SAW (Surface Acoustic Wave) - is an acoustic technology, has proved the most suitable for use in touch equipment located in areas with high attendance. Production from glass, with excellent light transmission characteristics. Heavy Duty 4-6 millimeter glass can be used in the most extreme regimes, it is practically not damaged over time and is designed for long life.Piezoelectric transducers for X and Y axes are sending an electrical signal the frequency of five megahertz, and then converts the crystal momentum in the supersonic. The waves are perpendicular to each other and form a network of co-ordinates the entire field panel. When you touch the screen, you absorb part of the wave passing through at the moment of contact. These sensor signals, in this case differ from the reference, which leads to the automatic determination of the place of X and Y. A unique feature is the ability to determine the effect of touch - the coordinate Z. Digitized data are transmitted to the computer. This process takes a few milliseconds. The screen is a glass panel with piezoelectric transducers (PETs) located at the corners. The edges of the panel are reflecting and receiving sensors. Peculiarity of surfactants screen - is his vandal-proof.
