8 CHANNEL CONDITIONING UNIT MCAV 01
for piezoelectric accelerometers

mcav01.jpg (15443 octets)

The MCAV 01 conditioning unit contains 8 identical measuring channels.
Every channel consists of a charge amplifier, followed by a remote-controlled gain
differential output amplifier and a remote controlled low-pass filter.
The large charge amplifier setting range allows the use of most
piezoelectric accelerometers.
The differential output is designed for connection to a data acquisition
system by simple twisted pairs or flat cable up to a distance of approximately 30 meters.

PIEZOELECTRIC ACCELEROMETER PAC/20/M

pac20m.jpg (18731 octets)

The accelerometer type PAC/20/M is a waterproof piezoelectric pick-up.
The pick-up is designed around a low mass armature on which is fixed a
ceramic cantilever the stress of which provides the charge generation.
A 5 meters long low noise cable connects the accelerometer to the charge amplifier.
