A sensor
By combining induction coil and Hall elements in the sensor, using magnet units to move in the through hole, the problem that existing sensors cannot feedback the valve core movement status in real time is solved, and the precise measurement of the valve core position and speed is achieved. It is suitable for Precision control system, and has the advantages of compact structure and impact resistance.

Abstract
The present invention relates to a sensor for simultaneously detecting the speed and displacement of an object to be measured, the sensor comprising a main body, a through hole being provided thereon, the through hole being arranged along the axial direction of the main body; an induction unit comprising an induction coil and at least one pair of Hall elements, the induction coil being wound around the main body, and the induction coil being coaxially arranged with the through hole; a magnet unit comprising a connecting piece and a magnetic piece, the magnetic piece being assembled on the connecting piece, the connecting piece being configured to be connected to the object to be measured, and when the object to be measured moves, the magnetic piece is driven to move in the through hole; a control unit comprising an acquisition control board. The present invention can simultaneously measure the displacement and speed of the object to be measured, thereby clearly reflecting the movement state of the object to be measured, so as to facilitate accurate control of the object to be measured; and the sensor has a compact structure, is easy to be integrated into different systems or equipment, and has the advantages of shock resistance and high temperature resistance.
