SUMMARY

To determine negative ambient pressure, utilizing a manometer is the most effective method. Alternative techniques such as laser beams and ultrasound can be explored for non-contact measurements, but they may not provide the accuracy required for precise pressure readings. The discussion emphasizes the importance of selecting the right tool based on the specific application, particularly for measuring pressure inside a confined space like a plastic see-through box.

PREREQUISITES
  • Understanding of manometer operation and types
  • Familiarity with laser measurement techniques
  • Knowledge of ultrasound technology for pressure measurement
  • Basic principles of fluid dynamics and pressure measurement
NEXT STEPS
  • Research the different types of manometers and their applications
  • Explore laser-based pressure measurement technologies
  • Investigate ultrasound methods for non-contact pressure sensing
  • Study the principles of negative pressure and its implications in various environments
USEFUL FOR

Engineers, physicists, and technicians involved in pressure measurement, as well as anyone interested in non-contact sensing technologies.

hello!

which methods are available to determine (negative) ambient pressure?

for example, I want to check the pressure inside a plastic see-through box

can I send a beam of laser, an ultrasound, or something else to determine it?

thanks!
