In the production due to the different objects under test, different environmental conditions, different measurement requirements, and thermal resistance installation methods and measures taken are also different, need to consider more problems, but in principle can be considered from the accuracy of temperature measurement, safety, maintenance convenience of three aspects. In order to avoid damage to the temperature measuring elements, it should be ensured that it has sufficient mechanical strength, in order to protect the temperature sensitive elements from wear should be added to the protective screen or protective pipe, in order to ensure safety and reliability, the installation method of temperature measuring elements should be subject
Here are just a few examples to draw attention to: All temperature measuring elements subjected to pressure must be installed to ensure their sealing. Thermocouple working at high temperature, in order to prevent the protective tube from deformation at high temperature, should generally be installed vertically, if it must be installed horizontally, it should not be too long, and use the bracket to protect the thermocouple. If the temperature measuring element is installed in a pipe with a large media flow rate, it should be tilted and installed. In order to prevent the temperature measuring element from being too large erosion, it is best to install in the bend of the pipe. When the media pressure exceeds 10MPa, a protective coat must be added to the measuring element. The installation site of thermocouple/thermistor should also consider its disassembly, repair, calibration of sufficient space and site, with a longer protection tube thermocouple, thermal resistance should be able to easily disassemble.
