Abstract
A vibration sensing and measuring system is disclosed as including a series connected signal generator, vibration sensor adapted for being connected to any appropriate compatible object from which the vibration information and/or parameters analogous thereto are desired, and utilization apparatus - such as, for example, a readout - for indicating or otherwise utilizng the measured vibrations of said vibrating apparatus. When the aforesaid object vibrates, said sensor vibrates in synchronism therewith; thus a liquid disposed therein is disturbed in such manner as to cause standing waves at the surface thereof that are proportional thereto. The reception by a photodiode (located in said sensor) of light broadcast in a given amount along and in contiguous disposition with the surface of said liquid by a light emitting diode (likewise located in said sensor) is reduced in accordance with the aforesaid standing waves thereof and, by calibration, constitutes a measure of the vibration of said sensor and, hence, the object to which it is connected.
