Title: Regulator for hot plate - conductivity change of glass hot plate is used as sensor to control supply
IPC: H05B3/74
Filed: 1973-11-08
Abstract: A temperature regulator for the hot plates of electric cookers utilises temperature sensing based upon a change of conductivity of the hot plate. In this instance the hot plate may either be of glass or else a foil or laminate may be fused to the glass and perform as a sensor. The distance between the sensor and the heating element is proportional to the local voltage in the heating element. The output of the temperature sensor is coupled directly to either a relay or amplifier. Once the upper limit of the sensor has been reached the relay will switch off power to the heating element until the temperature has fallen below the limit.
