CA1800 Charge Amplifier System
The CA1800 Charge Amplifier System conditions and amplifies
charge-mode accelerometer signals. It is a rugged, rackmountable instrument designed to be used engine test cell
control rooms and other environments where charge-mode
accelerometers are used to measure machinery vibration.
The CA1800 Charge Amplifier System provides up to eight (8)
channels of charge amplification. Each charge amplifier
provides a buffered acceleration output signal as well as an
integrated (velocity) signal output. Outputs may be
configured for either differential or singled ended
configurations, and each channel may be configured (at the
MTI Instruments factory) for one of three different gain
settings to match accelerometer sensitivities.
