NCP5A5型高可靠性压力传感器的设计

Design of the NCP5A5 High-reliability Pressure Sensor

为解决与某型号机车配套的空压机压力传感器故障率较高的问题,提出了一种新型压力传感器设计思路,采用全密封二次激光焊接及新技术、新工艺,从基本结构、硬件电路等方面大幅度地提高压力传感器的可靠性。实际装车运用考核表明,该新型压力传感器满足使用要求,效果良好。

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