The Sentry G3 machinery protection
monitor is a high performance signal
conditioning unit with a universal
sensor interface developed by
Sensonics. G3 systems encompass
vibration, position and speed
measurements, the hardware fault
tolerance of which been
independently verified.

Channel hardware independence is
important for machinery protection
applications where a failure of any
hardware assembly should have a
minimal effect on system measurement
integrity. The four-channel GM
module has independent digital signal
processor for each channel of
measurement. The rack based system
operates on a dual +24V power
supply backplane connected externally
or derived from the optional G3 dual
redundant rack based power supplies.
