  • High accuracy level transducer
    Patent number: 9163976
    Abstract: A level transducer has a power supply module, a tuning fork module, a sensing-phase corrector and a controller. The tuning fork module has a tuning fork, at least one piezoelectric driving element, and at least one piezoelectric sensing element. The at least one piezoelectric driving element and the at least one piezoelectric sensing element are stacked on each other, and are mounted on the tuning fork. The power supply module is electrically connected and outputs a voltage to the at least one piezoelectric driving element to deform the at least one piezoelectric driving element. The at least one piezoelectric sensing element is extruded and outputs a voltage signal. The sensing-phase corrector obtains the voltage signal and outputs a clock signal to feedback control the voltage on the at least one piezoelectric driving element to optimize a deformation frequency of each piezoelectric element.
