Industrial Low Profile Accelerometers

The OMEGAROMETER Series accelerometers are one of the best accelerometers designed for industrial vibration measurements. These accelerometers feature a hermetically sealed 316L stainless steel case suitable for harsh environments. The ACC787A is a general purpose accelerometer with a low profile side cable exit.

NOTES:
1. To minimize signal distortion when driving long cables or high-vibration signals, 24 to 30 Vdc powering is recommended. The higher-level constant current source should be used when driving long cables.
2. A maximum current of 6 mA is recommended for operating temperatures above 100°C (212°F).
