Description
Discontinued Product
The Vibrating Structure Gyro is a solid state rate sensor that is designed around a piezoceramic cup that can measure coriolis force. This allows the VSG to produce a highly accurate output that is proportional to the rate of turn. Electronics for filtering, control, drive and demodulation are all packaged along with a single axis sensing element inside a small housing. Wide input rate ranges (up to 3000° per second) are available. Unipolar or bipolar output voltage configurations are available as well.
Principles of VSG Gyro Operation – See some of the science behind how the VSG gyro works.
The Pro Gyro® serves as a VSG replacement. The Pro Gyro® series rate gyro has been engineered to meet the specifications of the VSG.
