Pressure Vessels to Infinity and Beyond

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.

Pressure Vessels to Infinity and Beyond

Well, maybe not quite that far. As noted in an earlier Put the Pressure on Us blog, a pressure vessel is a storage tank or vessel that has been designed to operate at pressures above 15 psig. The Office of Safety and Mission Assurance Division of National Aeronautics and Space Administration (NASA) reports that there are approximately 10,000 ground-based Pressure Vessels and Systems (PVS) across the agency.

However, there are out of this world applications, too. One example is the pressure vessel built for the crew compartment of the Orion spacecraft. In this pressure vessel, flight crews will live and operate the spacecraft on flights from the Earth to cislunar (within the Moon’s orbit) space and back. While the vacuum of space exists outside of the vessel, an earthlike 15 psia pressure must be monitored and controlled inside to support the crew.

In contrast, an unpressurized lunar rover is being pursued as part of NASA’s project to land the first woman and the next man on the Moon by 2024. In this case, the astronauts’ suit will regulate the pressure the aliens from earth will need to survive.
