2. What is a Dual Wavelength Pyrometer?
A dual wavelength pyrometer is an advanced temperature measurement device that utilizes two different wavelengths of light to calculate the temperature of an object. By using two wavelengths, it compensates for the influence of emissivity and allows for more precise and accurate temperature readings. This innovative technology has revolutionized temperature measurement processes by eliminating common errors and limitations associated with traditional single wavelength pyrometers.
3. How Does a Dual Wavelength Pyrometer Work?
The dual wavelength pyrometer operates on the principle of Planck's law of black body radiation. It measures the infrared radiation emitted by an object and calculates its temperature based on the intensity of the radiation at two different wavelengths. By comparing the intensities, the pyrometer compensates for variations in emissivity, which is the measure of an object's ability to emit infrared radiation. This compensation ensures accurate temperature readings even when the emissivity of the object changes.
