Tips and tricks on measuring temperature accurately with infrared thermometers
Infrared thermometer by the optical system, photoelectric detector, signal amplifier 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 signal, the signal is then converted into the measured temperature value of the target.
The infrared thermometer can quickly provide temperature measurements, in the time it takes to read a leaking connection with a thermocouple, the temperature of almost all connections can be read with an infrared thermometer. In addition because the infrared thermometer is solid. Lightweight. (all lighter than 10 ounces) and easy to carry in a holster when not in use. So you can take them with you when you are doing factory tours and daily inspections.
Another advanced feature of infrared thermometers is their accuracy, which is usually within 1 degree. This is especially important when you're doing preventive maintenance, such as monitoring poor production conditions and special events that will result in 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 an infrared thermometer, you can quickly detect even small changes in operating temperatures, solving problems in their infancy and reducing the expense and scope of repairs caused by equipment failure.
Safety is the most important benefit of using an infrared thermometer. Unlike contact thermometers, which can safely read hard-to-reach or inaccessible target temperatures, infrared thermometers allow you to read target temperatures within the range allowed by the instrument. Non-contact temperature measurements can also be taken in areas that are unsafe or where contact thermometry is more difficult, like near steam valves or heating ovens, and they don't risk burning your fingers if you don't pay attention while risking contact thermometry. Accurate measurement of 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.
Infrared thermometers have proven to be an effective tool for detecting and diagnosing malfunctions in electronic equipment. With an infrared thermometer, you can continuously diagnose electronic connection problems and detect the functional status of an uninterruptible power supply (UPS) by finding hot spots in the output filter connections on DC batteries, you can inspect battery components and power distribution panel terminals, switch gear or fuse connections to prevent energy consumption; since loose connectors and combinations generate heat, an infrared thermometer helps to recognize insulation faults in loop interrupters. Or monitor electronic compressors; daily scanning of transformers for hot spots can detect cracked windings and terminals.
Raytek non-contact thermometers have three temperature measurement techniques: 1, point measurement: to determine the temperature of the entire surface of an object, like an engine or other equipment; 2, temperature difference measurement: to compare the measured temperatures of two independent points, like a connector or circuit breaker; 3, scanning measurement: to detect changes in the target in a wide area or continuous area. Like refrigeration lines or power distribution rooms.
Selection of infrared thermometer main considerations: 1, the temperature range: each model of the thermometer has its own specific temperature measurement range. The temperature range of the selected instrument should be matched with the temperature range of the specific application. 2, the target size: temperature measurement, the target should be larger than the field of view of the pyrometer, otherwise the measurement error. It is recommended that the size of the measured target is more than 50% of the field of view of the pyrometer is good. 3, optical resolution (D:S): that is, the pyrometer probe to the target diameter ratio. If the pyrometer away from the target, and the target is small, you should choose a high-resolution pyrometer.
Accurate temperature measurement techniques; when measuring the surface temperature of luminous objects, such as aluminum and stainless steel, the reflection of the surface will affect the infrared thermometer readings. Before reading the temperature, you can put an adhesive strip on the surface of the metal, and after the temperature is balanced, measure the temperature of the adhesive strip area. For an infrared thermometer to be able to move back and forth from the kitchen to the refrigerated area and still provide accurate temperature measurements, it is important to take measurements after a period of time to equilibrate the temperature in the new environment. It is best to keep the thermometer in a location where it will be used frequently.
Use an infrared thermometer to read the internal temperature of fluid foods, such as soups or sauces, which must be stirred and then the surface temperature can be measured. Keep the pyrometer away from vapors to avoid contaminating the lens and causing incorrect readings.
