Temperature Sensor - Non-contact temperature measurement advantages: measurement limit the degree of temperature sensing element is not limited, so there is no restriction on the maximum temperature can be measured in principle. For temperatures above 1800 ℃, the main use of non-contact temperature measurement. With the development of infrared technology filter temperature sensor manufacturers, radiation thermometry gradually extended from the visible to the infrared temperature sensor filter specification, below 700 ℃ until room temperature has been adopted, and high resolution. Error introduced as insulation deterioration insulated thermocouple protection tube and pull the plate resulting excessive dirt or salt slag furnace thermocouple between pole and intramural poor insulation, more severe at high temperatures, it will not only lead to thermoelectric power loss but also the introduction of interference, the error resulting sometimes up on Baidu. Thermal error when high temperatures, such as a layer of ash on the filter temperature sensors offer protection tube, dust attached to the above, the resistance increases, hinder heat conduction, then the temperature is lower than the true value showing the value of the measured temperature. Therefore, we should keep the outside clean thermocouple protection tube to reduce errors.
