Protective Tube for Temperature Thermocouple, Insulation Tube

Application

Protective tube for temperature thermocouple

Mainly used for protection of thermometric elements, to isolate them from outside and reduce or prevent them being corroded, oxidized or damaged during use.

  Insulation tube 

Made out of material with excellent insulativity, mainly used to isolate poles in different phase of thermometric elements, avoiding interference or contact of two poles resulting in short-circuit, making measurement accurate.

Usage

  Protective tube for temperature thermocouple

During use, the thermometric element insulated well put into the protective tube, and then open end and the couple end are sealed with high temperature clay. When in measurement, the sealed end is inserted into the temperature measuring zone, and it is best to prevent shock cooling or heating from damaging protective tube during use.

Insulation tube

It is ok to put two poles of the thermometric elements into different holes at the same direction, and then furnished with protective tube.

Product classification

Alumina ceramic thermocouple protective tube, insulation tube 

Material  

By operating temperature, due to variable alumina, it is further divided into 99.7 (corundum), 99 (corundum), 95 (corundum), 85 (alumina porcelain), 75 (mullite porcelain), chemical porcelain (40 aluminum), for materials above, the more the alumina, the higher the operating temperature, the maximum aluminum content vertical use at 1710°C,the minimum aluminum use at 1100°C. More at Chemical and Physical Index Table.
