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.
