Tips for Measuring Temperature with an Infrared Thermometer
In the production process, infrared temperature measurement technology plays an important role in product quality control and monitoring, equipment online fault diagnosis and safety protection, and energy saving. So, what aspects should be paid attention to when choosing an infrared thermometer?
1. Temperature range:
The temperature range of Raytek products is -50~3000 degrees (section), and each type of thermometer has its specific temperature range. The temperature range of the selected instrument should match the temperature range of the specific application.
2. Target size:
When measuring temperature, the measured object should be larger than the field of view of the thermometer, otherwise there will be errors in the measurement. It is recommended that the size of the target to be measured exceeds 50 of the field of view of the thermometer as well.
3. Optical resolution (D:S):
That is, the ratio of the probe of the thermometer to the diameter of the target. If the thermometer is far away from the target and the target is small, a high-resolution thermometer should be selected.
Tips for measuring temperature with an infrared thermometer:
1. When measuring the surface temperature of luminous objects, such as aluminum and stainless steel, the reflection of the surface will affect the reading of the infrared thermometer. Before reading the temperature, put a rubber strip on the surface of the metal, and measure the temperature of the strip area after the temperature is balanced.
2. If the infrared thermometer can walk back and forth from the kitchen to the refrigerated area and still provide accurate temperature measurement, it must be measured after a period of time in the new environment to reach the temperature balance. The thermometer can be placed in frequently used places.
3. Use an infrared thermometer to read the internal temperature of fluid food, like soup or sauce, must be stirred, and then the surface temperature can be measured. Keep the thermometer away from steam, which can contaminate the lens and cause inaccurate readings.
How Infrared Thermometers Work
Infrared temperature measurement technology is an intuitive, accurate, high-sensitivity, fast, safe, non-contact measurement technology for measuring the temperature field distribution on the surface of an object with a wide range of applications. Any object above absolute zero is constantly emitting thermal radiation due to the movement of its own molecules. The infrared thermometer receives the infrared rays emitted by the object, and then the infrared detector converts the power signal radiated by the object into an electrical signal. After being processed by the electronic system, a thermal image corresponding to the thermal distribution of the surface of the object is obtained, thereby giving the temperature distribution of the surface of the object.
