Ceramic probe rod support assembly

摘要

A probe for use with a measurement instrument includes a circuit connected to the probe. The probe comprises a process adaptor for mounting to a process vessel and including a through bore extending from a connector end to a process end. A counterbore at the connector end defines a shoulder. A support assembly is received in the counterbore and rests on the shoulder. The support assembly comprises an annular rod support having a through opening with a tension rod extending through the opening and secured at opposite sides of the annular rod support. A locking nut secures the support assembly in the counterbore to maintain the annular rod support in compression. A probe rod extends from a process end of the tension rod. A seal assembly is operatively secured to the process adaptor at the connector end with the seal pin in electrical contact with a connector end of the tension rod.
