DAQs work within computer systems. However, in order to make data acquisition work you must transmit and receive signals in order to process the information. There are a wide variety of interfaces used to connect data acquisition hardware to computers such as PCI bus, Ethernet and USB protocols. In addition to interfaces connecting DAQ systems […]

Portable Metrology Pushes Race Teams to Creative Engineering
by Cathy Hayat, Hexagon Metrology, Inc. Metrology became an essential part of the build process once NASCAR brought tighter tolerances into play. At the competitive edge of every professional sport, the margins of victory are often tiny differences in energy, efficiency, skill and physical configuration. Over time, this gives rise to elaborate regulations governing competitors’ behavior, […]
DAQ Series: Podcast: miniSystems for Engineering Excellence
In this DAQ Series, we discuss how DAQs are scaled down for educational purposes. National Instruments is dedicated to teaching engineering fundamentals beyond theory and mathematical applications. Its target is to teach students engineering concepts as a whole. The idea of teaching students hands-on, visual applications came from the suggestions of professors and teachers at […]
DAQ Series: Methodology associated with data acquisition
In the previous DAQ series, What is a Data Acquisition (DAQ), and How DAQs Work at a High Level, terminology that is analogous with DAQs was mentioned. To delve further, this series will discuss the some of the methodology associated with data acquisition. Transducers, Sensors, Actuators: As we know, data acquisition begins with a physical […]
DAQ Series: How DAQs work at a high level
As Daniel Carnes (Facebook reader) said, “As more and more data acquisition systems make their way into our lives it is good to know how they work at least at a high level.” Taking a cue from Mr. Carnes, engineers are no longer stereotyped as the person wearing the white coat in a lab. We […]
OMEGA Introduces High Temperature Pressure Data Logger
The OM-CP-PR140 is a pressure data logger designed for use in autoclave validation and mapping.This rugged device can withstand temperatures up to 140°C (284°F) and is completely submersible (IP68). The OM-CP-PR140 is built with a precision stainless steel pressure gauge. The device has an accuracy of ±0.03 Bar (±0.435 psi), which can be achieved over […]

This company offers a comprehensive technical support service to their customer base, and part of this service includes technical advice and assistance to maximize their customers’ production efficiency. CAS DataLoggers provided the […]
DAQ Series: What is a Data Acquisition System (DAQ)?
Data acquisition systems (DAQ) are getting a lot of engineers’ attention lately. Pondering minds would like to know what is a DAQ? To clarify, it is simpler to explain what a DAQ “does” than to answer, “What it is”. The DAQ was invented circa 1964, with the purpose of doing something with software. Initially, DAQ’s […]
Agilent Technologies and SiSoft Introduce Pre-Standard IBIS-AMI Modeling Guide
Agilent Technologies Inc. and Signal Integrity Software, Inc. announced guidelines that enable system designers to use advanced jitter and broadband analog capabilities when modeling high-speed serial devices. The modeling guidelines are based on proposed enhancements to the IBIS Algorithmic Modeling Interface (116-118 and 123.5), which are expected to be included in the specification’s next version. Both SiSoft […]
