IN the student days of their career the majority of electrical engineers are strongly attracted towards the design and manufacture of large machines. To design a 10,000-h.p. dynamo is found to be ...

People breathing contaminated air over the course of years are at greater risk of developing numerous diseases. This is thought to be due to highly reactive components in particulate matter, which ...

When EDN published its first issue in 1956, electrical measuring instruments looked a little different than they do today. Howard Skolnik, a former colleague and key analog mentor from my Burr-Brown ...

Metrology is the science of precise measurement. It ensures accuracy and consistency across scientific, industrial, and engineering fields. Calibration is the process of aligning measurement ...

MR. ASPINALL PARR has aimed at giving a description of all the leading electrical measuring instruments on the market, and he has carried out this object with a painstaking thoroughness worthy of a ...

ISA recently published the third edition of Calibration Handbook of Measuring Instruments by Alessandro Brunelli. In this Q&A feature, Brunelli highlights the focus, importance, and differentiating ...

The demand to increase energy efficiency in electrical products is driving the development of more accurate measurement instruments. Modern instruments now can quantify incremental gains made as ...

Measurement of signals close to the your measuring instrument’s noise floor is always difficult. For many years the best Op Amps have had input noise floors of right around 1 nV/√Hz. This makes any ...

Despite highly specialized methods that can simultaneously produce a range of materials on a single sample and then measure them automatically, every minute counts when analyzing them: because days or ...

The electronic gauge is designed for measuring wheel rolling circle diameter with high precision. Measurements are made directly on rolling stock without wheelset roll-out. This is performed according ...
