The principles and advantages of handheld infrared thermometer guns for industrial households
The infrared thermometer gun is composed of optical system, photoelectric detector, signal amplifier, signal processing, display output and other parts. The optical system gathers the target infrared radiation energy within its field of view, and the size of the field of view is determined by the optical components of the thermometer and its position. When using an infrared radiation thermometer to measure the temperature of an object, the amount of infrared radiation of the object within its band range must first be measured, and then the temperature of the object being measured is calculated by the thermometer.
The single-color thermometer gun is proportional to the amount of radiation within the band, and the two-color thermometer is proportional to the ratio of the amount of radiation in the two bands. The infrared energy is focused on the photodetector and converted into a corresponding electrical signal. The signal passes through the amplifier and signal processing circuit, and is converted into the temperature value of the measured object after correction and ambient temperature compensation according to the built-in algorithm and target emissivity of the instrument.
Advantages of infrared thermometer gun
1. High accuracy. Another advanced feature of infrared thermometer guns is accuracy. Usually the accuracy is within 1 degree. This performance is particularly important when you do preventive maintenance.
2. Easy to use, the infrared thermometer gun can quickly provide temperature measurement. In the time it takes to read a leaking connection point with a thermocouple, the temperature of almost all connection points can be read with an infrared thermometer. In addition, because infrared thermometers are solid and lightweight (all lighter than 10 ounces), they can be easily stored in a leather case when not in use. So you can carry it with you during factory inspections and daily inspections.
3. Good safety. Safety is the most important benefit of using an infrared thermometer gun. Unlike contact thermometers, infrared thermometer guns can safely read inaccessible or inaccessible target temperatures, and you can read the target temperature within the range allowed by the instrument.
