  • ShotMeter Particle Velocity Sensor
    peening nozzle. The signals from the two sensor are compared and the resulting phase shift is used to calculate velocity, with an accuracy within 1%. The particle velocity data is collected and displayed on a Windows based computer system and is extremely easy to use. In addition to particle
  • Velocity Factor in Cables
    . But the figure of merit here is. For a closed-cell foam dielectric, for example, the VOP may approach. the absolute phase angle of the cable at the specified frequency. 90%, meaning that a signal will travel at 90% of the speed of light. For. solid Teflon®, the VOP is typically about 70%. Wavelength, Phase
  • Phase Conjugate Sonar

  • Microwave Phase Difference
    fluid. Unlike the method that depends on monitoring the attenuation of a transmitted wave, measuring fluid density by observing a wave's phase difference is unaffected by flow velocity and/or is not affected by the contamination and/or bubbles.
  • Which Should I Use? Real & imaginary? Or magnitude & phase?
    to the basics. The FRF can show displacement, velocity and acceleration. They are all related but shifted in phase. Whether to watch imaginary part or real part depends what you are using and what are you expecting from the analysis. But if you forget the analysis itself and go back to mathematics
  • Smoothing Velocity Profiling (using IT and VT Commands) (.pdf)
    is set with the IT. command. Here is a table that describes the functionality based on the product line: Optima Series, DMC-1800, DMC-21xx, DMC-18x2, etc: Command. Effect. IT. smoothes AC, DC phase of motion due to JG, IP, PR, PA commands. VT. smoothes VA, VD phase of motion due to VP, CR, LI commands
  • Calculating Velocity Or Displacement From Acceleration Time Histories
    component important but the phase is also crucial because it can have a significant effect on the gross shape of the integrated output. An inspection of all the integrated output waveforms shown above reveals that instead of being bipolar like the inputs they are all predominantly positive
