Common infrared thermometer faults and how to fix them
Infrared thermometer common failures and their solutions As we all know, industrial production are inseparable from the precision instruments online thermometer to monitor the temperature of the object, online infrared thermometer has been very mature, very common in factories, online infrared thermometer is usually used in conjunction with the instrumentation, very often in the form of a transmitter, that is, the infrared thermometer output signals are processed through the relevant circuitry, and converted into some standard signal output, such as 0 --- 5V voltage or 4 --- 20mA output. Converted into some standard signal output, such as 0 --- 5V voltage, or 4 --- 20mA output. In supporting the use of some minor failures may occur, here are a few common failure phenomena and their solutions:
1: the measured medium temperature increases or decreases, the online infrared thermometer output does not change, this situation is mostly online infrared thermometer sealing problems, may be online infrared thermometer is not sealed, or in the welding accidentally welded infrared thermometer welded a small hole, this situation generally need to replace the infrared thermometer shell in order to solve the problem.
2: online infrared thermometer output error, this case, the possible reasons are more, if the replacement of the online infrared thermometer in the online infrared thermometer, may be the selection of the new infrared thermometer linear range of change and the original is not consistent, resulting in the sensitivity of the error, usually change the infrared thermometer needs to be recalibrated. Of course, online infrared thermometer output error, it may also be the infrared thermometer is not calibrated at the time of the factory, then re-calibrated on the good.
3: online infrared thermometer output signal is not stable, this reason is the temperature source itself, many temperature source itself is generally not a constant temperature, if there are conditions can be important indoor room temperature conditions to observe, and other instruments to monitor the infrared thermometer output signal is stable. If only the instrument display is not stable, that is, the display instrument is not strong anti-interference capability. Of course, listed here is only part of the reason, are more common. In actual use, but also need to understand is the type of online infrared thermometer and application characteristics and other information, to be able to better use it.
