Reasons and solutions for high temperature of infrared thermometer
Temperature measurement method of infrared thermometer
1. When using an infrared thermometer to measure the surface temperature of luminescent objects, such as aluminum and stainless steel, the reflection on the surface can affect the reading of the infrared thermometer.
2. Before reading the temperature, a rubber strip can be placed on the metal surface. After the temperature is balanced, the temperature of the rubber strip area can be measured.
3. The use of an infrared thermometer can still provide accurate temperature measurement by walking back and forth from the kitchen to the refrigerated area, which requires a period of time in a new environment to achieve temperature balance before measurement.
4. It is best to place the thermometer in a frequently used location.
Reasons for the High Temperature of Infrared Thermometers
1. The temperature of the measured object was not correctly estimated.
2. The target emissivity is much higher than the expected setting or the emissivity adjustment is incorrect.
3. The size of the measured target spot is too small.
4. There is reflection interference from the background heat source.
5. Incorrect selection and incorrect analysis of the measurement band applicable to the tested target.
6. The electrical noise caused by strong magnetic fields or incorrect selection of interconnecting cables or cables is related to the wiring problem of AC power lines.
7. The thermometer lens or window is turbid.
8. Improper grounding of the cable resulted in no shielding.
The Treatment Method for High Temperature of Infrared Thermometer
When problem one causes it, we can choose other thermometer devices to compare the temperature measurement. If problem two causes it, we can reset the emissivity value. If problem three causes it, we need to adjust the distance of the temperature measurement. If problem four causes it, the solution is to shield it from the influence of the background heat source. If problem five causes it, we need to choose a new one. If problem six causes it, Electromagnetic interference protection is required. If it is problem 7, the solution is to replace the lens or window. If it is caused by problem 8, it can be re wired to solve the problem.
