Data Acquisition System By Theta Controls

Acquire data & store on the PC for easy retrieval. Front end can be Data Acquisition modules, PLCs, PID Controllers etc.

Data acquisition systems (DAQs) gather information from one or more signal inputs or sensor sources and process this information for further analysis. These data acquisition systems are mainly means for monitoring and regulating manufacturing processes and systems.

Data acquisition systems are consisting of three main components as shown in diagram above:
Sensors or Transducers: Transducers sense physical phenomena and produce electrical signals that the DAQ system measures.
DAQ Hardware: PC-based data acquisition products offer analog input, analog output, digital I/O, or a combination of these capabilities in a board, card, or module that is designed to interface with a personal computer. The final component of data acquisition systems is a computer that communicates with the DAQ hardware, to collect what information has been measured, display acquired data. Compute it if required, and report generation and data storage can be included in software.

By combining the computational power of the PC with one or more data acquisition boards, cards, or modules, a powerful system can be created:

Acquire data & store on the PC for easy future retrieval.
Acquisition speed can vary from a few minutes to micro seconds.
Front end can be variety of devices, like data acquisition modules, PLCs, PIDs etc.
