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.
