Method for measuring the temperature of a metallic cooking vessel

摘要

The method involves recording a resonant circuit parameter at an inductive sensor and determining the temperature of the pot from a characteristic section of the temperature time profile. The absolute value of the measurement value at a defined point of the characteristic section is used as the demand value for heater regulation. The temperature of a ferromagnetic carrier is measured and a resonant circuit parameter correction value is derived. The method involves recording a resonant circuit parameter against time as a measurement value at an inductive sensor (20) and determining the temperature of the pot (21) from a characteristic section of the temperature time profile. The absolute value of the measurement value at a defined point of the characteristic section is used as the demand value for regulating a heater (13). The temperature of a ferromagnetic carrier (15) is measured and a correction value for the resonant circuit parameter is derived. AN Independent claim is also included for the following: (a) an electrical heater with temperature measurement, especially a cooking point on a cooking hob.
