Bridge Structural Monitoring System

Data Acquisition > Ethernet > Distributed Synchronous The collapse of the I-35W Mississippi River Bridge in Minneapolis, Minnesota on August 1, 2007 was a calamity of huge proportion. Carrying over 135,000 vehicles daily, the bridge failed during the evening rush hour resulting in thirteen fatalities and 145 injuries. Almost immediately plans were formulated for a Read More

Intelligent Oversampling Enhances Data Acquisition

Data Acquisition > Software > WinDaq Editor’s note: Watch our YouTube videos for in-depth Intelligent Oversampling demonstrations.  Intelligent Oversampling  pays dividends in so many applications, especially in terms of noise reduction, that it’s difficult to think of an application that wouldn’t benefit. Did you ever wish you could have your cake, and eat it too? In Read More

Data Acquisition in Microsoft Excel—How to Import Recorded Data

Data Acquisition > Software > WinDaq > WinDaq/XL In our experience, Microsoft Excel is the most popular application for waveform analysis. Our customers ask about porting waveform data to Excel more so than all other applications combined. In response, DATAQ Instruments’ developed WinDaq/XL to allow users of WinDaq software (both recording and playback software) to Read More

DI-730 Tackles Tough Industrial Measurements

Data Acquisition > Voltage > DI-730 Imagine this measurement environment: Simultaneous measurements of 400+ source volts and 50 millivolt current shunts that are hundreds of volts off-ground. Now imagine trying to make this measurement against the background noise of SCRs chopping the motor supply at a 10 kHz rate. Traditional PC-based instrumentation vaporizes in this Read More

Casting off with WinDaq Software and the DI-730

Data Acquisition > Voltage > DI-730 Sport fishermen would recognize the product immediately. Though this one was rigged to a metal tub filled with water, most fishermen are used to seeing the product attached to the bow of a bass boat where it allows the skipper to easily and quietly maneuver the boat for a Read More

A Closer Look At The WinDaq Derivative Algorithm

Data Acquisition > Software > WinDaq The derivative is a mathematical tool used to obtain the rate of change from any given function. When the function to be differentiated is expressed as an equation, we would apply the appropriate derivative formula to attain the rate of change in a similar equation format. When the function Read More

DI-730 Data Acquisition System Aids Moon Roof Design and Qualification

Data Acquisition > Voltage > DI-730 It was a good, long run, but the strip chart recorder our customer had used for years was finally being replaced with a state-of-the-art PC-based data acquisition system. The recorder had become unreliable, and the paper records were tedious to analyze, and difficult to archive. The only problem was Read More
