How to judge of the electric heating pipe temperature by single head heating tube color
Surface power an important detail parameters of the electric heating tube is a single head electric heat pipe. Resistivity is too large, access to certain current, surface power is big; the resistivity is too small, access to certain current, surface power is small. So little power electronics, will choose small diameter small current, but the size of the current depends on the size of the resistance, single head electric heat pipe in the greater current single head heating tube, the higher the temperature. On the contrary, the electric current in the tube is small, the lower the temperature of the electric heating tube. The length and diameter of single headelectric heating tube is calculated by this.
The test surface temperature of the heating tube to see electric wire color, with the increase of temperature from dark red to red, from close to yellow to white, reached the dazzling blue and white. Based on this fact, we can determine the color of objects from the light temperature.Single head heating tube of high temperature (1100 DEG C), yellow red. The electric heating pipe high temperature (1300 DEG C), yellowish white. To achieve the dazzling blue and white(1500 DEG C) or above. So the test surface temperature of the heating tube is actually watchingthe changes of color.
