Infrared thermometer principle and selection method
Infrared thermometer by the optical system, photoelectric detector, signal and signal processing. Display output and other components. Optical system convergence of its field of view of the target infrared radiation energy, infrared energy focused on the photodetector and transformed into the corresponding electrical signals, the signal is then converted into the temperature value of the target to be measured.
Benefits of using infrared thermometer
Convenience. Infrared thermometers provide rapid temperature measurements, and in the time it takes to read a leaky connection with a thermocouple, an infrared thermometer can read the temperature of virtually any connection. In addition, because the thermometer is solid, lightweight (less than 10 ounces), and easy to carry in a holster when not in use. So you can take them with you when you're doing factory tours and daily inspections.
Accurate! Another advanced feature of infrared thermometers is their accuracy, usually within 1 degree. This capability is especially important when you are doing preventive maintenance, such as monitoring poor production conditions and special events that will cause equipment damage or downtime. Because most equipment and plants run 365 days, downtime equals reduced revenue, and you can prevent such losses by scanning all field electronics-circuit breakers, transformers, fuses, switches, buses, and switchboards-for hot spots. With infrared thermometers, you can quickly detect even small changes in operating temperatures and solve problems before they sprout, reducing the expense and scope of repairs caused by equipment failure.
Safe! Safety is the most important benefit of using an infrared thermometer. Unlike contact thermometers, which can accurately read hard-to-reach or inaccessible targets, infrared thermometers allow you to read the target temperature within the range of the instrument. Non-contact temperature measurements can also be taken in areas that are unsafe or difficult to contact, such as near steam valves or heating ovens, where they don't risk burning your fingers if you don't take care of contact measurements. Measuring supply/return air temperatures up to 25 feet above your head is as easy as taking a measurement at hand, and Raytek infrared thermometers are laser-sighted for easy identification of the target area. Your job just got a whole lot easier with Raytek infrared thermometers.
