INFRARED SENSOR SIR TO MEASURE THE SNOW SURFACE TEMPERATURE
The compact infrared sensor SIR provides for 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)
TECHNICAL DETAILS
GENERAL
- Power supply 8 … 36 VDC
- Power consumption max. 100 mA (active measurement)
- Miscellaneous including radiation protection and bracket
OUTPUTS (ANALOGUE)
- Channel 1 selectable: 0/4 … 20 mA, 0 … 5/10 V, thermocouple (J or K) or alarm output (signal source: object temperature)
- Channel 2 sensor temperature (-20 °C … +180 °C)
- Alarm output 0–10 V signal source switchable to object temperature or electronic box temperature if used as alarm output
- Alarm output open-collector-output (24 V/ 50 mA)
INPUT
- Functional inputs F1 to F3 software programmable for the following functions:
- Functions external emissivity adjustment, ambient temperature compensation, trigger (reset of hold functions)
