Description
Discontinued
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.

The Pro Gyro® and ARS-G152 series rate gyros have been engineered to meet the specifications of the VSG to serve as a VSG replacement.

The VSG gyro has performed well in a multitude of applications. See our Applications index for an extensive listing of our gyro applications.
