  • Control Of Resistance Heating (AREA)

Abstract

PURPOSE:To find whether the function of a heating body is right or wrong early and easily by providing an excitation display lamp circuit in series to the heating body so that the applied potential difference is made thoroughly higher than the lighting operation voltage when the resistance value of the heating body is within the preset range and made lower when it exceeds the preset range. CONSTITUTION:An excitation display lamp circuit 3 is provided in series to a heating body 1, the potential difference sufficient to light a display lamp 4 is generated between both ends of the excitation display lamp circuit 3 when the resistance value of the heating body 1 is within the preset range, and this voltage is applied to light the display lamp 4. On the other hand, when the resistance value of the heating body 1 exceeds the preset range, the potential difference between both ends of the excitation display lamp circuit 3 is made lower than the lighting operation voltage of the display lamp 4. The excitation state to the heating body can be thereby found easily and early.
