How to check the heating temperature of the oil drum heater?

Can the heat release temperature of the silicone rubber heating belt of the oil drum heater meet the temperature environment required by the equipment? We just need to do a simple check.

 

1. An important detail parameter of the device is the surface power of the device. If the resistivity is too large, the surface power will be very large after the corresponding current is introduced.

 

2. If the resistivity is too small, the surface power will be too small when the corresponding current is applied.

 

Therefore, small power appliances use small diameters and small currents, but the current depends on the resistance. The higher the current, the higher the temperature. Conversely, the lower the current in the drum heater, the cooler the device will be. Use this method to calculate the length and diameter of the heater.

 

3. Check the surface temperature of the equipment and the color of the silicone rubber heating belt. As the ambient temperature increases, the color changes from dark red to bright red, then from nearly yellow to white, and finally to a dazzling blue-white.
