Snow temperature sensor SIR

infraredanalogIP65

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) 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)
