Snow Depth Sensor SHM 30
A compact laser sensor for determining snow depths

Compact, reliable and cost-efficient

Benefits

The SHM 30 snow depth sensor reliably determines

• Determination of snow depth over long distances

snow depths up to 10 meter within seconds and

using opto-electronic measuring technique

with millimeter precision.

• Reliable and cost-effective operation

Based on an opto-electronic distance sensor emitting

• Very compact and weatherproof housing

visible eye-safe laser light, the SHM 30 allows probing

• Efficient background light suppression

distances up to 30 meter to detect the surface level.

• Allows discrimination between snow and grass

Unlike snow depth sensors using ultrasonic methods,
the laser distance measuring technique is independent

Applications

of temperature changes.

• Weather service

Even if the measuring process is impaired by precipitation,

•t Traffic and aviation safety, road surveillance

the SHM 30 reliably finds the snow surface due to its

•t Winter sport areas

mode of operation.

•t Water & energy related applications

Further evaluaton of the transmitted signal strength allows
discrimination between snow and grass.
