| Abstract: | This paper presents the design and working principle of reflective and back pressure pneumatic sensor.The meth-ods which can improve the sensitivity and measurement range of pneumatic sensor are obtained by means of theory. The affection factors of measurement precision are discussed, and the corresponding methods are adopted to compensate the errors. The mea-surement range of developed pneumatic sensor is about 55μm, with 0.02μm in resolution and less than 0.25μm in static error.Therefore, pneumatic measurement technology can be used in high accuracy, high resolution and non-contact dimension measure-ment. |
