    Abstract: A pressure transmitter connectable to a process line provides an output responsive to a pressure in the process line. The transmitter includes a housing having a base with a process end coupled to an interior cavity formed in the housing, a sensor for sensing the pressure and an isolating assembly mounted at the process end of the housing and isolating fluid in the process line from the interior cavity. The isolating assembly includes an isolation diaphragm configured to be fluidically coupled to the process pressure in the process line, and an isolator plug positioned in the process of the housing adapter. The isolator plug having a lower plug portion providing a first end surface adjacent the isolation diaphragm, an upper plug portion providing a second end surface distally spaced from the first end surface and adjacent a sensor cavity in which the sensor is positioned, a connection mechanism connecting the lower and upper plug portions, and a capillary filled with isolation fluid and extending from the first end surface through the lower and upper plug portions to the second end surface thereby coupling the pressure through the isolation diaphragm and the capillary to the sensor cavity and the sensor. The upper plug portion is formed from a first material and the lower plug portion is formed from a second material having higher corrosion resistance than the first material.

    Abstract: A process variable transmitter for use in an industrial process includes a housing having a cavity formed therein. The housing has a barrier which divides the cavity into first and second cavities. Preferably, measurement circuitry in the first cavity is configured to measure a process variable of the industrial process. A terminal block assembly is positioned in the second cavity. The terminal block assembly forms a seal with the housing thereby forming a third cavity between the barrier and a circuit board of the terminal block assembly.
