The model 6634C vibration amplifier is a microprocessor-based instrument designed to condition and
display vibration data from rotating machinery. The instrument accepts inputs from a single-ended,
differential PE or ISOTRON® accelerometer, velocity coil, or remote charge convertor. Full scale AC
and DC output ranges are programmable in user selected engineering units to represent either
acceleration, velocity, or displacement. Programming of the unit is accomplished from the front panel
keyboard or optional RS-232 computer interface. Up to ten different setups can be stored and recalled
from the non-volatile memory. An optional 6 pole filter is available, which may be programmed from
the front panel. There are two TTL compatible latched alarm outputs provided for warning and alert.
