A device for measuring the frequency of vibrations on a tight drive belt and a method for carrying out the vibration frequency measurement

摘要

Device (1) for manually measuring the frequency of vibrations on a tight drive belt (6, 6′, 6″), comprising a Doppler radar module (3) which uses a transmit antenna (4) for emitting a transmit beam (8) onto a vibrating surface of the drive belt (6, 6′, 6″) as well as a receive antenna (5) for receiving the receive beam (9) reflected by the surface and evaluates the receive beam (9) according to the Doppler principle, the vibration sensor (1) also comprising an acceleration sensor (10) in addition to the Doppler radar module (3), the signals of the acceleration sensor (10) being calculated along with the signals of the Doppler radar module, thus allowing some signals to be disregarded.
