Jump down to specs

Watson Industries has manufactured and developed inertial gyro systems since 1980.The company holds numerous patents and is committed to being a leader in the development of angular rate sensing products and systems. The ARS-E332 line of angular rate sensors features our VSG-E series gyros. The VSG gives this angular rate gyro package enhanced performance, reliability and shock survival characteristics.

This sensor system is very rugged. The rate gyros are capable of surviving 500 g's of shock. Various output ranges are available. Watson Industries manufactures other systems including tilt sensors, vertical references, magnetic instruments, magnetic heading systems, as well as two lines of individual gyros.

The triaxial angular rate gyro package provides excellent features:

  • Low Unit Price
  • Good Environmental Performance
  • Analog Voltage Output
  • Available Angular Rate Ranges of 50 to 300° per second
  • Solid State Reliability
  • Two Year Limited Warranty

Applications:

Marine, automotive, antenna stabilization, robotics and many others where accurate measurement of angular rate is required.
