• First, the devices that measure fundamental variables of the SI unit system are the most widely used. They’re together, with a few extras per the Bureau International des Poids et Mesures, (The International Bureau of Weights and Measures or BIPM) model .
• Second, the main functional use of devices, seems a useful way to group specialized devices. So, they are, e.g. Electrical, Process, Testing, Scientific, etc.
• Third, there are always those that defy ready classification by any scheme. They’re probably new also, but called “Others” here. Quite often they will show up in one of the stories about measurement devices that I will feature on this blog.
• Finally, the missed items. They may be as yet undiscovered by me and your help is always appreciated. You can make suggestions using the free comment form (below).

Recognize, too, that despite this simple listing, many measurements variables can be found in multiple device type categories, e.g. time, speed, pulse rate, velocity, acceleration, count rate, interval, delay…

Try a search engine if you have a variable or sensor name. We like DuckDuckGo, but Bing has been getting better lately, and don’t forget Yahoo! (It’s actually been in the search business longer than the Big G!).

Your feedback is requested to help make this blog better, please.
