ABSTRACT:
A method and apparatus for determining the magnitude of a load acting on a stucture by measuring the elapsed time an ultrasonic sound wave requires to travel from a transmitting transducer to a receiving transducer, wherein the elapsed time is then interpolated into an estimate of the load. The elapsed time varies according to the magnitude of the load acting on the structure being analyzed. Depending upon application, the load can be a quantity of force, moment, torque, or pressure. The present invention can also be applied to measuring strain. In various embodiments, the present invention may be used in truck axles to determine load; in pressure vessels to determine pressure or fluid level; in aircraft to determine center of gravity and center of lift; in cranes to determine bending moments and imbalanced loading; or in conveyor belts to estimate belt tension.
