Apparatus and Method for Calibration of Sensing Transducers
Abstract
Reciprocity calibration of electromechanical transducers is carried out with three transducers, which are secured to a mass mounted for oscillation as a pendulum. A first transducer is driven and the electrical output of a second transducer is measured. A third transducer, which must be a linear, reciprocal device, is driven and the electrical output of the second transducer is measured. The first transducer is driven while the electrical output of the third transducer is measured. The sensitivities of the transducers can be deduced from the electrical inputs and the measured electrical outputs by taking advantage of reciprocity. The transducers may be mounted to the pendulum mass two at a time, or alternatively, all three transducers may be fixed to the pendulum mass.
