transÂ·duÂ·cer. A device that converts energy from one form to another. transducer (tranzdooÂ´sur), n a device that is activated by power from one system and then supplies a different form of power to a second system; used to convert electric energy into mechanical energy in ultrasonic and sonic scalers.
Efficiency is an important consideration in any transducer. Transducer efficiency is defined as the ratio of the power output in the desired form to the total power input. No transducer is 100 percent efficient; some power is always lost in the conversion process. Usually this loss is manifested in the form of heat.
