The longest sensor in the world was born

The longest sensor in the world was born in Kunshan, with a total length of 120 meters. This relatively high-precision linear displacement sensor is called an ultra-long magnetic ruler and is now being debugged.

In some large-scale devices, sensors are often installed to improve the accuracy of measurement processing. The birth of these large-scale devices often involves the problem of “backlash” due to distance. For example, if the machining head of the machine tool has a maximum processing length of 15 meters, it must be folded back after reaching this distance, resulting in a "backlash." The ultra-long sensor can achieve absolute position feedback to solve the above problem.

In the fast mechanical movements, precise displacement control is a great challenge, especially the displacement measurement in closed-loop control. This is also the necessity for the development of an ultra-long sensor, which can measure linear displacement and positioning signals at different distances, such as 25 meters, 50 meters, and 100 meters. Its measurement accuracy can reach 0.1 micron, which can greatly meet the current industrial demand.

This sensor solves the problem of closed-loop control displacement measurement in rapid mechanical motion through linear displacement and positioning signals of different distances, which can help the work machine to quickly displace and position quickly, and improve the work accuracy.
