Protective tube for thermocouple、Insulating tube
use
Protective tube for thermocouple
It is mainly used for the protection of the temperature measuring element, so that the temperature measuring element is isolated from the outside world, reducing or preventing the element from being eroded, oxidized or damaged by external substances in the process of use.
Insulating tube
It is made of good insulating material, which is mainly used to separate the different poles of the temperature measuring element to avoid bipolar interference or contact short circuit, so that the temperature measuring is accurate.
usage
Protective tube for thermocouple
When using, it is to do a good job of insulation and protection of the temperature measuring element set in the protection tube and then the opening end and the couple head with high temperature glue together. When measuring the temperature, insert the sealed end into the temperature measuring area, avoid rapid cooling and rapid heating when using, so as to avoid excessive damage to the protective tube.
Insulating tube
Insert the two poles of the temperature measuring element into different holes in the same direction. After installation, use protective tube set to protect
Detailed product classification
Alumina ceramic thermocouple protection tube, insulation tube
The material
Due to the different use temperature subdivided into different alumina content of 99.7 porcelain (corundum), 99 porcelain (corundum), 95 porcelain (corundum), 85 porcelain (high aluminum porcelain), 75 porcelain (mullite porcelain), chemical porcelain (40 aluminum), the higher the alumina content of the above materials, the higher the use temperature, the higher the vertical use of 1710 degrees Celsius aluminum content, Lower aluminum content is used at 1100 degrees Celsius. Detailed chemical and physical indexes are shown in table.
size
The conventional size of the protective tube is 3mm to 25mm in outer diameter, and the longer length is 2500mm. The wall thickness is 0.5mm to 4mm according to the product size ratio. The conventional size of insulation pipe is 1mm to 8mm in outer diameter. The holes are divided into single hole, double hole, four hole and porous. The diameter is smaller than 0.5mm and the length is longer than 2600mm. Detailed chemical and physical indexes are shown in table.
