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. |
Dimensions | Stock size of protective tube: outer diameter 3mm to 25mm, maximum length 2500mm, wall thickness by dimension scale of product 0.5mm to 4mm. Stock size of insulation tube: outer diameter 1mm to 8mm, with single orifice, double, four or more orifices in diameter 0.5mm minimal, maximal length 2600mm, all dimensions can be customized according to user demands.
