  • Patent number: 11009897
    Abstract: A remote seal system includes a remote diaphragm having a first side configured to be exposed to a process fluid. A conduit is coupled to the remote diaphragm and includes a fill fluid in fluidic communication with a second side of the remote diaphragm. A temperature sensor is thermally coupled to the conduit and configured to sense a temperature of the fill fluid. In one alternative example, a remote sensing assembly includes a flexible elongate conduit having a first end coupled to a remote diaphragm in fluidic communication with a process fluid and a second end extending a length from the first end to a process fluid pressure transmitter. A substantially incompressible fill fluid is disposed within the flexible elongate conduit. The process fluid pressure transmitter is configured to generate an output value indicative of pressure in the process fluid based on a corresponding pressure in the fill fluid.
