PURPOSE:To simplify structure and reduce manufacture cost by arranging a spherical body which is pivoted rotatably and has large inertial efficiency in a spherical hollow body and flowing fluid. CONSTITUTION:When slightly pressurized fluid is supplied into a fluid input pipe 5, this fluid flows along the circumferential surface of the spherical body 4 as shown by an arrow and is then discharged from a fluid output pipe 6. In this case, the fluid flowing through the upper and lower parts in the spherical body 4 is stationary fluid, so the spherical body 4 holds a fixed state continuously. For example, when an automobile of a system mounting a fluid inertia sensor 1 is turned as shown by an arrow A, the fluid input and output pipes 5 and 6 and spherical hollow body 2 rotate, but the spherical body 4 having the large inertial efficiency holds the fixed state. Then, the fluid becomes unbalanced in flow rate between the upper and lower parts in the spherical body 4 to generate a pressure difference. The pressure difference is detected by pressure sensors 7 and 8 and supplied to a comparator 9. This comparator 9 generates an analog output with the level corresponding to the revolving angular speed. |
