Data Acquisition Systems
PC-based measurement and control systems provide electrical and physical measurement capabilities for engineers who need a customizable and accurate, yet cost-effective way of conducting benchtop measurements.
Data Acquisition (DAQ) Devices
Data Acquisition is the process of converting real-world physical conditions such as voltage, temperature, current, or pressure into numeric form. A data acquisition system consists of a sensor, measurement device, and software.
In modern practice, Data Acquisition (DAQ) has expanded to include inputs and outputs, analog and digital (discrete) signals, as well as signals collected by communication (USB, Serial) and other means.
Choosing a Data Acquisition System
There are many Data Acquisition platforms, types, and brands to choose from.
The most flexible and widely known family of products is the National Instruments (NI) platform using LabVIEW. It's best feature is that the platform expands far beyond data acquisition into automation and control areas such as industrial instrumentation, machine vision, motion, and much more.
