Abstract: A vibrating strip transducer, wherein a vibrating strip (54) mounted between a fixed mount (52) and a moveable mount (51) and under load (53) directly responds to a change in force applied to the strip with a change in the magnitude of stress in the strip. The change in stress produces a corresponding change in the resonant frequency of vibrating strip (54) which is detected by coil assembly (55) to output a frequency based signal directly related to the force applied. Fluid level and buoyancy sensing embodiments are also disclosed.
