Measurement of moving by means of an adjustable delay line on surface acoustic waves  // Caspian journal : management and high technologies. — 2010. — №3. — pp. 18-26.

The device for measurement of moving by means of an adjustable line of delay on the surface acoustic (SAW). Measurement of moving is developed and carried out because the delay of the signal reflected from the platen moving along the surface of SAW propagation is developed and made. Such device can work in a mode of reflection of an interrogating electromagnetic signal, i.e. it can be passive and wireless. The maximum measured moving to such gage equally 14 mm with accuracy ±0,1 mm.
