Installation Of Thermocouple

In production, due to the different measured object, conditions, and measurement requirements, the installation methods of thermocouple are also different. Besides much consideration, there are three main aspects of thermocouple installation:  temperature measuring accuracy, safety, and convenient repair.


In order to avoid the temperature measuring element is damaged, you should ensure that it has sufficient mechanical strength. For the protection of the temperature sensing element, there should be protected screen or protection tube, then, the installation method of the temperature measuring element should depend on the specific circumstances. You should ensure the sealing of thermocouple. Working under high temperature thermocouple should be installed vertically, in order to prevent the deformation at high temperature. If it must be installed horizontally, the length of it should not be too long. Furthermore, there should be the protection of thermocouples. If the temperature measuring element is mounted in the pipeline with high flow velocity, it should be obliquely installed in the pipeline bend. When the medium pressure exceeds 10MPa, there must be protection coat on the measuring element. Moreover, when install the thermocouple, you should also consider whether it is convenient to change and repair.
