With the hydraulic and pneumatic systems used in the large-stroke high-precision equipment more widely, the requirement of mea-surement accuracy is getting higher and higher for displacement of the output shaft of large-stroke hydro-cylinder/air-cylinder. Displacement sensor is the key for high-precision displacement measurement of large-stroke hydro-cylinder/air-cylinder. But with the stroke of hydro-cyl-inder/air-cylinder more and more large, the requirement of measurement accuracy more and more high, displacement sensors are becoming increasingly difficult to meet the measurement requirements due to subjective and objective reasons .In this paper, firstly, there is a analysis about the characteristics of large-range displacement sensors. Then, this article analyzes the problems the current large-range displacement sensors face to achieve high-precision displacement measurement of large-stroke hydro-cylinder/air-cylinder. Finally, this paper proposes a solution to achieve high precision measurement of large, very large stroke hydro-cylinder/air-cylinder. This solution shows higher measuring accuracy, greater range, stronger adaptation and lower cost. This paper can provide the reference for high-precision displacement measure-ment of hydro-cylinder/air-cylinder.
