A data acquisition (DAQ) system collects and converts physical or electrical signals like voltage, temperature, or pressure into digital data for analysis. It helps engineers and technicians monitor, measure, and troubleshoot systems in real time.
A typical DAQ setup includes sensors, signal conditioning hardware, a digitizing interface, and software to record and interpret the data. These systems are used in labs, production lines, and field environments to ensure accuracy, safety, and performance across many applications.
Choosing the right data acquisition system starts with understanding your application and measurement needs. Consider the number of input channels, the type of signals you're measuring (such as voltage, current, or temperature), and the required sampling rate and resolution.
Also think about:
The type of connection you need (USB, Ethernet, PCI)
The environment where the system will be used (lab or field)
Compatibility with your software and existing equipment
Flexibility to expand the system in the future
ValueTronics offers a wide range of options to support everything from basic measurements to complex, multi-channel setups. Our team is here to help you find the right fit.
Signal conditioning is the process of preparing a signal for accurate measurement by a DAQ system. It involves modifying the signal so it fits within the proper range and format for the data acquisition hardware. Common signal conditioning functions include amplification, filtering, isolation, and conversion.
This step is important because raw signals from sensors can be weak, noisy, or incompatible with the input range of the DAQ device. Proper conditioning improves measurement accuracy, protects equipment, and helps maintain consistent, reliable data collection.
Meters are often used alongside DAQ systems to perform precise, standalone measurements or to validate data from automated setups. Common types include:
Digital Multimeters (DMMs): Measure voltage, current, and resistance with high accuracy. Often used for calibration or spot-checking.
LCR Meters: Measure inductance, capacitance, and resistance, especially useful in component testing.
Power Meters: Monitor energy usage, efficiency, and load behavior in AC and DC systems.
Temperature Meters: Capture readings from thermocouples, RTDs, or infrared sensors in thermal testing environments.
These meters can complement DAQ systems in both bench and field settings, offering added flexibility and validation during data collection.
The main difference between static and dynamic DAQ systems lies in the type and speed of the signals they measure.
Static DAQ systems: Designed for slowly changing or steady-state signals like temperature, pressure, or voltage. These systems typically require lower sampling rates and are ideal for long-term monitoring or control applications.
Dynamic DAQ systems: Built to capture fast, time-varying signals such as vibration, sound, or high-speed electrical events. They use higher sampling rates and specialized hardware to handle rapid signal changes with precision.
Data acquisition systems are used across a wide range of industries where accurate measurement and monitoring are critical. The most common include:
Aerospace and Defense: For structural testing, environmental simulation, and avionics validation.
Automotive and EV: Used in performance testing, battery monitoring, and vehicle diagnostics.
Semiconductor: For high-speed data logging, process control, and equipment testing.
Education and Research: Supporting lab experiments, teaching, and engineering research projects.
Industrial Manufacturing: Used in quality control, machine monitoring, and automation systems.
