Pro Gyro™
Professional Grade Gyro
Description:
Watson Industries has been designing and making solid-state
gyros since 1980. They have now produced a new series of rate gyros, the Pro
Gyro™. This breakthrough new gyro is built, using a monolithic
piezoceramic resonator and patented circuitry, to be a
VSG replacement and much more.
Based on proven technology, this gyro is built under AS9100 quality standards
with new features including built-in test and enhanced EMI/RFI protection.
The Pro Gyro™ has best-in-class performance for
acceleration insensitivity, low mounting sensitivity and excellent vibration
rejection. This is achieved by having a much larger sensing element that is
solidly mounted. The larger element allows better relative tolerances for
tuning and better signal to noise performance. Solid mounting holds the gyro
sensing element in a stable alignment. In contrast, all the competitive MEMS
gyros use sensing elements that are supported by thin filaments as springs that
are resonant at disturbingly low frequencies. These springs allow the sensing
element to shift and resonate under shock and vibration, which affects their
performance significantly.
Upgrades that are standard for the Pro Gyro™ include
available rate ranges up to 3000 degrees per second, internal power regulation
for power input between 9 volts and 35 volts, and a case mounted connector.
