Online infrared thermometer common faults and their solutions As we all know, industrial production can not be separated from the precision instrument online thermometer to monitor the temperature of objects, online infrared thermometer is very mature, the factory is very common, online Infrared thermometers are often used in conjunction with instruments. Many times they take the form of transmitters. In other words, the signals output by infrared thermometers are processed by related circuits and converted into standard signal outputs, such as 0---5V. Voltage, or 4--20mA output. There may be some minor faults in the matching use. Here are some common fault phenomena and their solutions: 43 Television,Hd Smart Television,Led Television,Liquid Crystal Tv Jiangsu Hengye Precision Technology Co.,Ltd , https://www.hengyejmtv.com
1: When the temperature of the medium to be measured increases or decreases, the output of the online infrared thermometer does not change. This is mostly a problem with the on-line infrared thermometer seal. It may be that the on-line infrared thermometer is not sealed, or It is during welding that the infrared thermometer is accidentally soldered with a small hole. In this case, it is usually necessary to replace the shell of the infrared thermometer.
2: Online infrared thermometer output error is large, in this case, the possible causes are more, if it is to replace the online infrared thermometer in the infrared thermometer, may be the choice of the new infrared measurement The linear range of the thermometer is inconsistent with the original one, resulting in a sensitivity error. Usually the infrared thermometer needs to be recalibrated after it is changed. Of course, online infrared thermometer output error is large, it may be that the infrared thermometer is not calibrated when shipped from the factory.
3: Online infrared thermometer output signal instability, this reason is the source of the temperature itself, many of the temperature source itself is generally not a constant temperature, if conditions can be observed under normal indoor temperature conditions, and other Instrumentation monitors whether the infrared thermometer output signal is stable. If only the instrument display is unstable, it is the display instrument's anti-interference ability is not strong. Of course, only some of the reasons listed here are common. In actual use, it is also necessary to understand the type of on-line infrared thermometer and its application characteristics in order to better utilize it.
