Vibration Sensor Approaches for the Monitoring of Sand ...

The real-time monitoring of sand production has always been an important issue during the process of oil production in offshore field. This paper illustrates a new alternative vibration sensor approach to monitor the sand production. A special broadband sensor was selected. Then the time-frequency analysis, characteristic sand frequency band filter method, and peak searching-denoising method ...

POWER SPECTRAL DENSITY UNITS: [ Revision B By Tom Irvine

Random vibration, however, is very complicated. Random vibration has no simple relationship between its peak and RMS values. The peak value of a stationary random time history is typically 3 or 4 times the RMS value. A power spectral density can be calculated for any type of vibration signal, but it is particularly appropriate for random ...

Experimental evaluation of sand particle identification in ...

For sand–water–gas bubbly flow, Sensor-1 could measure the change of the vibration RMS level caused by sand injection (sand concentration of 0.2 wt.%), while, it was less sensitive than Sensor-3. For sand–oil–water–gas bubbly flow, only Sensor-3 could identify the sand vibration variations for different sand concentrations and sizes.

Shock and vibration data logger - Wikipedia

A shock data logger or vibration data logger is a measurement instrument that is capable of autonomously recording shocks or vibrations over a defined period of time. Digital data is usually in the form of acceleration and time. The shock and vibration data can be retrieved (or transmitted), viewed and evaluated after it has been recorded.
