Abstract
The present invention relates to an apparatus for measuring pressure inside a vessel using a magnetostrictive acoustic transducer. The apparatus includes a magnetostrictive acoustic transducer, including an exciting coil unit wound on a first magnetization yoke disposed on an outer position of a vessel, a receiving coil unit wound on the first magnetization yoke, and a vibration unit disposed on an inner position of the vessel in which the first magnetization yoke is installed; a control unit for supplying a predetermined excitation current signal to the exciting coil unit; and a pressure measuring unit for measuring an internal pressure of the vessel based on an ultrasonic wave signal received by the receiving coil unit and an excitation current signal into the exciting coil unit.
