View A Video on Data Acquisition Systems - A Quick Introduction

Data acquisition systems are used in order to convert analog waveforms into digital values that can be used for processing. This conversion is possible due to the process data acquisition (DAQ) which is the sampling of actual physical conditions such as property or phenomena, which can include light intensity, fluid flow, gas pressure, temperature and force. The resulting samples are then converted into digital numerical values by means of sensors in order to get all of the data into a unified form that can be utilized by a computer.

Abbreviated DAS, data acquisition systems are both accessed and controlled by data acquisition software programs that utilize a wide range of general-purpose programming languages including Java, Pascal, Lisp and BASIC. Through the utilization of general-purpose programming, instead of industry or application-specific, data acquisition systems are able to be beneficial for a broad spectrum of industries including: medical, for the acquisition of clinical trial data by means such as central web based systems and local electronic data capture systems; industrial, to acquire data through methods such as chart recorders and PC-based systems; aerospace, for the acquisition of data by means including flight data acquisition units and structural dynamics test systems; and wastewater, in order to collect data for information regarding the toxicity of the wastewater and the effectiveness of the treatment.


There are many different components that can be utilized in the manufacturing of data acquisition systems, some of which are essential while others are simply advantageous in certain applications. Some of the essential components include sensors, signal conditioning circuitry and analog-to-digital converters. The sensors are necessary in data aquisition systems because they are the means of conversion of the physical data to the digital values. The signal conditioning circuitry, or signal conditioner, is necessary because it is also a means of conversion. However, instead of functioning in the same capacity as sensors, the signal conditioning circuitry is used to convert the signals from the sensors into a form that is more readily able to be converted into digital values. Lastly, analog-to-digital converters are an essential component of data acquisition systems because they are utilized to finally fully convert the signal after it has been transformed by the signal conditioning circuitry into digital values. Some of the more common uses of data acquisition systems include testing of all kinds for applications such as field studies, troubleshooting and research. Along with monitoring and making appropriate adjustments for processes, manufacturers can test all types of technical products using data acquisition systems.

A variety of components, devices and types of data acquisition systems are available to suit many applications. Some of the more common data acquisition devices include data loggers, temperature recorders and data acquisition cards. Data loggers, also known as data recorders, are defined as being any device with the ability of storing data. Some examples of specific data logging equipment include plug-in boards and serial communication systems. Although they are able to be used as part of a data acquisition system, data loggers are more commonly utilized separately and can even operate without the requirement of a computer. A more specific type of data logger, temperature recorders are utilized for the measurement of the physical phenomena of temperature, which is defined as the degree of either hot or cold of an environment. Temperature recorders can be mechanical, analog or digital, and once converted the information is then downloaded to a computer for usage in applications such as laboratory research and particularly weather stations in order to monitor meteorological conditions. Lastly, data acquisition cards refer to electronic hardware that must be physically plugged into a computer. DAQ hardware is used as an interface between the signal and a computer and the majority must be connected to a computer in order to run, although a small number are able to operate independently.

In addition to a variety of devices and components, there is a broad range of methods in which data acquisition can be achieved. Two common methods in industrial applications are personal computer (PC) data acquisition and universal serial bus (USB) data acquisition. The method of PC data acquisition refers to the vast majority of data acquisition systems and devices that require some sort of connection to a host computer in order to function and properly download the collected information. In fact, there are many types of data acquisition devices that plug directly into the host computer in order to function. One example of this type of data acquisition device is one that uses USB data acquisition. The definition of a USB device is a serial bus that has become standard for connecting and establishing communication between data acquisition devices and a host controller, which is typically a computer. USB data acquisition offers several advantages for DAQ systems including the ability to provide power to peripheral devices as well as offering a higher bandwidth which the capability of reaching 12 Mbits/s. Since USB devices are used in order to supply power, only one cable is required to link the data acquisition device to the computer, which will likely feature at minimum one USB port.

Data Acquisition System Terms

Accuracy - The sum of all factors of error in a data acquisition device.
 
Aliasing - The false reading of high-frequency signals as lower-frequency signals. These readings are expected errors from the discrete calculations with sampling devices like analog-to-digital (A/D) converters.
 
Anti-Aliasing Filter - An apparatus that attenuates the content of signals outside the preferred bandwidth and comes before the analog-to-digital converter (ADC) in instrumentation designs, which, in theory, permits the frequencies only in the pass band to be sampled with the ADC.
 
Analog - A signal that has a value somewhere between two extremes and can constantly change.
 
Analog-to-Digital Conversion (A/D) - The procedure of converting analog signals into a digital value or signal that is then able to be stored on a computer.
 
Asynchronous - Transmission of data between receiving and transmitting mechanisms in the form of zeros and ones. For correct data interpretation, the receiving data needs to start at the appropriate location of the sequence.
