Resistance temperature coefficient of explosion-proof electric heater

Author: Source: Time: 2019-12-05 Category: Industry News
Explosion-proof electric heaters require that the resistance temperature coefficient of the electrothermal alloy material be very low. For components made of high temperature coefficient electrothermal alloy wire, if uneven heat dissipation is caused due to uneven pitch or other reasons, local overheating will occur during heating or at operating temperature, causing component damage. The temperature coefficient of resistance of iron-chromium aluminum alloy is lower, and the temperature coefficient of resistance of Ni80Cr20 is lower, while the temperature coefficient of resistance of Ni35Cr20 alloy is higher, and measures must be taken to make the heat dissipation uniform in each part.
