Which sensors can be selected as small displacement sensors and why?

Hall Elements {Linear}, Optical Scale, Rotary Encoders can be used as small displacement sensors.

Canada FISO's fiber optic micro strain and displacement sensors can measure very small changes. It takes the Fabry Perot cavity interference principle, so can do 0.002 mm resolution.

High-precision linear displacement sensors, Heidenhain, Fagor scale can be selected. Can be less than 1 micron position control accuracy, for precision positioning of hydraulic cylinders can choose linear displacement scale, MTS, Balluf Balluff products can be selected. General closed-loop control accuracy can reach 0.01mm.

Main features

The characteristics of the sensor include: miniaturization, digitization, intelligence, multifunctionality, systematization, networking, which not only promotes the transformation of traditional industries and upgrading, but also the possibility of establishing a new type of industry, which will become a new economic growth point in the 21st century. Miniaturization is based on microelectromechanical systems (MEMS) technology, has been successfully applied to silicon devices made into silicon pressure sensors.
