Choose a thermometer based on environmental and working conditions
Protective accessories: The environmental conditions in which the thermometer is located have a great impact on the measurement results. If not properly resolved, it will affect the temperature measurement accuracy and even cause damage. When the ambient temperature is high and dust, smoke and steam are present, accessories such as protective covers, water cooling, air cooling systems, and air purges provided by the manufacturer can be used. These accessories effectively address environmental influences and protect the thermometer for accurate temperature measurement. When noise, electromagnetic fields, vibration or inaccessible environmental conditions, or other harsh conditions, smoke, dust or other particles reduce the measurement energy signal, it is more appropriate to use a fiber-optic two-color thermometer.
Window materials: In sealed or hazardous material applications (such as containers or vacuum chambers), the thermometer needs to be viewed through a window. The window material must be strong enough and pass the operating wavelength range of the thermometer being used. Also determine whether the operator also needs to observe through the window, so choose an appropriate installation location and window material to avoid mutual influence. In low-temperature measurement applications, Ge or Si materials are usually used as windows, which are opaque to visible light, and the human eye cannot observe the target through the window. If the operator needs to observe the target through the window, optical materials that transmit both infrared radiation and visible light, such as ZnSe or BaF2, should be used as the window material.
When there are flammable Ran gases in the working environment of the thermometer, a safety infrared thermometer can be used for safe measurement and monitoring in a certain concentration of flammable Ran gas environments.
In the case of harsh and complex environmental conditions, a system with separate temperature measuring head and display can be selected to facilitate installation and configuration and to select a signal output form that matches the existing control equipment.
