Problems solved by technology

However, during the calibration of these four common types of linear displacement sensors, due to the large differences in the structure of different types of sensors, even some calibration devices with a high degree of automation at present, due to the fixed detection platform, will also lead to the installation and fixation of these structures. Different types of linear displacement sensors with large size differences are still not convenient and simple enough
At present, there are mainly the following problems in the process of installing and calibrating fixed line displacement sensors: (1) There are many kinds of line displacement sensors, and there is no universal device to realize the fixed installation and use of most types of line displacement sensors; (2) The efficiency of installation and adjustment is not high. In order to reduce the influence of Abbe error as much as possible and meet the principle of collinearity, it often takes a long time to make repeated adjustments. Even so, it is still impossible to achieve high-precision effects
