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.
