PURPOSE:To measure efficiently the oscillation of various rotary machines with a single device by incorporating oscillation measuring means such as an acceleration sensor, dynamic electricity type sensor, and displacement gauge, a data swtching means, and a recording means in the same housing. CONSTITUTION:The output of the acceleration sensor is inputted from an input terminal 7, and a changeover switch 15 selects an acceleration speed, oscillation speed, or oscillation displacement when necesary; and effective values or peak values of those signals are displayed on display devices 17 and 19. This signal is selected by a changeover switch 38 or 39 and recorded by the frequency modulation type or direct recording type recording circuit of a data recorder. The output of the dynamic electricity type sensor is inputted from an input terminal 20, and a changeover switch 26 selects an oscillation speed or oscillation displacement. Further, the output of the displacement sensor is inputted from an input terminal 31 and an AC or DC displacement signal corresponding to the distance from an object of measurement is selected with a switch 35.
