Multiple frequency grain moisture sensor for combines |
摘要 |
A grain moisture sensing system having an excitation signal source for producing an excitation signal. A sensor cell having a driven plate and a sense plate that applies to the excitation signal for captive measurement between the driven plate and the sense plate to produce a current at the sense plate. Connected to the excitation source is a first synchronous detector and connected to the sense plate is a second synchronous detector.
