8-channel data acquisition system
High-precision Sound & Vibration Measurements
The MB DAQ 8256 is an advanced eight-channel data acquisition system designed for high-precision, multi-channel sound and vibration measurements, Squeak & Rattle testing, and in-line acoustic test systems.
The system features universal inputs that accommodate voltage sensors, IEPE accelerometers, and microphones, as well as additional measurements like temperature, displacement, position, or pressure through current sensors with a 4-20 mA output.
Equipped with a delta-sigma A/D converter, the MB DAQ 8256 allows for simultaneous sampling at rates up to 256kS/s per channel. With a signal-to-noise ratio of up to 107dB, minimal distortion, and very low phase deviation between channels, this data acquisition system ensures noise- and distortion-free recording of even the smallest signals in challenging industrial settings. Additionally, it includes four digital inputs for capturing frequency, speed, pulse width, and quadrature encoder signals. A robust signal processor enables pre-processing and analysis of the collected data. The built-in Ethernet port facilitates data streaming for further analysis and visualisation using the BSR SUITE data acquisition software, which is ideal for Sound & Vibration analysis, NVH, and Squeak & Rattle testing.
