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.
