History

The evolution of data acquisition system (DAS or DAQ) manufacturing traces a remarkable path from simple mechanical devices to today’s highly integrated, digital, and IoT-ready systems. This transformation has been shaped by advancements in electronics, computing, sensor technology, and the escalating needs of science, industry, and defense. Understanding this history not only highlights technological progress but also helps buyers appreciate the capabilities and limitations of current DAQ solutions.

Early 20th Century: Mechanical Roots
Initial data acquisition was entirely manual. Technicians recorded process variables—temperature, pressure, and flow—on paper charts using mechanical chart recorders. These analog tools were labor-intensive, prone to human error, and restricted in sampling speed and data longevity.

Mid-20th Century: Analog Instruments Dominate
By the 1950s and ‘60s, innovations like oscillographic and strip chart recorders (notably from Brush/Gould) improved data logging accuracy and speed. These analog DAQ solutions became essential in manufacturing, research, and government projects (including NASA’s space missions). Despite their reliability, analog systems were limited by their bulk, slow operation, and inability to support complex, multivariate analysis.

1960s: Digital Dawn
Computing began to intersect with data acquisition. IBM’s 7700 and 1800 series introduced electronic analog-to-digital conversion, paving the way for digital DAQ. These systems, however, were large, costly, and used mainly in military, aerospace, and government laboratories due to their complexity and price.

1970s: PC Revolution and Democratization
The rise of affordable, general-purpose computers—like S-100 systems—enabled broader DAQ access. Tecmar/Scientific Solutions pioneered plug-in data acquisition cards, making it possible for small businesses and academic researchers to implement high-speed, multi-channel data collection without the overhead of mainframes.

1980s: Digital Integration and Miniaturization
The shift to digital continued, with DAQ hardware adopting microprocessors, digital I/O, and multifunction plug-in cards compatible with ISA or PCI buses. Leading brands included Keithley, Data Translation, and National Instruments. This era saw the introduction of thermal array printheads, high-speed memory, and modular system designs that set the stage for today’s scalable, flexible DAQ architectures.

1990s: PC-Based DAQ and Software Innovation
With the proliferation of Windows PCs, software-centric DAQ became mainstream. National Instruments’ LabVIEW and similar graphical programming environments reduced development complexity and enabled powerful data visualization, processing, and automation. Modular rack systems like CAMAC and VME allowed users to build customized DAQ setups with plug-and-play functionality.

2000s: Networking and Industrial IoT
The DAQ industry embraced Ethernet, USB, and WiFi connectivity, supporting remote and distributed data collection. Industrial Internet of Things (IIoT) applications required rugged, real-time, and high-accuracy DAQ hardware, driving adoption of advanced protocols (CAN, Modbus, MQTT) and centralized control via SCADA systems. Modular DAQ platforms from Dataforth, Keysight, and Siemens offered scalable, cloud-ready solutions for factory automation, energy monitoring, and predictive maintenance.

2010s–Present: Smart, Connected, and Sustainable DAQ
Contemporary DAQ systems feature wireless communication (Bluetooth, WiFi), ultra-low-noise electronics, simultaneous sampling, and seamless integration with cloud analytics. Companies like Dewesoft, UEI, Comptek, Averna, and Sciotex focus on rugged, distributed architectures for harsh environments and remote sensing. Emphasis on sustainability has produced low-power, battery-operated DAQ modules for environmental and geotechnical applications. The global industrial DAQ market continues to expand, driven by the demand for real-time, data-driven decision-making, predictive analytics, and regulatory compliance.

Critical Considerations
While digital DAQ systems offer unmatched power and flexibility, they introduce complexity—cybersecurity, software dependencies, and market consolidation risk stifling niche innovation. Buyers must weigh simplicity, reliability, and long-term support when selecting DAQ solutions for specialized or mission-critical applications.

How It Works

A data acquisition system collects, conditions, digitizes, and processes physical or electrical signals, transforming them into actionable digital data. This process underpins everything from environmental monitoring to industrial automation, and is fundamental to Industry 4.0, smart manufacturing, and advanced research.

Key data acquisition steps:

1. Data Collection: Sensors and transducers detect physical or electrical phenomena (e.g., voltage, current, sound, fluid flow, gas pressure, force, temperature, light intensity).
2. Signal Conditioning: Signal conditioners amplify, filter, and isolate the sensor signals, preparing them for digitization. This ensures high accuracy and noise immunity.
3. Analog-to-Digital Conversion (ADC): Analog signals are sampled and converted into digital values by high-precision ADCs.
4. Data Input and Processing: Digital data streams into a computer or embedded processor, where it is managed, visualized, and archived using specialized data acquisition software.

Data Acquisition Software Programs

Programming languages and development environments for DAQ systems play a critical role in application flexibility, performance, and ease of use:

• LabVIEW: The industry-leading graphical programming environment for rapid DAQ development and intuitive visualization.
• C/C++: Offers direct hardware access, performance optimization, and integration with real-time systems.
• Python: Increasingly used for test automation, data processing, and scripting due to its extensive scientific libraries.
• MATLAB: Popular in engineering, scientific analysis, and algorithm development, with native support for instrument control.
• Java: Noted for platform independence and cross-system compatibility.
• Pascal, BASIC, Lisp: Still used in legacy systems, rapid prototyping, or educational settings.

The optimal programming environment depends on application complexity, hardware requirements, existing infrastructure, and team expertise.
