Common Problems with Infrared Thermometers and How to Fix Them
Infrared thermometer common failures and their solutions Online infrared thermometer has been very mature, very common in factories, online infrared thermometer is usually used in conjunction with the instrumentation, many times in the form of transmitters, that is, the infrared thermometer output signals are processed through the relevant circuitry, converted to 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:
Pyrometer solution one: online infrared thermometer output error, this situation when the possible causes are more, if the replacement of the online infrared thermometer in the online infrared thermometer, may be the choice of a new infrared thermometer linear range of change and the original is not consistent, resulting in sensitivity errors, usually change the infrared thermometer needs to be recalibrated after the infrared thermometer. Of course, online infrared thermometer output error, it may also be infrared thermometer factory not calibrated, then recalibrated on the good.
Pyrometer solution two: the measured medium temperature increases or decreases, online infrared pyrometer output does not change, this situation is mostly online infrared pyrometer sealing problems, may be online infrared pyrometer is not sealed, or in the welding accidentally welded the infrared pyrometer a small hole, this situation generally need to replace the infrared pyrometer shell in order to solve the problem.
Pyrometer solution three: 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 observed in the indoor room temperature important conditions, and other instruments and meters to monitor the infrared pyrometer output signal is stable. If only the instrument display is not stable, that is, the display instrument is not strong anti-interference capability.
But listed here is only part of the reason, are more common. In actual use, you also need to understand is the type of online infrared thermometer and application characteristics and other information, to be able to better utilize it. Jintai science instrument technology Fang Gong to provide you with online infrared thermometer common failures and their solutions hope to help you.
