The Value of Pressure

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

The Value of Pressure

Pressure makes diamonds” ― George S. Patton Jr.

While Patton was referring to the stress that can transition those who survive it into better individuals, carbon subjected to intense pressure and heat for millions of years turns into diamonds. In fact, the right combination of heat, pressure and time can crystallize many other minerals.

For natural diamonds, the pressure results from their formation at depths of 140 to 190 kilometers (87 to 118 mi) in the Earth’s mantle – below the Earth’s crust.

The Hope Diamond

When Tracy Hall achieved the first commercially successful synthesis of diamond in 1954, a more specific pressure value was identified. Hall used a “belt” press, which was capable of producing pressures above 10 GPa (1,500,000 psi) and temperatures above 2,000 °C (3,630 °F).

Pressure is essential in creating diamonds and other precious gems, but its greatest value is in healthcare. Without your health, everything else means nothing. Blood pressure, respiratory flow, interocular pressure and other pressure measurements indicate good health or a health problem. Cost-effective microelectromechanical (MEMS) pressure sensors provide value by confirming good health or helping diagnose problems to correct them and restore good health.
