  • Instrument insolator and method of making same
    Patent number: 5154083
    Abstract: A method of making an isolator flow device for use in a process fluid system. The device has a body and an elastomeric sensor ring in the body, through which process fluid flows. There is an annular space outside the sensor ring for communicating outside the body to sense pressure on the ring by the process fluid. In the method, the ring is formed by in-situ molding to the body, and is bonded to the body at its opposite ends, leaving an intermediate portion unbonded. Then, the elastomer will shrink annularly to create an annular space between the body and the ring.
