Description:

Compact, reliable and cost-efficient. The SHM 30 snow depth sensor reliably determines snow depths up to 10 meter within seconds and with Millimeter precision. Based on an opto-electronic distance sensor emitting visible eye-safe laser light, the SHM 30 allows probing distances up to 30 meter to detect the surface level. Unlike snow depth sensors using ultrasonic methods, the laser distance measuring technique is Independent of temperature changes. Even if the measuring process is impaired by precipitation, the SHM 30 reliably finds the snow surface due to its mode of operation. Further evaluation of the transmitted signal strength allows discrimination between snow and grass.
 

Supplementary description:

A compact laser sensor with RS232, 10m cable
 

Special features:

  • Determination of snow depth over long distances using opto-electronic measuring technique
  • MTBF (meantime between failure) >40.000h (duty cycle 30% 3 measurements/min)
  • The build in heater does mainly keep the build in laser diode in specs to ensure a long lifetime
  • Very compact and weatherproof housing
  • Efficient background light suppression
  • Allows discrimination between snow and grass
