transduktori

Transduktori is a term used in several languages to denote a transducer, a device that converts energy or information from one form into another. The word corresponds to the English "transducer" and has roots in the Latin transducere, meaning "to lead across."

Functionally, a transduktori can operate as a sensor, converting physical phenomena (such as pressure, temperature, force, or light) into electrical signals, or as an actuator, transforming electrical signals into mechanical motion, sound, or other physical effects. Common examples include microphones, which convert sound to electrical signals, speakers, which perform the reverse, strain gauges, thermocouples, piezoelectric elements, and optical-to-electrical photodetectors.

Transduktori types are often categorized by the domains they connect: mechanical-electrical, acoustic-electrical, optical-electrical, chemical-electrical, and bio-electrical. Key performance parameters include sensitivity, range, linearity, bandwidth, response time, resolution, impedance, and stability. Proper operation frequently requires signal conditioning, amplification, filtering, and calibration to ensure accurate and reliable measurements or actuation.

Applications range across instrumentation, medical devices, industrial automation, telecommunications, consumer electronics, and scientific research. Standards and calibration protocols exist to quantify uncertainty and maintain interoperability. In engineering practice, the distinction between sensor, transducer, and actuator can blur, but all share the common role of mediating between different physical or information domains.
