摘要
本文研究的一种实用的光纤压差传感器,通过共光源双膜片结构保证了稳定性,采用波纹膜片得到较高灵敏度.该传感器已用于充压检漏系统,其灵敏度达到56050mV/MPa.零漂小于0.1mV/h,热灵敏度漂移为0.013%/℃.
In this paper, a practical optical fibre differential-pressure sensor is presented. The stability of the sensor is improved by making use of the co--lightsource and dual diaphragms constructions. High sensitivity is obtained by the application of the-corrugated diaphragms. The sensors have been used in a pressure detection system with the sensitivity of 56050 mV/MPa, zero drift of less than 0.1mV/h and thermal drift of 0.013%/℃.
