The correct way to use an infrared thermometer
Thread Content
When using an infrared thermometer to measure the temperature of motor bearings, it was found that the readings vary depending on the distance, or when measuring from different angles at the same distance. Has anyone encountered this issue? What is the correct distance and angle for measurement, and are there any regulations regarding this?
This isn’t very accurate for measuring temperature; it only gives an approximate value.
What is measured in this way is the temperature of the bearing surface, not the actual temperature of the shaft bearing. Different infrared thermometers have different temperature coefficients, which in turn result in varying temperature measurement ranges and distances. Moreover, the temperature in various parts of the Vagie is greatly affected by external factors. The temperatures around the circumference are definitely different. It is recommended to install a thermal resistor or a bimetallic thermometer. Therefore, the choice of measurement method has a significant impact on accuracy.
