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

Features

• 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 ... 5V)
