How to prevent the occurrence of infrared thermometer failure and power failure accidents?
The actual objects that exist in nature are almost not black bodies. In order to clarify and obtain the distribution of infrared radiation, an appropriate model must be selected in theoretical research. This is the quantized oscillator model of body cavity radiation proposed by Planck, which leads to The law of Planck's black body radiation, that is, the black body spectral radiance expressed in wavelength, is the starting point of all infrared thermometer external radiation theories, so it is called the law of black body radiation.
The user's measured temperature range must be considered accurately and comprehensively, neither too narrow nor too wide. According to the law of blackbody radiation, the change of radiation energy caused by temperature in the short-wave band of the spectrum will exceed the change of radiation energy caused by emissivity error. Therefore, it is better to use short-wave as much as possible when measuring temperature.
In the following applications, it can effectively prevent the occurrence of infrared thermometer failures and unplanned power failures.
1. Connector - The electrical connection part will gradually loosen the connector, due to repeated heating (expansion) and cooling (shrinkage) to generate heat, or surface dirt, carbon deposition and corrosion. Non-contact thermometers can quickly identify temperature rises that indicate a serious problem.
2. Motor - In order to maintain the life of the motor, check whether the temperature of the power supply connection line and the circuit breaker (or fuse) are consistent.
3. Infrared thermometer motor bearings - check the hot spots, and regularly repair or replace them before problems occur that cause equipment failure.
