Müller Charge Amplifier-System MCPA 10

For In- and Outdoor Experiments with Piezoelectric Sensors Water Protected Application – Bandwidth 100 Hz to 10 MHz

Typical Applications
This amplifier was designed for shock and blast wave measurements using long extension cables as well as for amplification of ultrasound waves. With its broad bandwidth from 100 Hz to 10 MHz it can exactly reproduce any shock or pressure waves in shock tubes as well as in the field.
The system is designed water protected for outdoor experiments. On request we provide the Charge Driver water tight for under water experiments. This amplifier is ideal for high frequent piezoelectric sensors like our Müller-Platte Needleprobe or the pressure transducer Müller M60 as well as for all other piezoelectric sensors.
The system comes with two independent devices, the “Charge Driver” and the “Power Supply & Amplifier”. The “Charge Driver” can provide long extension cables up to 150 m and is positioned close to the sensor. The “Power Supply & Amplifier” is connected directly to the recorder, needs an external 15 V power and supplies the “Charge Driver”. It is adjustable with a x1 or x10 amplification.
