Cloud Height & Snow Depth Sensors

Snow depth sensor

Snow Depth Sensor SHM31

The laser-based snow depth sensor Lufft SHM 31 stands for millimeter-accurate snow level detection over long distances in all weather conditions without any maintenance, due to opto-electronic/laser based rangefinder technology.

Parameters Measured: Snow depth

Measurement Technology: opto-electronic measuring technique (rangefinder; laser distance sensor) with eye-safe laser

Product Highlights: Determination of snow depth over long distances, heating options allow high quality measurements in all weather conditions, simplified installation due to automatic inclination angle compensation

Interfaces: RS485 & RS232 with UMB, UMB-ASCII 2.0 & SDI12 protocol

Compact snow depth sensor

Snow Depth Sensor SHM30

Compact, reliable and cost-efficient. The SHM30 snow depth sensor reliably determines snow depths up to 10 meter within seconds and with Millimeter precision, due to opto-electronic/laser based rangefinder technology.

Parameters Measured: Snow depth

Measurement Technology: opto-electronic measuring technique with eye-safe laser sensor

Product Highlights: Determination of snow depth over long distances, MTBF (meantime between failure) >40.000h, allows discrimination between snow and grass, very compact and weatherproof housing

Interfaces: RS232, RS422, analogue output

Lufft ceilometer
