Ultra long thermocouple

Ultra long thermocouple：

Ultra long thermocoupleThe processing technology includes the following steps:

1. Strip steel unwinding and straightening, thermocouple grasping and positioning, thermocouple welding and fixing, thermocouple electrical connection wire management, and thermocouple tube forming

2. The oil well specific oil well of the present inventionUltra long thermocoupleThe processing technology involves designing the unwinding and straightening steps of the strip steel, as well as the automatic grabbing and positioning steps of the thermocouple,

3. The steps of thermocouple welding and fixing, electrical connection line management, and combined with the metal tube rolling process, place thermocouples on the upper surface (inner surface) of the strip steel one by one according to the set spacing. Then, the strip steel is rolled and formed into a sealed thermocouple roll tube through the roll tube forming roller group, which can produce thermocouple rolls over 800 meters long suitable for use in oil wells and other industriesUltra long thermocoupleHigh processing efficiency, saving labor costs; Made ofUltra long thermocoupleThe packaging effect is good, and there is no soldering, which can adapt to harsh usage environments and ensure the service life of thermocouples

Armored thermocouple is a key basic material for manufacturing armored thermocouples, which is made by threading the thermocouple wire into a mineral insulation material magnesium oxide sleeve and then putting it together into a metal protective sleeve. It is processed into a flexible and solid combination through multiple compression and diameter reduction annealing processes. They are widely used in various applications

Various industrial, agricultural, and technological sectors that require temperature measurement. Armored thermocouples have the advantages of slender body, fast thermal response, vibration resistance, long service life, and easy bending.

Widely used in industrial sectors and technological fields such as aviation atomic energy, petroleum, chemical, metallurgical, mechanical, and electric power, especially suitable for installation in special temperature measurement scenarios where pipelines are narrow, curved, and require rapid response and miniaturization. Armored thermocouples are usually composed of main components such as armored thermocouple elements and mounting fixtures.
