To settle the high-fault-ratio problems of air compressor pressure sensor for one locomotive, a novel design was proposedwith a sealed secondary laser welding, new technologies and new processes, which greatly increased the reliability of the pressure sensorfrom basic structure and the hardware circuit. The on-board test showed that the new pressure sensor satisfied the operation requirementwith good effect.
