Abstract
A high strength, high frequency acceleration transducer is used for measuring the acceleration of an impacted machine or structure. The acceleration transducer includes a diaphragm, the diaphragm including one or more strain gages for producing an output signal indicative of the transducer flexure. The diaphragm is securely clamped or held over part of its surface, and is free to deflect over other parts, for example, the remainder of its surface—the diaphragm can be clamped or held along its circumference with its middle free to flex, or alternatively the diaphragm can be clamped or held along its center with the outside portion of the diaphragm free to flex. The diaphragm preferably includes one or more holes positioned relative to the strain gages to concentrate the strains locally within the diaphragm towards the strain gages. Due to the small size, profile, shape, and configuration, the acceleration transducer is able to withstand high impact forces and reliably to measure acceleration without being damaged and while avoiding resonance or the like which would degrade the output signal from the strain gages.
