Introduction to the Necessity of Anti-interference for Infrared Thermometer
During the use of infrared thermometers, there will be some interference to varying degrees. The degree of interference varies from application to application. This situation has brought a lot of trouble to the application in various fields. Therefore, the anti-interference measures for infrared thermometers and the solution to the interference problem in the case of serious interference are another key topic besides design and development.
In the face of interference, sometimes people have no way to start, or even think that the cause of the problem is the interference. Therefore, when the infrared thermometer fails in some occasions with strong electromagnetic waves, after excluding the cause of the instrument itself, the first reason to consider is the problem of electromagnetic interference. There was once a case: a steel forging customer reported that one of the 9 thermometers provided by our company was faulty not long after using it. The customer could not analyze the cause, and finally returned the infrared thermometer to the factory for repair. The induced voltage on the iron material of the equipment is also more than 20 volts, and there are high-voltage and high-frequency equipment around. It is estimated that the source of interference is that the thermometer received a huge source of interference from other equipment through the mounting bracket. Other thermometers that did not fail did the same. Everything is working fine so far.
It can be seen from this that external interference has a huge impact on the infrared thermometer, sometimes not only the impact on the data during the use of the instrument, but even serious damage to the instrument.
