How to properly install armored thermocouples?

Armored Thermocouple body has a metal sheath, can directly measure the temperature of the medium or placed in the protection tube as a temperature measurement core element, with the advantages of bending, high pressure resistance, fast thermal response time and durable, Armored Thermocouple is usually used with display instrument, paperless recorder and regulator. The temperature of liquid, steam and gaseous media and solid surfaces in various production processes is measured from 0 to 1600°C. In this article, we will share 11 typical armored thermocouple installation legends and installation precautions for technical personnel to use for reference when installing armored thermocouples.

Key points: The measuring end of the armored thermocouple should be located in the center of the pipeline and the length of the bending section should be more than 6 times greater than the direct length of the thermocouple.

Key points: When armored thermocouples are installed at an inclined Angle in the pipeline, the measuring end should be located in the center of the pipeline and ensure that the insertion depth of the armored thermocouple should be more than 10 times the diameter of the thermocouple, and the measuring end must face the direction of the flow of the medium.

Key points: When the armored thermocouple measures the internal temperature of the workpiece, the measuring end of the armored thermocouple should be in contact with the surface of the measured object to improve the accuracy and response speed of temperature measurement.

Key points: When selecting the type, the insertion depth of the armored thermocouple should be reasonably selected and the measuring end should be located in the center of the pipeline

Important: When installing armored thermocouples in bent pipes, the measuring end of the armored thermocouple should be in the center of the pipe and facing the direction of the medium flow.

Key points: armored thermocouples need to reasonably select the insertion depth according to the field conditions, and the minimum insertion depth shall not be less than 10 times the diameter of the thermocouple.

Key points: When the armored thermocouple is buried in the workpiece to measure the temperature, it is appropriate to make the length of the measuring end buried in the workpiece not less than 10 times the diameter of the thermocouple.

Key points: When the armored thermocouple measures the surface temperature of the object, it is appropriate to make the measuring end have a length of not less than 10 times the diameter of the object surface, you can also weld the temperature sensing block at the measuring end, so that the temperature sensing block is in close contact with the surface of the object.
