Thermocouple head

Through single thermocouple head of color to judge the temperature of thermocouple

by:JVTIA     2020-11-08
Thermocouples are specially converts electrical energy into heat energy electrical components, due to its cheap, easy to use, easy installation, no pollution, is widely used in all kinds of heating, at present there are a lot of manufacturer of electric heating element, thermocouple brand also has a lot of, the service life of the thermocouple is very long, the service life of the general design has more than 5000 hours.


thermocouple and metal tube electric heater elements, is put into the electric heating element in the metal tube, thermocouple and then fill the gap part closely with good heat resistance, thermal conductivity and the crystallization of the insulation of magnesia powder, in the other process. It has simple structure, high mechanical strength, high thermal efficiency, easy installation, long service life, etc. Is widely used in all kinds of saltpeter tank, water tank, oil tank, acid and alkali trough, the fusible metal melting furnace, air heating furnace, drying oven, drying oven, hot pressing molding device, etc.

how to judge by the color of the single head thermocouple temperature thermocouple? At ordinary times is very red metal was burned, you will know, but don't know how many degrees, this is also to experienced people can tell. Thermocouple is the one important detail parameters of single head the surface power of the thermocouple.


the resistivity is too big, after into a certain current surface power is large; On the contrary, the smaller the thermocouple in the current, the lower the temperature of the thermocouple.


single head length and diameter of thermocouple is calculated after such.


with the increase of temperature change from dark to bright red, from close to yellow to white again, achieve dazzling blue and white.
