When using an infrared thermometer, what environmental conditions should be considered?
The environmental conditions in which the 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. When the ambient temperature is high and there is dust, smoke, and steam present, accessories such as protective sleeves, 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 under noise, electromagnetic fields, vibrations, or difficult to access environmental conditions, or other harsh conditions, fiber optic dual color thermometers are the best choice. A colorimetric thermometer is the best choice. When encountering noise, electromagnetic fields, vibrations, and difficult to access environmental conditions, or other harsh conditions, it is advisable to choose a light colorimetric thermometer.
In sealed or hazardous material applications (such as containers or vacuum boxes), the thermometer is observed through a window. 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 needs to observe through the window, so appropriate installation positions and window materials should be selected to avoid mutual interference. In low-temperature measurement applications, Ge or Si materials are usually used as windows, which are opaque to visible light and cannot be observed by the human eye through the window. If the operator needs to pass through the 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.
When there is flammable gas in the working environment of the thermometer, an intrinsically safe infrared thermometer can be selected for safe measurement and monitoring in a certain concentration of flammable gas environment.
In harsh and complex environmental conditions, a system with separate temperature sensors and displays can be chosen for easy installation and configuration. You can choose a signal output form that matches the current control equipment.
