Common fixed infrared thermometer faults and solutions
Common faults and solutions of fixed infrared thermometers. Online infrared thermometers are very mature and common in factories. Online infrared thermometers are usually used in conjunction with instruments, often in the form of transmitters. In other words, the signals output by infrared thermometers are processed by relevant circuits and converted into standard signal outputs, such as 0-5V voltage or 4-20mA output. There may be some minor malfunctions during the use of the equipment. Here are several common fault phenomena and their solutions:
Solution 1: The online infrared thermometer has a large output error. In this case, there are many possible reasons. If the online infrared thermometer is replaced, it may be because the linear change range of the new infrared thermometer is inconsistent with the original one, resulting in sensitivity errors. Usually, after changing the infrared thermometer, it needs to be recalibrated. Of course, the online infrared thermometer has a large output error, and it is also possible that the infrared thermometer was not calibrated properly when it left the factory. In this case, recalibration is sufficient.
Solution 2 of the thermometer: When the temperature of the measured medium rises or decreases, the output of the online infrared thermometer does not change. This situation is mostly due to the sealing problem of the online infrared thermometer. It may be that the online infrared thermometer is not sealed properly, or a small hole was accidentally welded during welding. This situation usually requires replacing the outer shell of the infrared thermometer to solve.
Solution three of the thermometer: The output signal of the online infrared thermometer is unstable, which is caused by the temperature source itself. Many temperature sources themselves generally do not have a constant temperature. If possible, it can be observed under important indoor temperature conditions and other instruments can be used to monitor whether the output signal of the infrared thermometer is stable. If only the instrument display is unstable, it means that the anti-interference ability of the display instrument is not strong.
However, the reasons listed here are only part of the common ones. In practical use, it is also necessary to understand the types and application characteristics of online infrared thermometers in order to better utilize them. Jintai Keyi Technology provides common faults and solutions for online infrared thermometers, hoping to help everyone.
