Abstract: This paper proposed a new calibration method for capacitance moisture teller, which is called multi-floating calibration. The measuring ranges of the instrument are enlarged and the precision is improved while the new multi-floating calibration is used. A design example of moisture teller based on capacitance sensor is described.

Key words: multi-floating calibration, capacitance sensor, moisture measurement, multi-floating calibration, capacitance sensor
