<P>PROBLEM TO BE SOLVED: To provide a method and a device for testing fluid pressure that do not require provision of a testing means for each fluid pressure system, and can reduce a component cost by testing fluid pressure in a fluid pressure system from the outside thereof. <P>SOLUTION: The fluid pressure of the fluid pressure system is provided with an accumulator including a cylinder and a piston housed in the cylinder and configured so that the piston slides in the cylinder while compressing gas filled in the cylinder by the fluid pressure in the fluid pressure system. The fluid pressure of the fluid pressure system is tested by abutting an ultrasonic sensor 11 on the outer peripheral surface of the cylinder in the accumulator and displaying a detected response waveform on a display unit 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
