Tips: What are the types of displacement sensors?

Displacement sensors are a category of sensors used to detect and measure changes in an object's position. Based on their operating principles and measurement methods, they can be broadly classified into contact and non-contact types. Contact displacement sensors detect displacement by directly contacting the measured object. Typical examples include potentiometer-type sensors and draw-wire sensors. They feature simple structures and low costs, but long-term use may lead to wear and reduced accuracy. Non-contact displacement sensors detect displacement through electromagnetic, optical, capacitive, or Hall effect methods, such as LVDT, capacitive, laser, and magnetic induction sensors. These enable high-precision, high-response-speed measurements resistant to environmental interference. Based on output signal type, they can be further categorized into analog and digital outputs. By measurement direction, they are classified as linear displacement and angular displacement sensors, meeting diverse application requirements. Modern displacement sensors undergo continuous optimization in precision, stability, and durability, enabling their widespread adoption across mechanical manufacturing, automation control, aerospace, and scientific research experiments.
