With the reflectivity of cookware, to obtain the emissivity data of different pots, it is same as improving temperature measurement accuracy.
In nature, when the temperature of object is higher than absolute zero, due to the presence of internal warm-up movement, will constantly to
Surrounding radiated electromagnetic wave.The electromagenetic wave radiation generated due to heat, theoretically, the electromagnetic wavelength of object heat radiation can
To include entire wave spectrum, in industrial temperature range (< 2000K), the heat radiation wavelength being of practical significance, be located at 0.8-100 μm it
Between, and most of energy is located in 0.76-20 μm of infrared ray section, it is seen that in light section, the specific gravity of heat radiation energy is little；
Therefore, the physical essence of infra-red radiation is heat radiation, and the temperature of object is higher, and the infrared ray radiated is more, infra-red radiation
Energy it is stronger.Infrared temperature probe is exactly to utilize thermal effect of radiation, causes temperature liter after so that sensitive detection parts is received radiation
Height, and then the material property in sensor dependent on temperature is made to change.According to this special fence-Boltzmann theorem, infrared survey
The radiation energy P (T) that temperature sensor receives is directly proportional to the emissivity ε of pot body.P (T)=ε σ T4, T is the exhausted of testee
To temperature, σ is this special fence-Boltzmann constant；Therefore, to accurately measure the temperature of pot wall, it must be understood that different cookwares
Emissivity.The following factor of emissivity parameter and tested cookware in relation to: cookware material type (stainless steel, aluminium, cast iron, enamel,
Casserole etc.)；The color (black, blue, yellow, stainless steel metal color, aluminum metal color etc.) of cookware；The clean-up performance of cookware.Transmitting
The directly measurement of rate is very difficult.Therefore we can calculate the corresponding transmitting of cookware by measuring the emissivity of cookware
Rate: due to emissivity+refractive index+reflectivity=1 of object, the refractive index of cookware is close to 0, as long as so measuring the anti-of cookware
Rate is penetrated, corresponding emissivity can be calculated.Reflectivity sensor is made of an infrared transmitter and an infrared remote receiver.
When work, the infrared light of assigned frequency (corresponding wavelength 950nm) is issued by infrared transmitter, by infrared after the reflection of pot wall
Receiver measures received infra-red radiation, compared with the infra-red radiation of transmitting, the reflectivity of available pot wall.And then it calculates
To the emissivity of such cookware, to obtain correct temperature data.
