Abstract
A probe has a housing which includes a moisture sensor for providing a non-linear moisture-related signal and a signal processor for linearizing the moisture-related signal and converting the signal to a digital output signal indicative of a moisture measurement. Temperature and pressure sensors are also included and provide a temperature-related signal and a pressure-related signal in the probe. The signal processor processes the moisture-related signal as a function of one or both of the temperature and pressure-related signals and provides another moisture-related output signal. The signal processor includes a serial data output for transmitting the digital moisture-related signal and digital temperature and pressure-related signals along a signal data transmission line.
