Difference between online and handheld thermometers
In-line infrared thermometers are effective tools for detecting and diagnosing electronic equipment faults. There are many varieties of fixed infrared thermometers, and different series play an important role in their respective industries. The main performance indicators of fixed infrared thermometer are spectral response, response time, repeatability and emissivity. Fixed infrared thermometer for the glass and ceramic industry, paper and packaging industry, various types of kiln temperature measurement applications and the chemical industry to measure the temperature of instruments and other instruments, so as to detect the operation of the instrumentation to ensure the normal operation of an instrument.
On-line infrared thermometer is mostly used in industrial production site online temperature measurement, the production line of a certain part of the real-time temperature measurement and transmission/display in the control room, and even directly involved in closed-loop control. Such a thermometer, generally require long-term stability and reliability. The handheld infrared thermometer is a portable infrared thermometer, is a small, portable infrared thermometer. The difference between the two types of infrared thermometer in the use of the environment, temperature measurement accuracy is different, handheld infrared thermometer can be used for indoor and outdoor work environment, basically not subject to the limitations of the environment site, but compared to the online infrared thermometer, its temperature measurement accuracy is slightly worse than the online infrared thermometer than the handheld to be a large block, it is not easy to move by the use of the site limitations, but its temperature measurement accuracy is high, but also can be put on the line! Measurement of temperature for comparison, analysis, which is handheld does not have, of course, online infrared thermometer price is higher than the handheld. With the portable heat display system, maintenance personnel can identify potential or existing problems. Examples include overheated engine coil windings, tightly plugged cooling fins on a transformer, poor capacitor contacts, and heat build-up in the cylinder head of a compressor. Any problem that arises is accompanied by an increase in temperature, or a temperature profile that is diametrically opposed to the surrounding temperature.
