Data acquisition devices are a popular choice in data acquisition. To function properly, they need to have a connection with the computer. Another underlying thing that makes them popular is their flexibility. Users can use it in various applications. In the data acquisition process where the analogue information is transformed into digital data, speed is important. To decide the next step, speed helps to make the time more efficient. Accuracy, speed and the flexibility of the tools play the main roles.

Data Acquisition Devices and the Elements of the System
To reach the purpose of the goal of transforming information, there are three elements. The first element as the front line is a sensor. This detects something is coming to the system.
The next element is signal conditioning which will prepare the received information to then pass it to the core of the system that shifts analog information into digital data. This core element is also called ADC which stands for Analog-to-Digital Converter.
Sensor
Also known as a transducer, the sensor is the receiver of the phenomenon. It witnesses the world phenomenon that the data is important to be absorbed. The phenomena are such as movement, force, and temperature.
The sensors that are usually used are those with 3 measurements they are strain gauges (force), and accelerometers (movement) and to measure temperature the sensors are RTDs, thermistors and thermocouples. To have the final great digital data, the sensor should be accurate. Find the sensor with the highest accuracy.
Signal Conditioning
To strengthen the quality of the measurements done by the sensor, signal conditioning is needed as the bridge. Before going to the ADC, the measurements are boosted by this element. Although it is an additional circuitry, the function is important.
However, to decide which signal conditioning, you should check the compatibility with the sensor. Each sensor has different requirements. The temperature sensor needs filtering and amplification/attenuation. Sensor for force (strain gauges) needs calibration, bridge completion and excitation.
ADC
This is the core of the whole system. This comes in the form of a small chip but works properly to transform the raw information of the phenomenon into discrete levels. The processor then interprets that. After that, using software, the data is analysed, visualized and then stored.
In brief, the works of data acquisition devices have four stages: receiving phenomenon through sensor, signal conditioning, conversion and processing.
Data Acquisition Devices in Terms of Monitoring
After knowing the work that also implies the benefits, some industries utilize this device especially those that need it as the monitoring tool. Thanks to the inventor and the developers this tool is versatile with high accuracy. The applications of the device for monitoring are:
Research and Development
This is the source of knowledge. It produces brilliant and beneficial inventions for human civilization. Some experiments need to be thoroughly monitored because of the high-risk level. Engineering, chemistry and physics are three major sciences that their experiments need monitoring with the device.
Medical Service
In this field, the device is related to human life. The level of importance is on the top because the absence of it causes a big danger. ECG is one of the medical equipment that needs thorough monitoring with the help of data acquisition devices. Medical professionals rely on the data to make medical decisions. So, it is intensely related and needed.
Automation Manufacturing
In producing high-quality components, it needs the tools to optimize the whole work and also to monitor the quality. It can track the performance of the equipment which helps the engineer to improve productivity.
Environment
To assess the quality of some important elements such as water and air, the tools provide the information needed. It is then related to the health that can affect the regional government in deciding policy. The tools monitor humidity information, temperature gaps, and pollutants.
After reading the four major sectors, it can be said in other words that the devices are fundamental. Although in some other industries, it might not be as fundamental as what is mentioned above, it is sufficient to conclude that the tools are worth deep consideration.
