ABSTRACT:
The coupling and decoupling of one or more of a plurality of differential transformers comprising a digital position probe assembly develops a phase encoded signal indicative of the position or level of a magnetically permeable element such as liquid metal or a lead screw in a nuclear reactor assembly. The phase encoded signal, which is developed as a Gray code, is processed in a phase decoder and digitally converted into a binary coded decimal to provide a digital representation of the level or position of the magnetically permeable material.
