Abstract
Infrared thermometer consists of optical system, photoelectric detector, signal amplifier and signal processing. Display output and other parts, because it and contact thermometer, wet and dry bulb thermometer compared with the advantages of convenient, safe, so it has been proved to be an effective tool for detection and diagnosis of electronic equipment failure.
Working principle of 1. infrared thermometer
The infrared thermometer is composed of optical system, photoelectric detector, signal amplifier and signal processing display output. The optical system converges the infrared radiation energy of the target in its field of view, and the infrared energy is focused on the photodetector and converted into the corresponding electrical signal, which is converted into the temperature value of the measured target.
Where are the main areas of use of 2. infrared thermometers
Infrared thermometers have proven to be an effective tool for detecting and diagnosing electronic equipment failures. You can save a lot of money. With infrared thermometers, you can continuously diagnose electronic connection problems and detect the functional status of uninterruptible power supply (UPS) by finding hot spots at the output filter connection on the DC battery. You can check the battery components and power distribution board terminals, switch gears or fuse connections to prevent energy consumption. Due to loose connectors and combinations, heat will be generated, infrared thermometers help identify insulation faults in circuit interrupters. Or monitor the electronic compressor; the hot spot of the transformer can be scanned daily to detect cracked windings and terminals.
What are the advantages of 3. infrared thermometer compared with traditional contact thermometer?
Convenient! The infrared thermometer can quickly provide temperature measurement. In the time it takes to read a leak connection point with the thermocouple, the temperature of almost all connection points can be read with the infrared thermometer. In addition, because the infrared thermometer is solid, lightweight (both lighter than 10 ounces), and easy to put in a leather case when not in use. So you can carry it when you are in the factory inspection and daily inspection work.! Another thing about infrared thermometers is that they are usually within 1 degree of accuracy. This performance is especially important when you are doing preventive maintenance, such as monitoring harsh production conditions and special events that will cause equipment damage or downtime. Because most equipment and plants operate for 365 days, downtime is equivalent to reduced revenue. To prevent such losses, scan all field electronic equipment-circuit breakers, transformers, fuses, switches, buses and distribution panels for hot spots. With infrared thermometers, you can even quickly detect small changes in operating temperature, and solve problems when they are in the bud, reducing the cost of equipment failure and the scope of maintenance.
