Model 8000-4226 Four Channel Charge Amplifier
PBS-4100 Balancing System Accessories
The Model 8900-4226 Four
Channel Charge Amplifier is
used to convert accelerometer
charge signals into voltage
signals. Converted signals are
then easily used by the PBS4100 family of engine
vibration analyzers.
Conversion of signals to
voltage-mode provides
greater immunity to noise and
allows signals to be reliably
transmitted over greater
distances.
The charge amplifier is normally
installed at the engine. It is not needed
if another charge amplifier is already
present (as part of aircraft or test cell
equipment) or where velocity probes are
used instead of accelerometers.
