771 Hermetic Variable Capacitance Accelerometer

New hermetically sealed DC accelerometer for aerospace vibration measurement

IRVINE, Calif., USA – Mar 8, 2018 – Meggitt Sensing Systems, a division of Meggitt PLC, has released the Model 771 variable capacitance accelerometer for aerospace and military applications. The hermetically sealed, stainless steel housing ensures accurate and stable measurements over many years, while the DC response of the 771 is critical for accurate integration calculations.

This sensor excels at measuring low level accelerations immediately after a shock and its rugged design provides 10,000 g shock survivability. The 771 can also operate from -55 to +125 °C, compliant with many aerospace and military test specifications.

Key features:

- 2, 10, 30, 50, 100 and 200 g ranges

- Easy to install 0.625 inch hex base

- Flat frequency response up to 1,500Hz

- 7 to 36 V input voltage; “R” option for 5 V operation

- Single-ended output

Materials of construction are CE and RoHS compliant.  Each unit is tested, custom-packaged and shipped with its own calibration certificate and a 10-32 mounting stud.  Optional mounting studs are available as is the rugged 3027A cable that was specifically designed for shock and vibration environments.
