Emissivity: Definition and Influence in Non-contact Temperature Measurement

In non-contact temperature measurement, a pyrometer detects the thermal energy or infrared radiation emitted by an object. From this detected radiation, the pyrometer calculates the temperature according to Planck’s radiation law. The amount of energy emitted by the object largely depends on the emissivity of the ...

Optical factors which influence non-contact temperature measurement

Non-contact temperature measurement is based on an optical measuring technique. The extent to which the measurement result is influenced by pyrometer characteristics is often underestimated. When considering the measurement uncertainty of various instruments, one often merely compares this parameter as specified in the ...

Metrological Errors in Non-contact

Practitioners of metrology are often skeptical of non- contact temperature measurement methods, also known as pyrometry. The technical data provided by pyrometer manufac-turers, however, document that these instruments do indeed provide very accurate and precise temperature readings. Aside from the importance of ...
