Transducer, английский
- A device that converts energy from one form to another, such as optical energy to electrical energy.
- Преобразователь, датчик, при?мник
- A device which converts power in one kind of system to power in another form, e.g., a loudspeaker which converts electric power to acoustic power.
- A device that converts one type of energy to another (e.g., water pressure to electricity, as in a speed recorder; or electrical to acoustic as in a loudspeaker).

- An electrical device that converts a signal from one form of energy to another.
- Any device that is capable of converting energy from one form to another.
- (1) device that converts mechanical energy to electrical output or vice versa. (2) piezoelectric device that converts attributes of the stress-versus-strain field of an acoustic wave into an electrical signal of voltage versus time. sensor; probe. transducer, differential: piezoelectric twin-element or dual-pole transducer.
- Device by means of which energy can flow from one or more transmission systems or media to one or more other transmission systems or media; sensor or probe.4
