Due to the different subjects, the environmental conditions are different, the measurement requirements, and the measurement methods and measures taken are different, and the problems need to be considered, but in principle, the accuracy, safety of the temperature will And the maintenance is convenient for three aspects.
In order to avoid damage to the temperature measurement element, it should ensure that it has sufficient mechanical strength to protect the temperature of the temperature of the temperature and protective tube, to ensure safety, reliable, temperature measurement, and temperature measurement element, the installation method should be regarded as specific conditions ( If the temperature, pressure, temperature measurement element of the medium and its mounting position, form, etc.) are set. The following is only a few cases to attract attention:
Any temperature measurement element to install pressure must ensure its sealing. The thermocouple working at high temperatures, in order to prevent deformation of the protective tube from high temperatures, generally should be installed vertically, and should not be too long if the level is installed, and the thermocouple is protected by the stent. When the temperature sensing element is mounted in a conduit having a large flow rate of the medium, it should be tilted. In order to prevent excessive erosion of the temperature measurement element, it is best to be installed in the curved place of the pipe. When the medium pressure exceeds 10 MPa, it is necessary to protect the jacket on the measuring element. The installation site of the infrared elbow-type thermocouple / thermal resistance should also consider its disassembly, maintenance, and check in the sufficient space and venue with a longer protective tube, and the thermoelectric resistance can be easily disassembled.
