Algorithm for calculating the eutectic point with active devices for detecting the formation of ice

Glaze sensors are intended for diagnosing the state of the surfaces of roads and runways of airports and allow determination of the freezing temperature and the concentration of aqueous solutions in the form of film precipitations deposited on the sensor surface. When antifreeze reagents fall on the snow or ice surface, their particles dissolve with the formation of a brine of varying concentration, which has a freezing temperature below that of water. In this case, a glaze sensor solves a double problem-to forecast the freezing temperature of a mixture and register the pavement pickling. The presented algorithm for calculating the eutectic point and concentration of salts allows evaluation of the above pavement characteristics from the sensor readings. Original Russian Text ? K.F.
