Document Type and Number:
Japanese Patent JPH0441366
Kind Code:
B2
Abstract:
The invention relates to a process for deriving a measuring signal proportional to the temperature rise of a temperature-time characteristic curve in a heating system having a cooker with cooking material on a heating plate, in which the temperature of the cooker is measured by means of a temperature sensor. The system operates accurately, even during brief temperature oscillations, and using relatively great temperature increments for digitalization of the measuring value signal, when the analogous measuring value signal emitted by the temperature measuring sensor is periodically converted into corresponding digital signals, the digital signals are cyclically fed into memory points of a cyclically-operating memory with n memory points, after each cycle of the memory, a temperature average is calculated from the digital signals stored in the first k and the last k memory points of the memory, wherein k is less than n/2, a measuring signal which corresponds to the temperature difference arising during the preceding cycle is generated from both temperature averages; and after every cycle, all memory points of the memory are cleared and subsequently derived digital signals are fed to the memory.
