WebRVDT – It operates 360 degrees but the range of linear operation is + or – 40 degrees. LVDT – Core shape is rectangular. RVDT – Core is cam-shaped. LVDT – Input voltage range from 1V to 24 V RMS. RVDT – Upto 3 V RMS. LVDT – Sensitivity 2.3 mV/V/ degree of rotation. RVDT – Sensitivity 2 to 3 mV/ V/ degree of rotation. A rotary variable differential transformer (RVDT) is a type of electrical transformer used for measuring angular displacement. The transformer has a rotor which can be turned by an external force. The transformer acts as an electromechanical transducer that outputs an alternating current (AC) voltage proportional to the angular displacement of its rotor shaft. In operation, an alternating current (AC) voltage is applied to the transformer primary to energiz…
