Abstract
In a nuclear installation, an instrument includes a sensor module connected to a process flange. The sensor module includes a support conduit with support conduit threads. An electronic circuit is wired to a connector that includes a key that is aligned with field circuit contacts of the connector. A thermal and nuclear radiation shield encloses the electronic circuit and includes a shock protection annulus. The connector is secured inside the shock protection annulus. The thermal and nuclear radiation shield includes shield threads that rotatably engage the support conduit threads to rotate an alignment of the key relative to the process flange.
Claims17
An instrument for connection to a process flange and to a field circuit in a nuclear installation, comprising:
- a sensor module that is connectable to the process flange and that includes a support conduit that has support conduit threads and that carries a sensor output lead;
- an electronic circuit that receives a sensor output from the sensor output lead;
- a connector that is wired to the electronic circuit and having field circuit contacts, the connector including a key that is aligned with the field circuit contacts of the connector;
- a thermal and nuclear radiation shield that encloses the electronic circuit and that is shaped to include a shock protection annulus that protrudes from a main body of the thermal and nuclear radiation shield, the connector being secured inside the shock protection annulus, and the main body being shaped to include shield threads that rotatably engage the support conduit threads to rotate an alignment of the key relative to the process flange.
