Determine temperature range with industrial infrared thermometer
Determine the temperature measurement range: the temperature measurement range is one of the most important performance indicators of the pyrometer. Such as infrared era products cover the range of -40 ℃ - +3000 ℃, but this can not be done by a model of infrared thermometer. Each model of pyrometer has its own specific temperature measurement range. Therefore, the user's measured temperature range must be considered accurately and thoroughly, neither too narrow nor too wide. According to the law of blackbody radiation, in the short wavelengths of the spectrum by the temperature-induced changes in radiant energy will be more than by the emissivity error caused by the change in radiant energy, therefore, temperature measurement should try to choose the better short-wave. Generally speaking, the narrower the temperature measurement range, the higher the resolution of the output signal to monitor the temperature, and the accuracy and reliability are easy to solve. Temperature measurement range is too wide, it will reduce the accuracy of temperature measurement. For example, if the measured target temperature is 1000 degrees Celsius, first determine whether the online or portable, if portable. There are many models that meet this temperature.
Narrative of the response time of infrared thermometers
Response time indicates that the infrared thermometer on the measured temperature changes in response speed, defined as the final reading to reach 95% of the energy required by the time, it is with the photodetector, signal processing circuits and display system time constants. New infrared thermometer response time of up to 1ms. which is much faster than the contact temperature measurement method. If the target's movement speed is very fast or measure the target of rapid heating, to choose a fast response infrared thermometer, otherwise it does not achieve a sufficient signal response, will reduce the measurement accuracy. However, not all applications require fast response infrared thermometer. For the stationary or target thermal process when there is thermal inertia, the response time of the pyrometer can relax the requirements. Therefore, the choice of infrared thermometer response time and the target to be measured to adapt to the situation.
