Grab Bag of Data Acquisition Solutions
Web-based, higher speed and accuracy, smaller and less expensive, open architectures.
In a PC-based data acquisition tutorial produced by National Instruments, the company explains “that data acquisition involves gathering signals from measurement sources and digitizing the signal for storage, analysis and presentation on a PC. DAQ systems come in many different PC technology forms for great flexibility when choosing your system Scientists and engineers can choose from PCI, PXI, PCI Express, PXI Express, PCMCIA, USB, IEEE 1394, parallel, or serial ports for data acquisition in test, measurement and automation applications. There are five components to be considered when building a DAQ system: transducers and sensors; signals; signal conditioning, DAQ hardware, and driver software.”
“Data acquisition begins with the physical phenomenon to be measured. The transducer is the device that converts a physical phenomenon into a measurable electrical signal, such as voltage or current.
The appropriate transducers convert the physical phenomena into measurable signals, either digital or analog.
- Signal Conditioning
Sometimes transducers generate signals to difficult or too dangerous to measure directly with a DAQ device. Signal conditioning maximizes the accuracy of the system, allows sensors to operate properly and guarantees accuracy.
- DAQ Hardware
DAQ hardware acts as the interface between the computer and the outside world.
- Driver and Application Software
Software transforms the PC and the DAQ hardware into a complete data acquisition, analysis and presentation tool.”
There are many supplier who provide the complete bundled PC-based data acquisition systems and others that supply the parts. It largely depends on your application what choice you make.
In the future, Bill McGovern, National Sales Manager at Dataforth Corp. feels that “smaller, inexpensive and networked are the three words that can summarize the future of industrial data acquisition systems. Already, there are “shoe-box” sizes and small “6 in. cube” sized DAQ products available and sell for less than $1000.
Soon, you will see instrument quality DAQ products in a 5 in. x 7 in. x2 in. wide package that can be networked via Ethernet TCP/IP or Modbus TCP/IP. These new products will create a “DAQ Appliance” where you simply access the data from anywhere using its IP address.”
James Gau, V.P. ADLINK Technology sees “data acquisition technologies continue to exhibit on-going advancement in three areas: speed, accuracy and cost. Yet development for the further progress is met with many challenges. For example, as signal frequencies climb, distortion and bandwidth limitations on front-end circuits becomes the primary factor affecting high speed data acquisition; amplifiers and high resolution A/D conversion can only improve the accurate measurement of small signals when algorithms for noise elimination advance; and FPGA devices can be designed to incorporate more functionality to reduce component count, and thus reduce costs.”
This Product Roundup shows a variety of products that can perform the data acquisition function, from Web-powered data logging to wireless remote monitoring devices. Technologies are shifting fast in the data acquisition and recorder marketplace. With this kind of competition, we are bound to see some very exciting announcements.
