The difference between online infrared thermometer and handheld infrared thermometer
Online infrared thermometer is an effective tool for detecting and diagnosing electronic equipment faults. There are various types of fixed infrared thermometers, and different series play an important role in their respective industries. The main performance indicators of a fixed infrared thermometer include spectral response, response time, repeatability, and emissivity. Fixed infrared thermometers are used in glass and ceramic industries, paper and packaging industries, various kiln temperature measurement applications, and chemical industries to measure the temperature of instruments and meters, thereby detecting the operating status of instruments and ensuring their normal operation.
Online infrared thermometers are mostly used for online temperature measurement in industrial production sites, which measure and transmit/display the temperature of a certain link in the production line in real-time in the control room, and even directly participate in closed-loop control. Such thermometers generally require stability and reliability for long-term use. The handheld infrared thermometer is a type of portable infrared thermometer, which is small and easy to carry. The difference between the two types of infrared thermometers lies in their usage environment and temperature measurement accuracy. Handheld infrared thermometers are easy to carry and can be used in indoor and outdoor working environments, and are basically not limited by environmental conditions. However, compared to online infrared thermometers, their temperature measurement accuracy is slightly lower. Online infrared thermometers have larger blocks than handheld ones, which are not easy to move and are limited by the usage site, but their temperature measurement accuracy is high, You can also compare and analyze the measured temperature online, which is not available with handheld devices. Of course, the price of online infrared thermometers is also higher than that of handheld devices. With a portable heat display system, maintenance personnel can identify potential or existing problems. For example, the engine coil winding overheats, the plugged cooling fins on the transformer, poor capacitor contact, and heat accumulation in the cylinder head of the compressor. Any problem occurs with an increase in temperature, or the temperature curve is completely different from the surrounding temperature、
