Comparison of high-precision infrared thermometer and thermal imaging instrument
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 saving. 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 of high-precision infrared thermometer and infrared thermal imager:
Infrared thermal imager is also infrared thermal imager. Infrared thermal imager is a non-contact temperature measurement device that detects infrared (heat) energy through a detector, and converts it into an electronic signal for processing, and then displays it on the video display. Generate thermal images. The infrared thermometer uses a photodetector, and 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 to convert the detected signal into an electrical signal through the detector.
In terms of use, the infrared thermal imager is used to detect heat, while the infrared thermometer is used to test the temperature. This is the fundamental difference between the two. The infrared camera is a detection device that detects infrared energy (heat) through non-contact and converts it into an electrical signal, and then generates a thermal image and temperature value on the display, and can calculate the temperature value. The infrared thermometer is composed of optical system, photoelectric detector, signal amplifier, signal processing, display output and other parts. The optical system concentrates the infrared radiation energy of the target in its field of view, and its infrared thermal imaging camera focuses on object imaging, such as the infrared thermal imaging camera for military human body imaging. The infrared thermometer focuses on the temperature of the object, looking for hot spots, temperature distribution and so on. Adjust the difference between the upper limit and lower limit of the temperature detection of the instrument to find the object of the desired temperature. There are many general industrial uses.
