Sommer - Model SND - Snow Drift Sensor - Brochure

Extremely robust sensor to determine snow drift intensity. The sensing part of the instrument is a cylindrical, anti-abrasion, anti-adhesion and anti-rime coated tube supported by two strong stainless steel arms. The impact of drifting snow and the friction of laminar wind induce a change in internal acoustic pressure. The excitation by snow and wind is discriminated by a specific acoustic, mechanical and electronic design.
