Thermocouple head

Points for attention in Shanghai thermocouple welding

by:JVTIA     2022-04-05
Made of sheathed thermal resistance, thermal resistance lead, and then through the stainless steel protection tube, after several times of drawing and annealing, the sheathed thermal resistance lead (equivalent to the sheathed thermocouple material) is formed. Next, the material of the thermal resistance and temperature sensitive components is reduced to the required length, the lead tabs are stripped, and the thermal resistance leads are butt welded. The quality of the welding seam determines the measurement effect of the thermal resistance of the sheath. The following issues should be paid attention to in the welding project of the armored thermocouple: the lead wires of the thermal resistance pass through the magnesium oxide insulating shell respectively. It was then passed through a stainless steel tube filled with magnesia. Or use an existing prefabricated sheath. You need to buy a head, the inner diameter is a bit larger than the outer diameter of the stainless steel tube, as long as it can be covered. Note: The sealing length should not be less than the thermocouple shielding length. What should be paid attention to when welding electric sheath resistance temperature measuring resistance? According to online reports, in recent years, more and more manufacturers have taken the sheathed thermal resistance as the core of the assembled thermoelectric resistance, and have transformed the traditional assembled thermal resistance. With the development of technology and the improvement of people's concept of use, the thermal resistance of components has been completely replaced by the thermal resistance of the sheath that is constantly updated. Armored thermocouple is a new type of thermoelectric resistance developed with reference to the manufacturing process of armored thermocouple. The product has fast thermal response, bending resistance, high pressure resistance, shock resistance, and durability. Like the assembled thermoelectric resistance, as a temperature measurement sensor, there are usually recording devices, displays, recording devices and adjustment devices, and it can also be used as the temperature sensing element of the assembled thermoelectric resistance.
