EGAS3 Series Accelerometer

Description: The Model EGAS3 is a cube-shaped, triaxial accelerometer with frequency response to 3500 Hz. Operating from 15 Vdc, this unit features a transverse sensitivity of 2% MAX and damping of 0.7 Overrange stops ensure survivability of the unit under extreme shock conditions wihle its temperature performance offers a minimal zero shift of ± 1 mV per 50°C. With rugged, shielded cables, these units are well-suited for a wide range of high-impact studies.

Features:

  • Small Size
  • Static and Dynamic Measurement
  • Frequency Response through 3500 Hz
