There are many pyrometers, which can be basically divided into two categories: contact and non contact pyrometer. Today, let's learn about their advantages and disadvantages.

non contact pyrometer

Generally speaking, contact pyrometers are relatively simple, reliable, and have high measurement accuracy; but because the temperature measurement element and the measured medium need to be fully thermally exchanged, and it takes a certain time to reach thermal equilibrium, there is a delay in temperature measurement. Phenomenon, while being limited by high temperature resistant materials, it cannot be used for very high temperature measurement.

For non-contact pyrometer temperature measurement, for example, infrared thermometers use the principle of thermal radiation to measure temperature. The temperature measuring element does not need to be in contact with the measured medium. The infrared thermometer has a wide temperature range and is not limited by the upper limit of temperature measurement. Infrared thermometers will not destroy the temperature field of the measured object, and the reaction speed is generally relatively fast; but due to the influence of external factors such as the object's emissivity, measurement distance, smoke, dust and moisture, its measurement error is relatively large.

Therefore, the non-contact pyrometer is generally selected for high temperature measurement; in terms of accuracy, the contact type is generally selected.
