专利汇可以提供Radiant surface-heater and temperature sensing assembly专利检索，专利查询，专利分析的服务。并且An assembly comprising a heater for heating a surface by thermal radiation or infrared transfer and a sensor for sensing the temperature of said surface to provide a control signal for adjusting the heat radiated by said heater in accordance with the valve of said signal. An open top container or box-like member of an electrical insulating and low thermal transfer material has secured, to the interior surface of its bottom, an electrical resistance heating element, and the top of the container or member is disposed adjacent the underside of a plate or vitreous material beneath an area of the upper surface of the plate which is to be heated to provide a cooking surface. A divider extends across the interior of the container or box-like member and a temperature sensor having at least one flat side is supported in a channel provided in the upper surface of the divider with the flat side of the sensor in firm physical contact with the underside of the plate in the region of the cooking surface. The sensor is shielded to a substantial degree by the divider but a selected amount of the sensor is left exposed to heat radiated by the heating element to prevent ''''overshoot'''' when the assembly is used in an electrical circuit system for controlling the temperature of the cooking surface.，下面是Radiant surface-heater and temperature sensing assembly专利的具体信息内容。
