SNOW SURFACE TEMPERATURE SENSOR SIR

SNOW SURFACE TEMPERATURE SENSOR SIR

INFRARED SENSOR SIR TO MEASURE THE SNOW SURFACE TEMPERATURE

The compact infrared sensor SIR provides the exact and non-contact measurement of the temperature of the snow surface.

FEATURES AND ADVANTAGES

  • Highly sensitive infrared temperature sensor for the measurement of the snow’s surface temperature
  • Non-contact measurements, reliable and continuous data, optimum integration into existing systems
  • Robust stainless steel sensor casing with separate zinc die-cast casing for the evaluation electronics (protection IP 65)
  • Tried and tested for operation under harsh climatic conditions
  • Non-contact temperature measurement
  • Easy integration also into existing systems (signal 4 … 20 mA or 0 … 5 V)
