A comparison of high precision infrared thermometers and thermal imaging cameras
Infrared temperature measurement technology plays an important role in the production process, product quality control and monitoring, online fault diagnosis and safety protection of equipment, and energy conservation. In the past 20 years, high-precision infrared thermometers have developed rapidly in technology, their performance has been continuously improved, their functions have been continuously enhanced, their varieties have continued to increase, and their scope of application has also continued to expand. Compared with contact temperature measurement methods, infrared temperature measurement has the advantages of fast response time, non-contact, safe use and long service life.
Comparison between high-precision infrared thermometer and infrared thermal imaging camera:
Infrared thermal imaging camera is also an infrared thermal imaging camera. Infrared thermal imaging camera is a non-contact temperature measurement device that detects infrared (heat) energy through a detector, converts it into electronic signals for processing, and then displays them on the video display. Generate thermal images. The infrared thermometer uses a photodetector, which uses infrared energy to focus on the photodetector and convert it into a corresponding electrical signal. The signal is then converted into the temperature value of the measured target. This is the difference between the two temperature measurement principles. The same point is that the detected signal is converted into an electrical signal through the detector.
In terms of purpose, infrared thermal imaging cameras detect heat, while infrared thermometers test temperature. This is the fundamental difference between the two. An infrared thermal imaging camera is a detection device that detects infrared energy (heat) through non-contact, converts it into electrical signals, and then generates thermal images and temperature values on the display, and can calculate the temperature values. The infrared thermometer is composed of an optical system, a photoelectric detector, a signal amplifier and signal processing, and a display output. The optical system gathers the infrared radiation energy of the target within its field of view, and its infrared thermal imaging camera focuses on object imaging, such as military human body imaging infrared thermal imaging cameras. Infrared thermometers focus on object temperature, looking for heating points, temperature distribution, etc. Adjust the difference between the upper and lower temperature detection limits of the instrument to find objects with the desired temperature. It is more commonly used in general industrial applications.
