Patent Searching and Data


Title:
共振圧電センサの共振周波数を決定する方法および装置
Document Type and Number:
Japanese Patent JP2006520899
Kind Code:
A
Abstract:
A method and a device are disclosed to determine the value of the resonant frequency of a resonant sensor subject to an acoustomechanical and/or dielectric load. The sensor is simultaneously and constantly excited at two different frequencies, the first of which is the series resonant frequency, while the second is introduced to detect and compensate the sensor parallel capacitance in an automatic and continuous way.
