TK7460 Temperature switch, IFM operation mode

IFM temperature switch, IFM operation mode. Diffuse radiation energy is reflected by the hemispherical mirror back onto the surface, forming additional radiation, thereby increasing the effective emission coefficient. In the formula, ε represents the emissivity of the material surface, and p represents the reflectivity of the reflector. As for the radiation measurement of the actual temperature of gases and liquids, the method of inserting a heat-resistant material tube to a certain depth to form a blackbody cavity can be used.
