由郑州机械研究所承担的“水下旋转机械压力测试技、”课题于1992年9月8日在郑州通过鉴定。该课题研制成功微型压力传感器、防护胶及遥测微机数据自动采集处理系统,是一项技术难度较大的研究项目。微型压力传感器受感部直径6mm、厚度2mm,传感器非线性、重复性基本上不大于0.2％F·S,迟滞小于 Zhengzhou Mechanical Research Institute undertakes the “underwater rotary pressure testing technology,” the subject in September 8, 1992 in Zhengzhou passed the appraisal. The successful development of the subject micro-pressure sensors, protective glue and telemetry microcomputer data acquisition and processing system is a technical difficulty of the research project. Miniature pressure sensor affected part diameter 6mm, thickness 2mm, sensor nonlinearity, repeatability is basically not greater than 0.2% F · S, hysteresis less than
