The invention relates to an installation for calibrating linear transducers, provided with a laser interferometry measuring system and a computing system. According to the invention, the installation comprises an assambled bed frame (1) whereon a measuring table (2) made of andesite is placed, the installation being provided with an orienting and fastening subassembly (3) meant for positioning the transducer for calibration, two andesite guideways (4) along which a measuring probe (5) is travelling, said measuring probe being driven by a travelling driving system which is made using a motor-reducer-ball-screw subsystem (6), by means of a special coupling for the non-vibratile transmission of the travel to the measuring system comprising the measuring probe (5) and a laser interferometer (8) located on an orientable support (7). The claimed installation also has a computing system comprising a computing equipment (9) provided with displaying and editing functions and with a protocole for performing the measurments, and a subassembly of electronic units (10) having the function of electro-pneumatic control. Invenţia se referă la o instalaţie pentru etalonare traductoare liniare, echipată cu un sistem de măsurare prin interferometrie laser şi un sistem de calcul. Instalaţia conform invenţiei este formată dintr-un batiu asamblat (1), pe care este amplasată o masă de măsurare (2) din andezit, instalaţie prevăzută cu un subansamblu de orientare şi fixare (3) pentru poziţionarea traductorului în vederea etalonării, două ghidaje (4) din andezit, pe care se deplasează un cap de măsurare (5) acţionat de un sistem de acţionare a deplasării, realizat cu un subsistem motor-reductor-şurub cu bile (6), prin intermediul unui cuplaj special de cuplare pentru transmisia fără vibraţii a deplasării la sistemul de măsurare, format din capul de măsurare (5) şi un interferometru cu laser (8), aşezat pe un suport orientabil (7). Instalaţia presupune şi un sistem de calcul ce cuprinde un echipament de calcul (9) prevăzut cu funcţii de afişare, editare şi protocol de efectuare a măsurătorilor, şi un subansamblu de blocuri electronice (10) cu rol de comandă electropneumatică.
