These transducers are employed in factory environments on automated operating machines, on counting, display and control systems, for \u201ccut to length\u201d positioning, for certain pitch displacements and, more in general, to display measures of length and thickness.<\/p>\n<h4>Potentiometric linear transducer<\/h4>\n<p>This type of linear transducer is formed by a wire or a metal layer, winded up in a non-conductor support, and by a movable contact that shifts along the conductor. The operating principle is based on the\u00a0<strong>change in resistance<\/strong>\u00a0of an electric circuit, caused by the displacement of the object of which the position must be determined. Potentiometers are particularly suitable for the employment in thermoplastic, wood, marble, iron and steel processing machinery and for any application that requires position and motion absolute measurement.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-408\" src=\"https:\/\/eltra.bfenterprise.it\/wp-content\/uploads\/2026\/03\/Potenziometrico.png\" alt=\"Trasduttore lineare potenziometrico\" width=\"770\" height=\"323\" srcset=\"https:\/\/eltra.bfenterprise.it\/wp-content\/uploads\/2026\/03\/Potenziometrico.png 770w, https:\/\/eltra.bfenterprise.it\/wp-content\/uploads\/2026\/03\/Potenziometrico-300x126.png 300w, https:\/\/eltra.bfenterprise.it\/wp-content\/uploads\/2026\/03\/Potenziometrico-768x322.png 768w, https:\/\/eltra.bfenterprise.it\/wp-content\/uploads\/2026\/03\/Potenziometrico-600x252.png 600w\" sizes=\"auto, (max-width: 770px) 100vw, 770px\" \/><\/p>\n<h4>Magnetostrictive linear transducer<\/h4>\n<p>Magnetostrictive transducers are based on the\u00a0<strong>magnetostriction principle<\/strong>, for which certain materials expand and contract when they are put into an alternate magnetic field.
