Options
The OMEGAROMETER™ Series
accelerometers are designed for
industrial vibration measurements.
They feature a hermetically sealed
316L SS case suitable for harsh
environments. The ACC797 is a
high-performance model with a
side cable exit. FM and CSA
intrinsic safety approval is an
available option.

NOTES:1To minimize signal
distortion when driving long
cables with high-vibration
signals, 24 to 30 Vdc powering
is recommended. The higherlevel constant current source
should be used when driving
long cables; please consult

Sales.
A maximum current
of 6 mA is recommended for
operating temperatures above
100°C (212°F).
