The Jewell Instruments ASB Series Accelerometer is a general-purpose ±200 radian/second² to ±1000 radian/second² device for industrial, commercial and aerospace sensing requirements. The AS Series of angular accelerometers are solid-state, DC, closed-loop, force-balanced accelerometers with accuracy, reliability several orders of magnitude greater than open-loop types. They are ideally suited to the precise requirements of inertial guidance and control systems. These are pendulous devises, balanced for angular acceleration.

It follows that angular acceleration applied to an accelerometer and acting on a rotatable bearing-mounted balanced mass will develop a torque about the axis of rotation. By arranging the mass so that any resultant motion develops an electrical signal which is properly amplified and supplied to an electrical torque generator acting on the mass, equilibrium is produced between the two torques.

Applications of the Jewell Instruments ASB Series Accelerometer include:

  • Antenna stabilization
  • Torque measurement and control of motors
  • Automotive angular acceleration testing
  • Optical system stabilization
