Non-contact temperature sensors can be used to measure the temperature of the temperature distribution inside

It can be used to measure the movement of objects, a small thermal capacity, a very rapid temperature change or a small target temperature of the surface of the object, but also can be used to measure the temperature distribution of the temperature inside. Measured object is saying there is no contact between the sensing element, so it also called non-contact Thermometer. Now the most frequently used non-contact thermometer Crank Position Sensors on the basic law of blackbody radiation work, known as the radiation thermometer tables. Radiation thermometry method has the following categories: colorimetric, radiation and brightness of the Act. The above method can only measure the temperature of the corresponding colorimetric, photometric radiation temperature and temperature. However, only about blackbody temperature measurement is the real temperature.
Non-contact temperature sensor Positioning Sensor temperature main advantages: For temperatures above 1800 ℃, generally using a non-contact temperature measurement method; its measurement limit is not affected by temperature sensing element temperature limits the degree of Therefore the highest temperature for the measurement, in principle, is not also limited; infrared technology is now becoming more and more well, and the radiation temperature gradually from the visible to the infrared to expand, until room temperature is lower than 700 ℃ of which can be measured, and and its resolution is very high.
