Description of measument devices
I. Humidity, air temperature and snow temperature
This combined instrument is equally valuable to service personnel and snow machine operators alike. Measurement tolerance is +/- 2% and is equipped with a highly sensitive sensor. A contactless infrared temperature gauge may be supplied, if desired.
II. Snow humidity
The snow humidity measuring instrument determines snow humidity via the capacitve resistance of snow crystals. The ground covered by snow serves as the dielectric.
III. Snow specific weight
A weighing instrument provides she specific weight per m³ directly.
The nozzles, water pressure and injection time are set at the start of slope preparation based on these five measurement results. These measurements are repeated continuously, as the conditions of the slope change from top to bottom during preparation, and the continuous readjustment of the water pressure and injection time guarantees a final constant slope from top to bottom for the racers.
The injection time is set using a special electronic timer.
