The MFPA-VVS is a 1-channel signal conditioner is especially designed for our Volume Velocity Sources. The MFPA-VVS main usage is to power and amplify the received particle velocity signal to 1 channel line level BNC output. However with the MFPA-VVS there is more, thanks to its build-in correction its provide a flat, corrected output. Enabling compatibility and ease of use with most common use sound and vibrations software's.
- Programmable conditioning unit
- USB to connect and program VVS parameters
- Flat, corrected output enabling 3rd party compatibility
- Compatible with both MHVVS and LVVS
MFPA-VVS integrates a bank of programmable filters before the pre-amplification stage of the traditional MFPA. The filtering stage (2 high-pass and 2 low-pass filters) compensates the natural frequency-dependent sensitivity of particle velocity sensors, achieving a broadband correction at the output of the MFPA-VVS for the entire frequency range. The corner frequencies of the filters can be adjusted by the manufacturer every time the sensor (VVS source) is calibrated. Please be aware that the MFPA-VVS has to be exclusively used with one single volume velocity source, and therefore this pre-amplifier is not interchangeable.
