Title:
改善された温度補償を有する遠隔シールシステム
Document Type and Number:
Japanese Patent JP7354257
Kind Code:
B2
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. A temperature detector is coupled to the flexible elongate conduit and is configured to provide a signal indicative of an average temperature of the fill fluid along the flexible elongate conduit. A compensation system calculates a thermal expansion value based on the average temperature and adjusts the pressure signal based on the thermal expansion value.
