Principle of operation

CMD charge amplifier
Fig. 7.1 Block diagram for the CMD measuring chain
The CMD charge amplifier is connected to a transducer
for signal conditioning. The CMD amplifies the electric
charges to a proportional output signal of ‐10 ... +10 V
(see the manufacturing certificate for accurate data).
The RESET/MEASURE input can be used to trigger
measurement, or to clear (RESET) the charge amplifier
input capacitors.
The charge amplifier is fitted with TEDS (Transducer
Electronic Data Sheet).
