Demien,
Firm OMEGA has type OS523 IR Thermometer to measure -28 TO 1370 ° C
We use VANZETTY ( Mass. US ) IR thermometer with a few meters glass fibre
light gide . 5000 $ sensor PbS with electronic shopper 1Hz to
discharge the charge sensitive detector .
For the experimenters :
In anny CD drive you find IR sensors like SELENIDE TELURIDE sensors .
Some LEDs are IR sensor material like InGaAs
Intrusian IR sensor is SILICON FET with a 10 000 nm wavelength Ge filter.
IR night vision converter use CsI kathode and 16 KV to the ZnS anode .
It sees 400-1300 nm from visible glow 500 ° C and up .
( Normal use with invisible lightning 900-1300 nm .)
IR Themperature measurement and vision in fals colous ,good for heat loss
pictures detection cost 5 000 to 10 000 $
For stoves IR is too fansy and expensive !
The good old THERMOCOUPLE Ni/CrNi and Pt/PtRo is less combersome and
spoiling NGO money.
Regards
Frans
