Measurement devices, measurement education & measuring
This is the fourth essay in a series expanding on an article I wrote for Sensors titled "A Twelve-Step Sensor Selection Checklist". (Note: It has been modified very slightly to make it more easily read in this format) In October (2007), I discussed the need to consider factors that influence measurement conditions. This month, I'll talk about other considerations and best practices for … [Read more...]
Here's a little change of pace from the relative "dryness" of measurement tips & practices. It's something I missed and has some interesting results from measurements made at a very long distance!

Aug 21, 2007 - By: G. Raymond Peacock, Temperatures.com Inc. - Sensors In my last essay, I began a series on the step-by-step process careful engineers often follow to select a suitable sensor for an application. In that essay, I explained how to establish measurement span, or range, requirements. This month, I'll look at accuracy and measurement uncertainty. Definitions While automation … [Read more...]
Originally published online on Jun 19, 2007 - Author: G. Raymond Peacock, Temperatures.com Inc. - Publication: "Sensors" I'm a measurement guy. I believe making competent, reliable measurement within acceptable error tolerances is at the root of efficient automation. This approach is known by various names, including statistical process control and Six Sigma. Both are prominent in … [Read more...]
Some may recall the article done a while back (actually there are three) on the Science teacher, Steve Dickie, from Dearborn Michigan, who is using some very clever Internet and other technology in teaching physics to High School students. He's not alone, many teachers are using the Web, but Steve seems very adept and progressive in the things he does. We need to encourage such efforts and … [Read more...]
The ISA (which used to be the acronym for the Instrument Society of America but now stands for the Instrumentation, Systems and Automation Society -shouldn't that be ISAS... whatever) publishes a monthly magazine for its members called InTech. I've been getting the paper version for more than 35 years and just the other day I received an email announcing a online Digital version of InTech. If … [Read more...]
