DATAQ Instruments Application Notes and News
Save a Segment of Data as a Second, Smaller File
Data Acquisition > Software > WinDaq The WinDaq Waveform Browser allows you to select a segment of data, and save it as a second, smaller file. Suppose you have a very large data file, recorded over several days, or even weeks. Now suppose that that file contains a significant event that transpired in a matter of Read More
Data Logger vs. Data Acquisition
Data Acquisition or Data Logger If you need to digitize an analog signal, record it, and provide a method to analyze it, do you need a data logger or a data acquisition system? It has become increasing clear that the answer is ‘Yes’ to both products. What I mean is that the traditional definitions of Read More
How To Measure Current
Data Acquisition > 4-20mA Current Loop …current is always measured indirectly from an external sensor that produces a voltage output that is proportional to current. Since the only difference between a voltage and current measurement is the scaling that you apply to the result, voltage measuring instruments are almost always used to measure current. Read More
WinDaq System Used in Bridge Monitoring
Data Acquisition > Ethernet > Distributed Synchronous The I-35W Mississippi River Bridge in Minneapolis, MN connects Downtown East to Marcy-Holmes. Following its catastrophic failure on August 1, 2007, a decision was made to rebuild the bridge with a state-of-the-art monitoring system. The contractor chose DATAQ Instruments hardware and software for the job due to our expertise Read More
FFT (Fast Fourier Transform) Waveform Analysis
Data Acquisition > Software > WinDaq To calculate an FFT (Fast Fourier Transform), just listen. The human ear automatically and involuntarily performs a calculation that takes the intellect years of mathematical education to accomplish. The ear formulates a transform by converting sound—the waves of pressure traveling over time and through the atmosphere—into a spectrum, a Read More
Three Easy Steps for Stand-alone Data Logging Using a DI-71x Data Logger
Data Logger > Stand Alone Configure Connect a Data Logger to the USB or Ethernet port of your PC and run the provided set up software. Configure the data logger for your specific requirements in the following ways: Enable or disable specific analog channels in any order. For enabled channels define input configuration (single-ended or Read More
Data Acquisition Tips and Techniques
Data Acquisition > Mixed Measurements A Guide To Data Acquisition Signal Input Configuration Does a thermocouple signal require isolation? Should the output of a strain gage amplifier be connected as a single-ended or differential input? Is a differential input always a better choice than a single-ended configuration? These fundamental instrumentation questions may not be easy Read More
Synchronized and Distributed Data Acquisition Using DI-720/DI-730 Instruments in Hot Strip Steel Mills
Data Acquisition > Ethernet > Distributed Synchronous Background The need to acquire data in a distributed and synchronized manner is required in a variety of applications. Consider a hot strip mill that creates a long steel coil starting from a slab of steel. The process consists of: A pre-heat procedure that heats the initially cold Read More
Intelligent Oversampling Methods Add Measurement Flexibility
Data Acquisition > Software > WinDaq Editor’s note: Watch our YouTube videos for in-depth Intelligent Oversampling demonstrations. DATAQ Instruments has established a tradition of developing data acquisition boards that provide programmable intelligent oversampling on a per channel basis. This instrumentation approach is little-known and is only supported by DATAQ Instruments products. The programmable intelligent oversampling Read More
