Most engineers understand the concept of pressure. It’s a force, often measured in pounds, on a specific area. It is commonly listed in pounds per square inch (psi). But there are a variety of ...

There are essentially four different types of pressure measurement transmitters. Absolute pressure transmitters measure against a vacuum, meaning that if no pressure is applied, the reading would ...

The metrology revolution is gathering pace. Hot on the heels of an overhaul of the most fundamental ‘base’ units of measure in the International System of Units (SI) last month, some metrologists are ...

Highly accurate pressure sensors with long-term stability are necessary for fuel efficiency and reduction of harmful emissions. Increasingly demanding requirements of piezoresistive sensors include ...

There is a close relationship between science and discovery and measurement; indeed, many of the base units we use today are named after the very scientists responsible for how we understand the ...

If scientists had sacred objects, this would be one of them: a single, closely guarded 137-year-old cylinder of metal, housed in a vault outside of Paris. It is a prototype that precisely defines a ...
