Obsolete
	The ARS-01 is our most rugged angular rate sensor. Originally designed for automobile crash and aircraft ejection testing, the ARS-01 has become a standard for the world's major automotive manufactures and test laboratories, and is equally versatile for use in torsional analysis, motion and vibration sensing and control, and aerospace applications. Durable enough to survive years of crash tests, it is available in two standard models: the ARS-01 and the ARS-01S. The frequency response of the ARS-01 products comply with SAE J-211 Class 1000 frequency response specifications. The ARS-01 and ARS-01S require use of the CA-01 cable assembly.

Notes:

1. Based on a ± 10V output voltage swing.

2. Based on a ± 3.5V output voltage swing.

3. Measured @ 10 Hz.

      4. The standard frequency response of MHD sensors
          can be extended significantly by the use of digital
          filtering in post processing of signal data as
          covered in ATA Sensors' application note AN-01.

5. Power spectral density flat to angular velocity over
specified bandwidth.

6. Percent change in Scale Factor per ºC @ 10 Hz.

       7. Signal return connected to case (isolated from hex
           base). Do not ground case to mounting fixture to
           avoid ground loops.
