Charge Amplifier-System MCPA 10
Müller Charge Amplifier-System MCPA 10
For In- and Outdoor Experiments with Piezoelectric Sensors Bandwidth 100 Hz to 10 MHz
Typical Applications
This unique amplifier was designed for shock and blast wave measurements as well as for
amplification of any dynamic pressure changes. With its broad bandwidth from 100 Hz to
10 MHz it can exactly reproduce any pressure waves in shock tubes as well as in the field.
The system comes with two independent devices, the “Charge Driver” and the “Power
Supply & Amplifier”. The “Charge Driver” can drive long extension cables up to 150 m and
is positioned close to the sensor. The Amplifier is connected directly to the recorder, needs
an external 12 V power (incl.) and supplies the “Charge Driver”. It is adjustable with a x1 or
x10 amplification. The system is designed water protected for outdoor experiments.
This amplifier is ideal for high frequent piezoelectric sensors like our Müller-Platte Needle
Probe or the pressure transducers M60 as well as for all other piezoelectric sensors.
