ABSTRACT:
A force transducer is provided comprising a vibrator having a pair of plate-shaped vibrating pieces parallel with each other, coupling pieces for joining the respective ends of the vibrating pieces, and attachment portions connected to the coupling pieces, exciting means for causing the vibrator to resonate, and sensing means for detecting the vibrations of the vibrator. An input force to be converted is applied in the longitudinal direction of the vibrating pieces. This force transducer is capable of converting an industiral process variable such as force, pressure, difference pressure, weight or level into a proportional frequency signal at a high efficiency.
