DATAQ Instruments Application Notes and News
A Closer Look At The Advanced CODAS Moving Average Algorithm
Data Acquisition > Software > WinDaq > Advanced CODAS Versatile moving average in Advanced CODAS algorithm filters waveform noise, extracts mean, and eliminates baseline drift. The moving average is a simple mathematical technique used primarily to eliminate aberrations and reveal the real trend in a collection of data points. You might be familiar with it 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
A Closer Look at Waveform Integration with Advanced CODAS
Data Acquisition > Software > WinDaq > Advanced CODAS Mathematics has relied on the integration function for centuries as an aid to understanding the interrelationships of physical measurements. For example, an integral (or area under the curve) function can be applied to achieve units transformation. A velocity equation may be integrated to derive an equation 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
The Fact, Folly and Mathematics of Analog to Digital Converter Resolution
Data Acquisition > Software > WinDaq Everyone agrees that higher resolution analog to digital converters (ADCs) are better, right? So why do so many end-users shell out bucks for one and then fail to exploit that advantage? What I mean is that we are too often shocked when we receive data files from customers with Read More
Variable Speed Drive Measurements using the DI-730 Data Acquisition System
Data Acquisition > Voltage > DI-730 Motors using variable speed drives are found at virtually all levels of production, from mining raw materials and processing them into finished goods, to transporting those to market. Examples include open pit mining machines, steel and steel rolling mills, aluminum rolling mills, paper mills, heavy duty cranes, heavy duty Read More
Frequency and True RMS Data Acquisition
Data Acquisition > Mixed Measurements Are you looking for a quick and easy way to calculate, display, and record frequency and/or True RMS data? Are you interested in saving money? DATAQ Instruments, Inc. has a solution for you. Beginning with the July, 2003 (version 2.85) release of WinDaq data acquisition software, it is possible to calculate, display, Read More
Synchronized and Distributed Data Acquisition Using DI-1000 Instruments in Hot Strip Steel Mills
Data Acquisition > Thermocouple > DI-1000TC Background The need for data acquisition 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 slab Read More
How To Determine 4-20 mA Loop Load
Data Acquisition > Current Additional Reading: 4-20 mA Shunt Resistor and Current Loop Data Acquisition Products Process current (4-20 mA) measurements are popular with DATAQ Instruments’ customers, and that often leads to some interesting application questions. One of the better ones relates to how many process current instruments can be connected to a single current Read More
