1. Application
The Signal Conditioners of M68 series are intended for
connection of piezoelectric acceleration, force or pres-
sure transducers. The input is suitable for sensors with
charge output as well as for ICP
®
compatible transduc-
ers or microphones.
By means of the M68 the sensor signal can be best
possibly adapted to the existing measuring equipment or
PC-based data acquisition systems. The Signal Condi-
tioners provide the following functions:
•
Adaptation of the sensor signal and sensor supply
•
Amplification
•
High- and low-pass filtering (for example anti-
aliasing filter)
•
Integration of the sensor signal, for instance, to
measure velocity or displacement.
Models M68D1 and M68D3 are housed in a rugged
aluminum case. Both models can be used in laboratory
as well as under field conditions. Model M68D1 may
also be operated from batteries. Model M68R1 has been
developed for multichannel measuring systems. It fits
into 19”-rack systems.
