Data acquisition is a process where signals or data are sampled from our surrounding real world and digitized for analysis, display, and storage in devices like computers. The signals or conditions for sampling data include temperature, current, voltage, sound, and pressure. To understand this, measuring a room’s temperature using sensors and converting it to a digital value is the best example. The data acquisition system is of two types, like DAS or DAQ, that convert analogue signals into digital data for analysis and processing.
What is a data acquisition system?
A data acquisition system refers to the collection of software and hardware used to measure the physical properties of natural world conditions. The system consists of sensors, actuators, DAQ hardware, signal conditioning hardware, and a DAQ computer running software.
What are the Data Acquisition System (DAS) Components?
A complete data acquisition system consists of components, such as:
- Sensors - convert physical parameters into electrical values.
- Signal conditioning circuitry - transform sensor signals convertible into digital values
- Analogue to digital converters - convert sensor signals (conditioned) to digital forms.
Where is Acquisition Applicable?
The acquisition is used in:
- Research and Analysis
- Manufacturing and Quality Test
- Diagnostic and Repair
- Control and Automation (PC-Based)
- Asset Condition Monitoring
- Design Validation and Verification
What are the Applications of Data Acquisition Systems?
DAS offers various technical product testing and helps enhance productivity by using DAS software to put any sort of data. They have a wide range of applications in industries for:
- Research and development
- Testing and system management
- Process control
- Quality control
- Medical
- Building Automation
- Laboratories.
