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 gyro, 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. 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.
