Working Principle of Thermal Radiation Meters
These meters operate based on the Stefan-Boltzmann Law, which states that the total energy radiated per unit surface area of a black body is directly proportional to the fourth power of the black body’s temperature. Mathematically, it’s expressed as E = σT4, where E is the emitted energy, σ is the Stefan-Boltzmann constant (5.67 x 10-8 W/m2K4), and T is the absolute temperature in Kelvin.
By measuring the emitted thermal radiation, these meters infer the temperature of the object under observation. Advanced models incorporate features like infrared sensors and laser targeting to enhance accuracy and ease of use.
