INSTRUMENT FOR NUCLEAR POWER FACILITY

摘要

In a nuclear installation, an instrument (100) includes a sensor module (110) connected to a process flange (104, 106). The sensor module (110) includes a support conduit (120) with support conduit threads (122). An electronic circuit (126) is wired to a connector (128) that includes a key (133) that is aligned with field circuit contacts of the connector (128). A thermal and nuclear radiation shield (134) encloses the electronic circuit (126) and includes a shock protection annulus (136). The connector (128) is secured inside the shock protection annulus. The thermal and nuclear radiation shield (134) includes shield threads (237) that rotatably engage the support conduit threads (122) to rotate an alignment of the key (133) relative to the process flange.
