In the field of mechanical engineering, what are the sensors for measuring displacement and what are their characteristics?
1, advantages:
(1) contact measurement.
(2) High precision.
(3) Strong anti-interference ability
(4) Low cost.
2. Position sensor is used to measure the position of the robot itself. Position sensors can be divided into two types, linear displacement sensors and angular displacement sensors. Among them, linear displacement sensors commonly use linear displacement locators, which have the characteristics of simple working principle, high measurement accuracy and strong reliability. The angular displacement sensor can choose rotary potentiometer with high reliability and low cost. The angle shifter can also use photoelectric encoder, which has two forms: incremental and absolute. Among them, incremental codewheel has been widely used in robot control system.
