What can be measured through rotary encoder? What is theory?

The most typical is capable of detecting the position of a photoelectric encoder detection mode, the encoded form to change the location to digitize, to obtain the corresponding relationship between the position of digital encoding parameters to achieve the purpose of detecting position. In the photoelectric encoder of the coding section, according to certain rules coded disc is divided into "light and dark" coding stripes, collected by the respective encoded digital photocell array This completes the test. By this principle, it is possible on the measuring position is, the measured angle variation, in combination with other means, can detect many non-power parameters, if combined with the pressure means, can measure barometric pressure, combined with the thermal expansion mechanism, temperature can be measured, combined level mechanism , can measure the depth of the liquid, combined with inertial gyroscope structure, the angular velocity can be measured, and so on.
