Abstract

The rim of an electric radiant heater is formed by a multilayer body (13). It can have the cross-sectional shape of a U, whose interior is filled with a good insulating material. In the interior (23) is placed a sensor coil (23) for a pot detection system, where it is well shielded against heat and mechanical influences.
