Description

The ARS-G152 is Watson’s newest addition to its line of rate gyro sensors.

Watson Industries has been designing and manufacturing solid-state gyros since 1980. The ARS-G152 Rate gyro has many of the features from our Pro Gyro® line but includes many exciting new capabilities including digital output and several analog output ranges. Users can still take advantage of this gyro’s built-in test feature and enhanced EMI/RFI protection.

The ARS-G152 has excellent performance for stability, acceleration insensitivity, and vibration rejection. This is achieved by having a sensing element that is finely tuned and temperature compensated. Other significant advancements have been made on the ARS-G152. A menu system allows for adjustable sensor bandwidth. The analog rate output can also be toggled between unipolar and bipolar using menu adjustments.
