ARS-16 MHD Angular Rate Sensor

The ARS-16 is our most sensitive angular rate sensor, designed to work in a variety of high-performance applications, such as line-of-sight stabilization and precision motion control systems. The ARS-16 can measure angular motions as low as 40 nanoradians, and has low sensitivity to linear acceleration inputs, making it ideal for use in highly dynamic environments such as aerial and ground-based vehicles. The ARS-16 has a wide, usable frequency range from less than 2 Hz to more than 1,000 Hz.

The ARS-16 is designed to be a replacement for our older ARS-14 model. It is designed to provide an improved noise floor and larger temperature range to any application previously utilizing our ARS-14 sensor.

The ARS-16 is designed with a simple screw attachment method, or for applications requiring minimal size and weight, a cylindrical version is available which is designed to be epoxy bonded or clamped in place.
