The difference between thermometer and handheld infrared thermometer
On-line infrared thermometers are effective tools for detecting and diagnosing electronic equipment failures. There are many varieties of fixed infrared thermometers, and different series play an important role in their respective applicable industries. The main performance indicators of fixed infrared thermometers are spectral response, response time, repeatability and emissivity. Fixed infrared thermometers are used in glass and ceramic industries, papermaking and packaging industries, various kiln temperature measurement applications, and chemical industry to measure the temperature of instruments and meters, so as to detect the operating status of instruments and meters and ensure the normal operation of an instrument. run.
Online infrared thermometers are mostly used for on-line temperature measurement at industrial production sites, to measure and transmit/display the temperature of a certain part of the production line in real time in the control room, and even directly participate in closed-loop control. Such a thermometer generally requires long-term stability and reliability. The handheld infrared thermometer is a kind of portable infrared thermometer, which is a small and portable infrared thermometer. The difference between the two infrared thermometers lies in the use environment and temperature measurement accuracy. The handheld infrared thermometer can be used in indoor and outdoor working environments due to its portability, and is basically not limited by the environmental site. However, compared with the online infrared thermometer Thermometer, its temperature measurement accuracy is slightly worse. The online infrared thermometer is larger than the hand-held one, so it is not easy to move. It is limited by the use of the site, but its temperature measurement accuracy is high, and the measured temperature can be compared and analyzed online. , which is not available in handheld infrared thermometers. Of course, the price of online infrared thermometers is also higher than that of handheld infrared thermometers. With a portable thermal display system, maintenance personnel can identify potential or existing problems. Examples: Overheated engine coil windings, plugged cooling fins on transformers, capacitor contacts, heat buildup in compressor cylinder head. Any problems are accompanied by temperature rise, or the temperature curve is completely different from the surrounding temperature
