Abstract

Un sensor de humedad de grano mejorado para cosechadoras combinadas. Se describe un sensor de humedad de grano que tiene una celda sensora que incluye una placa excitada, una placa sensora próxima y sustancialmente paralela a la placa excitada para efectuar la medición capacitiva a través de un espaciamiento entre la placa excitada y la placa sensora; y una placa de llenado adyacente a la placa sensora y sustancialmente paralela a la placa excitada para detectar si el espaciamiento está lleno con grano. Opcionalmente, la celda sensora incluye una protección próxima y paralela a la placa sensora de modo que la placa sensora esté entre la placa excitada y la protección. El sensor de humedad de grano provee la medición de componentes real e imaginario de una tensión de excitación aplicada a la placa excitada, la medición de componentes real e imaginario de una corriente sensora detectada en la placa sensora, el cálculo de una admitancia compleja de la celda, el cálculo de una admitancia complejo de una admitancia de referencia, y el cálculo de la inductancia específica compleja del grano.
