Acquisition centres
Data acquisition systems gather and synchronise measurements from electrical, mechanical or thermal sensors to record changes in physical quantities over time. These multi-channel systems, which are modular and scalable, offer resolutions of 16 to 24 bits and sampling speeds of up to several MS/s per channel. In R&D, they are used to characterise prototypes, measure transient responses or validate control laws. In production, they monitor critical process parameters such as temperature, pressure, current, vibration or rotation speed. Modern models incorporate digital pre-processing, adaptive filtering and conditional triggering functions. Synchronisation via GPS, IEEE-1588 or IRIG-B guarantees the temporal consistency of distributed measurements. For maintenance, they provide long-term drift monitoring and performance diagnostics. Ethernet, USB and Wi-Fi interfaces enable local or remote operation, with CSV, HDF5 or standardised formats available for export. Used in the energy, aeronautics, research and mechanical test bench sectors, they are at the heart of synchronised, traceable measurement.

concrete questions about central purchasing units
01
What is the role of a central purchasing unit?It is used to collect, digitise and store data from analogue or digital sensors. Temperature, pressure, vibration, voltage, current or logic signals can be recorded simultaneously, on several synchronised channels.
02
In what contexts are these systems used?In mechanical or thermal testing, on engine test benches, for vibration analysis, prototype validation, electrical network monitoring or on-board equipment qualification. They are also used in critical infrastructures for long-term recording.
03
What are the differences between a datalogger and a data logger?The datalogger is more modular and scalable, with more inputs, sampling rates, configuration flexibility, and often a complete software package for advanced processing. The recorder is simpler, sometimes stand-alone, field or maintenance oriented.
04
What should I look at before buying?Number of channels, sensor compatibility (thermocouple, RTD, bridge, ICP), input resolution, triggering capabilities, sampling speed, storage and external synchronisation options (GPS, IRIG, PTP).
05
Is specific software needed to process the data?Yes, most dataloggers come with a software environment dedicated to acquisition, real-time display and analysis. Some formats can be exported (CSV, TDMS, MDF), but compatibility with your existing tools needs to be checked.
