How to Determine Emission
1. Use a probe (such as RTD), thermocouple, or other suitable methods to measure the factual temperature of the the object. Adjust the value of emissivity until the temperature reading of the sensor is the same as the factual temperature, that is, the correct emissivity is oked.
2. If part of the surface of the object can be coated, the surface of the object can be blackened with matte carbon black. At this time, the emissivity is about 0}.98. Set the emissivity to 0.98, and measure the temperature of the blackened part. Finally, measure the area adjacent to the blackened part of the object and adjust the emissivity until the heat reading дорівнює фактична температура. це є правильна випромінювальна здатність.
3 оптимізація поверхня температура вимірювання відповідно до наступні критерії:
1. Використання a a вимірювання інструмент to measure the emittivity of an object.
2. Try to avoid reflection; shield the object from the high temperature heat source in the surrounding environment.
3. When the temperature of the object is high, if there are sкілька overlapping wavelengths available, choose a shorter wavelength.
4. For translucent materials, such as glass; when measuring temperature, ensure that the background temperature is uniform and lower than the object temperature.
5. When the emissivity is less than 0.9, the sensor head and the surface of the target object should be kept as vertical as possible. Do not let the кут between the sensor head axis and the surface normal of the object be greater than 45 degree
