Abstract
The position of a control rod located within a nuclear reactor is sensed by a position indicating system utilizing a series of self-exciting reed switch oscillator assemblies mounted along the path of control rod travel. Each reed switch oscillator assembly is preset to provide a constant level output signal when no external flux field is present and to provide an oscillating output signal whenever an external flux field is brought into the vicinity of the reed switch oscillator assembly. The control rod has a magnet mounted thereto which establishes an external flux field and causes the reed switch oscillator assembly proximate to the magnet to provide an oscillating output signal indicative of the position of the control rod.
