Abstract:
A device for measuring a vibration frequency of a mechanically vibrating string or rod, comprising a microwave transmitter for directing microwaves towards the vibrating string and a microwave receiver for receiving the microwaves amplitude modulated by the frequency of mechanical vibration. A member is arranged close to a vibration maximum of the vibrating string. The member is arranged on one side of the vibrating object and the microwave receiver is arranged on the other side thereof. The device is used for measuring temperature, pressure, torque, force or identity.
