Abstract

"Sensor de recipiente en una placa de cocina, con un circuito de medición a baja frecuencia". El circuito (1) sensor detecta en una placa eléctrica de cocina la presencia de un recipiente (2) en cada foco (F1-F4) de caldeo, y comprende un microcontrolador (4) y un generador (6,7) que suministran una corriente (Ig) de alta frecuencia a una respectiva espira sensora (E1-E4) y un campo magnético, y dos señales (Vr0,Vr1) de referencia máxima y mínima para todos los focos (F1-F4) obtenidas en la condición de temperatura de trabajo, y un circuito (9-13) de medición y evaluación del voltaje (Vs) producido en cada espira sensora, y un circuito (11,11'') para la demodulación en baja frecuencia dichas señales (Vs,Vr0,Vr1), y su amplificación diferencial (Vm,Vrr)."Container sensor on a cooktop, with a low frequency measurement circuit". The sensor circuit (1) detects in a kitchen electric plate the presence of a container (2) in each heat source (F1-F4), and comprises a microcontroller (4) and a generator (6,7) that supply a high frequency current (Ig) to a respective sensor loop (E1-E4) and a magnetic field, and two signals (Vr0, Vr1) of maximum and minimum reference for all the foci (F1-F4) obtained in the temperature condition of work, and a circuit (9-13) for measuring and evaluating the voltage (Vs) produced in each sensor loop, and a circuit (11.11 '') for low-frequency demodulation of said signals (Vs, Vr0, Vr1 ), and its differential amplification (Vm, Vrr).
