  • Coaxial probe for high temperature and high pressure applications
    Patent number: 6642807
    Abstract: A guided wave radar probe defines a transmission line for use with a measurement instrument including a pulse circuit connected to the probe for generating pulses on the transmission line and receiving reflected pulses on the transmission line. The probe includes a center conductor for conducting the pulses. A conductive outer sleeve is coaxial with the center conductor. The conductive outer sleeve has a process end and a connector end. The process end is exposed, in use, to a process environment being measured. A first cylindrical seal element between the center conductor and the outer sleeve is at the sleeve process end. The first cylindrical seal element is of a first material adapted to withstand a relatively high temperature. A second cylindrical seal element is between the center conductor and the outer sleeve disposed between the first cylindrical seal element and the connector end.
