一种转速传感器间隙检测工装
By designing a speed sensor gap detection fixture, the rotation of components inside the gearbox is simulated to detect multiple data such as sensor gap and sensitivity. This solves the problem that existing equipment cannot comprehensively evaluate sensor performance, improves detection accuracy and applicability, and reduces product risk.
