Temperature Measurement Methods in Microwave Heating Technologies

In industrial technology processes associated with heating processed material using microwave radiation, measuring equipment is required to control such material’s temperature. This article discusses temperature measurement methods in technological processes using microwave heating systems and investigates the main possibilities, disadvantages, and restrictions of applied contact and noncontact (optical) measurement methods. Moreover, requirements for temperature measurement systems under exposure to strong electromagnetic fields are reported. The possibilities and advantages of spectral pyrometry are especially noted.
