The Dual Mass Flywheel (DMF) is used in many modem vehicles to decrease noise and absorb vibration on the move. By the two decoupled masses of the flywheel are linked by spring dampers, torsional vibration can be reduced. The measurement of angular displacement of DMF is very important to analysis power transmission characteristics between the engine and the transmission. To get the real time displacement data of DMF, sensor based on the principle of LVDT is mounted on rotating flywheel. The power for circuit is supplied using a method of electromagnetic induction. In addition Bluetooth technology is used for wireless data transmission.
