Abstract
The utility model relates to a position sensing device used for a sodium cooled fast reactor fuel handling machine. The output signals of an existing position sensing device for a sodium cooled fast reactor fuel handling machine are unstable; and the actuating signals of a converter in a comparator circuit cannot be adjusted. In the position sensing device used for the sodium cooled fast reactor fuel handling machine, the signal output end of the position sensing device is set as a middle point of a sensor coil; and the middle point of a power transformer is earthed; when the output signals of the position sensing device are converted, the coil signal of the sensing device is amplified firstly, is subsequently rectified and compared. When the position sensing device used for the sodium cooled fast reactor fuel handling machine is employed, the signals outputted by the position sensing device are stable; moreover, as a voltage signal outputted by the coil is greater, a voltage amplitude after rectifying is increased; in this way, the adjusting scope for the actuating signals of the converter is enlarged.
