Snow depth finder

1. Snow depth finder product introduction

The Snow depth finder is an automated snow depth measurement device that automatically measures and records snow thickness in real time.Fengtu Company launched Snow Depth Finder, which uses laser snow recognition and measurement technology to overcome the shortcomings of ultrasonic, electromagnetic wave, weight and other types of sensors that cannot identify snow, thereby achieving extremely high detection accuracy. By monitoring the distance to the location, the thickness of the snow is obtained and the snowfall per unit time is analyzed. This equipment can be used as an independent automatic snow depth monitoring and alarm system, or it can be networked to form a diversified network monitoring.

Scope of application: Widely used in weather stations, port and terminal safety monitoring, road traffic safety monitoring, aviation monitoring, building safety monitoring, agricultural production monitoring, hydrology and water conservancy and many other fields.

Measurement principle: The snow depth sensor uses the principle of a phase laser rangefinder to measure the snow depth. The phase laser rangefinder uses the frequency of the radio band to modulate the amplitude of the laser beam and measure the phase delay caused by the modulated light traveling back and forth to the measurement line once. , and then convert the distance represented by this phase delay according to the wavelength of the modulated light. That is, the indirect method is used to measure the time required for light to travel back and forth from the survey line, thereby solving the snow depth.
