The moving sensor on surface acoustic waves (SAW) in which moving are measured on a delay of the signal reflected from the platen, moving along a surface of SAW propagation is developed and made. Such sensor can work in a mode of reflection of an interrogating electromagnetic signal, i.e. to be passive and wireless. The maximum measured moving to such gage equally 14 mm with accuracy ±0,1mm.
