Temperature Data Acquisition (DAQ) Systems (DAS), Recorders and Related I/O Modules

Data aquisition systems (DAQ or DAS) options have exploded as a result of the growth in Personal Computer (PC) hardware. Many companies make data acquisition (DAQ) cards to plug into desktop or ruggedized industrial models of PCs. Still others offer systems built out of component subassemblies including many PC components, such as single board PCs. The latest innovations involve high speed Universal Serial Bus or USB connectivity as indicated in the banner above. (Don't engineers love acronyms? We've got a link on MeasurementDevices.com, a related - it's in our "family"- website that covers some 5000+ acronyms and tech terms used in instrumentation and process control.)

More & more suppliers gear up for the longer run by imbedding microprocessors, custom programming and displays into proprietary packaged devices that are hybrids. They supply DAS/DAQ functions with one or more channels, display either temperature values or trends for one or more channels and often provide an interface and/or a storage means for sending collected data back to a another computer for later study and analyses.

There's lots of business and tremendous competetion.

Did we mention software? There are many kinds, many prices and many options. Some come packaged with the hardware at no additional charge.

We've just scratched the surface with this page and will fill it up in due order. At present most of the major suppliers are represented below.
