摘要： An improved positional transducer is disclosed which utilizes an elongated, hollow, cylindrical tube of a magnetically saturable material, a sense wire that runs through the tube parallel to its elongated axis and a pair of elongated, generally rectangular shaped magnets of opposite polarity which are closely positioned adjacent diametrically opposite exterior portions of the tube. As the magnets move over in the tube, they provide substantially complete saturation of the tube in the portion over which they extend while the remaining portion of the tube remains unsaturated thereby giving a linear indication of the position of the magnets with respect to the tube. In the improved version, shown herein, adjustments of the electrical slope (volts/inches of travel) are achieved by a slot cut through the wall of the tube in the direction of the tube's length.
