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).
- Первичный измерительный преобразователь, датчик
- A device that converts energy from one form to another, such as a microphone or speaker.
- 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
- (1) device that converts mechanical energy to electrical output or vice versa. (2) piezoelectric device that converts attributes of the stress-strain field of an acoustic wave into an electrical signal of voltage versus time. sensor; probe.16 transducer, differential: piezoelectric twin-element or dual-pole transducer, the output poles of which are isolated from the case and are at a floating potential.16

Filament transformer (rt), английский
A transformer supplying power to heat the filament of a hot-cathode. the primary and secondary windings must be sufficiently insulated to withstand the peak potential difference between the cathode and earth.
Angle transducer (ut), английский
A transducer used in angled testing in which the sound beam is set to some predetermined angle to achieve a special effect, e.g., setting up shear or surface waves in the tested piece.
