Abstract

Due to high-precision, self-cleaning, anti-interference, non-contact and the other advantages, pneumatic measuring has been widely used in the high-precision, non-contact measurement. Traditional back-pressure measurement had been used in ever cases, but with small measuring range (200μm), its application is limited. While reflection-type pneumatic sensor can be used for online, non-contact measurement, and with large measuring rang (4~5mm) and high-precision (5~10μm), it may also be applied to the sensor calibration. But structural design of its measuring head has a huge impact on the range and accuracy of the sensor. In this paper, the operation principle of a new large range non-contact dimension measuring device is introduce, based on hydrodynamics, a finite element model of the measuring head is systematically constructed, by using finite element simulation software, the influence of sensitivity and linear rang from multiple structural parameters and flow parameters would be analyzed. Through simulation results under different parameters, we obtained optimal geometrical parameters of reflection-type pneumatic head, so as to achieve the purpose of optimizing the design of reflection-type pneumatic head. From the simulation results, the characteristic curve after optimization has good linearity and large measurement range.
