Low-Cost Charge Amplifier for Piezoelectric Transducers

The Model 4601 Charge Amplifier from Columbia is an affordable, high-Performance instrument that has been specifically developed for general purpose use with piezoelectric transducers for the measurement of force, accelerationand dynamic pressure.

Model 4601 attributes low noise, broad bandwidth, low output offsetand a gain control directly calibrated in transducer sensitivity for a simple setup.
