Sažetak
This work presents a simple and inexpensive technique for non-contact industrial temperature measurements based on the two-color method. Since non-contact temperature measurements require expensive instruments such as IR cameras or ratio pyrometers, a simple ratio pyrometer consisting of only two BPW34 PIN photodiodes with narrowband filters is introduced. Temperature measurements using this instrument are carried out on a muffle furnace and are verified with thermal imaging camera - FLIR Thermacam S65. Temperatures measured with both instruments are in good accordance. This method using only two photodiodes presents a reliable and cost effective alternative for temperature measurements and flame monitoring where high temperatures are expected and non-contact measurement is required, such as in industrial furnaces, gasifiers or internal combustion engines.
