Angular Rate Gyro ARS-C332-3A (Triaxial)

This angular rate gyro package contains three Watson ARS gyro sensors. The ARS-C332 is an analog gyro package that gives an output voltage proportional to the rate or turn along its sensitive axis. The triaxial configuration allows measurement of roll, pitch, and yaw rate simultaneously.

Watson Industries has manufactured and developed inertial systems since 1980. The company holds numerous patents and is committed to being a leader in the development of inertial products. The ARS-C332-3A is a miniaturized version of the ARS-E332-3A. This sensor uses a set of smaller gyros to reduce the size of the package.

The triaxial angular rate sensor is capable of surviving 500 g’s of shock. Various output ranges are available. Watson Industries manufactures other systems including angle sensing devices, magnetic instruments, magnetic heading systems, as well as a complete line of individual gyros.

The ARS-C332-3A has applications in automotive, medical, antenna stabilization, robotics and many others where accurate measurement of angular rate is required.
