Low-Pass Filter; High-Pass Filter - HBM PACEline CMD600 Manuel D'emploi

Sensor
Example:
CFT piezoelectric force
transducer
Only high-insulation connection cables (1−KAB143−3, see accessories) that
generate little friction electricity may be used for piezoelectric sensors.
The CMD600 charge amplifier is designed for direct voltage operation
(18 ... 30 V). The circuit is intended for operating with separated extra-low
voltage (SELV circuit).
NOTE
If a sensor has ground insulation or if there is an electrically isolated feed, we
recommend grounding the charge amplifier housing. The amplifier inputs and
outputs are electrically isolated.

3.6.3 Low-pass filter

In many cases it is necessary to filter the measurement signal with a low-pass
in order to eliminate, e.g. interfering noise components.
An internal low-pass filter can be connected to the CDM600. The freely
adjustable values lie between 1 Hz and 30 kHz.

3.6.4 High-pass filter

The charge amplifier has an internal connectable high-pass filter (0.15 Hz and
1.5 Hz). This minimizes lower-frequency interferences (drifting).
