Dynamic Pressure Measurements and Calibration
(PRE 501)
Overview for management and participants
- Need for pressure measurements (dynamic vs. static) and calibration
- Approximate scheduling so managers can audit special topics
Quiz for evaluation of attendee prior knowledge
Static pressure measurements
- Introduction; terminology
- Sensors
- Readouts
- Control
Classical sinusoidally varying pressure never observed in service, but a useful concept
- Introduction: terminology
- Sinusoidal pressure measurements: units, sensors, readouts, errors
- Senses acceleration as well as pressure
- Temperature effects
- Distance to sensor
- Calibration of sensors and systems; traceability to NIST
Most machinery pressures are complex; introduction to spectrum analysis
Interpretation of pressure measurement standards
Introduction to random pressure variations
- Sources cavitation
- No possible equivalence to sinusoidal pressure variations
- Terminology and definitions
- Spectral density measurement and analysis - the frequency domain
- Probability density - the time domain
Pressure transients (gunfire)
