1. A force transducer for converting an applied input force to be measured into an oscillation frequency comprising:

  • a vibrator having a pair of vibrating pieces disposed parallel to each other and symmetrical with respect to the center axis thereof, coupling pieces for joining the respective ends of said vibrating pieces, and attachment portions connected to said coupling pieces;

    exciting means secured to one of said vibrating pieces for causing said vibrator to resonate;

    vibration sensing means secured to the other of said vibrating pieces for detecting the vibration of said vibrator;

    an amplifier coupled between said exciting means and said vibrating sensing means which along with said vibrator form an oscillator, an input force to be converted being applied to said vibrating pieces in the longitudinal direction thereof via said attachment portion, said input force varying the frequency of oscillation of said oscillator whereby said input force may be measured by measuring the frequency of oscillation of said oscillator.
