Signal Processing and Environmental Conditions of the Infrared Thermometer
Consideration of environmental conditions for infrared thermometers:
The environmental conditions in which the infrared thermometer is located have a significant impact on the measurement results and should be considered and appropriately addressed, otherwise it may affect the temperature measurement accuracy and even cause damage to the thermometer. When the ambient temperature is too high and there is dust, smoke, and steam present, accessories such as protective covers, water cooling, air cooling systems, and air blowers provided by the manufacturer can be selected. These attachments can effectively address environmental impacts and protect the thermometer, achieving accurate temperature measurement. When determining attachments, standardized services should be requested as much as possible to reduce installation costs. When smoke, dust, or other particles reduce the measurement energy signal, a dual color thermometer is the best choice. Fiber optic dual color thermometers are the best choice for environments with noise, electromagnetic fields, vibrations, or other harsh conditions.
In sealed or hazardous material applications (such as containers or vacuum boxes), thermometers observe through windows. The material must have sufficient strength and be able to pass through the working wavelength range of the thermometer used. It is also necessary to determine whether the operator also needs to observe through the window, so it is necessary to choose a suitable installation position and window material to avoid mutual influence. In low-temperature measurement applications, Ge or Si materials are usually used as windows that are opaque to visible light, and the human eye cannot observe the target through the window. If the operator needs to pass through a window target, optical materials that transmit both infrared radiation and visible light should be used. For example, optical materials that transmit both infrared radiation and visible light, such as ZnSe or BaF2, should be used as window materials.
The infrared thermometer is easy to operate and convenient to use:
Infrared thermometers should be intuitive, easy to operate, and user-friendly. Portable infrared thermometers are small, lightweight, and portable instruments that integrate temperature measurement and display output. They can display temperature and output various temperature information on the display panel, and some can be operated through remote control or computer software programs.
In harsh and complex environmental conditions, a system with separate temperature sensors and displays can be chosen for easy installation and configuration. The signal output form that matches the current control equipment can be selected.
Calibration of infrared radiation thermometer:
Infrared thermometers must be calibrated to accurately display the temperature of the target being measured. If the thermometer used exceeds the temperature measurement tolerance during use, it needs to be returned to the manufacturer or repair center for recalibration.
