What is an infrared thermometer

infrared thermometer There are three main types of infrared thermometer: infrared thermal imager, infrared thermal television, and infrared thermometer (point thermometer).

infrared thermal imager uses infrared detector, optical imaging objective lens and optical scanning system (advanced focal plane technology omits optical scanning system) to receive infrared radiation from the target under test the energy distribution pattern is reflected on the photosensitive element of the infrared detector, between the optical system and the infrared detector, there is an optomechanical scanning mechanism (the focal plane thermal imager does not have this mechanism) to scan the infrared thermal image of the measured object and focus it on the unit or the spectroscopic detector. The detector converts the infrared radiation energy into an electrical signal, and displays the infrared thermal image through a TV screen or monitor after amplification, conversion or standard video signal. This kind of thermal image corresponds to the thermal distribution field of the object surface. In essence, it is the thermal image distribution map of the infrared radiation of each part of the measured target object. Compared with the visible light image, the signal is very weak. Therefore, in order to judge the infrared thermal distribution field of the measured target more effectively in the actual operation process, some auxiliary measures are often used to increase the practical functions of the instrument, such as image brightness, contrast control, real standard correction, pseudo-color rendering technology.

infrared thermometer is the principle that objects with temperatures above absolute zero will radiate infrared rays due to their own molecular motion. After the power signal radiated by the object is converted into an electrical signal by the infrared detector, the output signal of the imaging device can completely simulate the spatial distribution of the surface temperature of the scanned object one by one, processed by the electronic system, and transmitted to the display screen to obtain a thermal image corresponding to the thermal distribution of the surface of the object. Using this method, it is possible to achieve long-distance thermal state image imaging and temperature measurement of the target and analyze and judge it.

Infrared temperature measurement technology plays an important role in product quality control and monitoring, equipment online fault diagnosis and safety protection, and energy saving in the production process. In the past 20 years, non-contact infrared blackbody temperature controller has been developed rapidly in technology, with continuous improvement in performance, enhanced functions, increasing variety and expanding scope of application. Compared with contact temperature measurement method, infrared temperature measurement has the advantages of fast response time, non-contact, safe use and long service life. Non-contact infrared thermometer including portable, online and scanning three series, and equipped with a variety of options and computer software, each series and a variety of models and specifications. Among the various models of temperature sensors with different specifications, selecting the appropriate infrared thermometer model is crucial for the user.
