Alfa Centauri

Charge Amplifier for mASTRO system

The charge amplifier is designed for piezoelectric sensors (pressure, accelerometer, ecc) and for on-board application.
The mASTRO system can host up to 10 Alfa Centauri modules, to optimize the space utilization based on the application. Modules can be added at any time.
Alfa Centauri is designed for a wide variety of sensors with different sensitivities. Thanks to internal active electronics, Alfa Centauri supports an input range from 100pC to 28000pC. The typical application is for monitoring in-cylinder pressure of engines, especially in those applications where compactness is required (i.e. on-board vehicle and racing use).
A dedicated software is provided to configure sensor sensitivity and output amplitude for each channel. It’s also possible to configure output offset, filter, time constant and output type. The time constant is configurable, including auto drift compensation to reduce signal error and saturation problems.


Key Features
