resistance heating element

基本解釋

The heating element is screwed up by high resistance alloy wires and installed on the hearth's two sides, the rear wall of the furnace bottom and the furnace door.
加熱元件的由高電阻合金絲繞制成螺旋狀，安置在爐膛二側(cè)，爐底后墻及爐門上。
If the heading element is much damaged or its resistance value increases too much and cannot reach the furnace temperature, it is better to replace the heating elements with mew ones.
若元件損壞較多或阻值增長過大，無法達(dá)到所需爐溫時(shí)最好全部更換新元件。
A heating element is designed using resistance heating silk and printed board, and an instrument of temperature measurement and control is designed using transistor as the temperature sensor.
