After having the basic understanding of the thermocouple thermometer, the most need to grasp is the installation of the thermocouple thermometer. Only after the correct installation, can we operate the thermocouple thermometer correctly, then we all know that the thermocouple thermometer What are the issues to be aware of when installing?
Then we next come to understand the problems that may be encountered in the installation of thermocouple thermometers?
The correct installation of thermocouples and RTD sensors is an important factor in ensuring their measurement accuracy and service life.
First, the installation of thermocouples and thermal resistors should be kept as vertical as possible to prevent deformation of the protective sleeves at high temperatures. However, in the case of flow rates, they must be inserted against the flow direction of the measured medium to ensure that the temperature measuring elements are The full contact of the fluid ensures its measurement accuracy.
In addition, thermocouples and thermal resistors should be installed in the protected pipeline to prevent heat loss. Secondly, when the thermocouple and the RTD sensor are installed in the negative pressure pipeline, it must be ensured that the measurement area has a good seal to prevent the external cold air from entering and make the reading low.
When installed outdoors, the junction box cover of the thermocouple and the RTD should be upward, and the inlet should be downward to prevent rain or dust from entering the junction box. Damage to the thermocouple and the wiring in the RTD's junction box will affect its measurement. Accuracy.
Should always check the thermocouple and the resistance thermometer around the wiring situation, especially the thermocouple thermometer due to the high hardness of the compensation wire material, it is very easy to break off from the terminal to cause circuit failure, so to be well connected not to touch the thermometer too much The wiring and always check to get the correct measurement temperature.
The thermocouple thermometer should be placed as close as possible to the temperature control point to be measured. To prevent heat transfer along the thermocouple or prevent the protection tube from affecting the measured temperature, the thermocouple should be immersed in the fluid under test, at a depth of at least 10 times the diameter.
