Snow level – ULSN

What is and what is used for

The sensor measures the height of the snow by taking a measurement of the distance of the snow from the sensor case and then subtracts the value found from the zero value place at the level of the base on which the snow deposits. The sensor, managed by a microprocessor control unit, supplies a digital signal lasting a time proportionate to the distance measured in output and is immediately interfaceable with the corresponding datalogger input channel. Heating resistors prevent ice from forming on the reference rod and on the sensor case.


The snow gauge sensor engineering to measure the height of the snow blanket was designed for continuous operation outdoors. The target beneath the sensor must be kept free of rocks and various obstacles that might invalidate its measurement.
