.
