Acceleration Strain Transducer with Increased Sensitivity
Abstract
The present invention relates generally to instruments and more particularly to a transducer that can be used with a strain sensor to make an accelerometer. Traditional electrical accelerometers use a magnetic mass supported by a spring in a housing. An induction coil is wound around the interior of the housing. Acceleration is sensed by measuring the electromotive force induced in the induction coil by movement of the magnetic mass. Piezoceramic transducers use a piezoelectric effect to produce a low voltage output in response to force. These sensors usually require a preamplifier to be placed in close proximity. In remote applications, especially those involving arrays of accelerometers, the preamplifiers and telemetry combining signals for transmission to the receive site, can be large and a major factor in the system expense.
