The installation of infrared elbow type thermocouple

Time: Views:955

In production due to the different object, the environment condition is different, different measurement requirements, and heat resistance of the installation method and measures is also different, need to consider the question, but can in principle from the accuracy of temperature measurement, safety, convenient maintenance three aspects to consider.


To avoid damage of temperature measuring element, shall ensure that have enough mechanical strength, to protect the heat element is not subject to wear and tear should add protection screen or protection tube, etc., in order to ensure safe and reliable, the installation of the temperature measuring element method should be according to specific situation (such as temperature, pressure, temperature of the medium under test components and the length of the installation location, forms, etc.). Here for only a few cases in order to attract attention:


Every installation of temperature measuring element under pressure, must ensure the sealing. Work under the high temperature of the thermocouple, in order to prevent the protection tube deformation at high temperature, the general should be installed vertically, if must be horizontal installation shoulds not be too long, and protect the thermocouple. If the temperature measuring components installed in the pipeline of medium velocity is bigger, it should be inclined to install. As to prevent the excessive erosion of temperature measuring element, is best installed on the pipe bend. When the medium pressure more than 10 mpa, it must be on the measuring element in protecting coat. Infrared elbow type thermocouple/thermal resistance should also consider the tear open outfit, maintenance, calibration of enough space and space, has a long protection tube of thermocouples, thermal resistance should be able to easily tear open outfit.
