Abstract

The plug has a hollow metal body (1), a current feeder (2) and a tubular metal sheath (3), secured to the body and closed at its tip. Two spirals, one for heating (5) and the other (6) for current control, are embedded in insulating powder (4). The spirals are connected to each other by a spacer element (7,8), having a low thermal conductivity, of length between 8mm and 18mm. The length ratio (Lc/Lr) of the control spiral to the heating spiral is higher than 3.
