The Sarsys Surface Trailer Friction Tester (STFT) has been a success on the market since it was released in 2003, the same principle as the SVFT and SFT most of the components are the same.

BASIC PRINCIPLE AND GENERAL DESCRIPTION

The measuring system is the famous SARSYS Single Transmission system used in the SARSYS Surface Friction Tester and built into the SAAB 9-5. It is primarily designed for friction measuring on airport runways and taxiways, but can also be used for measuring on roads. The STFT is programmed to measure in accordance with regulations issued by authorities such as ICAO and FAA and designed for both operational and maintenance measuring. The system consists of a measuring wheel which is mechanically geared to the right hand wheel on the trailer. The gear ratio is such that, when travelling along the runway the measuring wheel cannot follow the runway surface freely, but rolls with a certain slip.

MEASURING COMPUTER SYSTEM
