How do you measure the causes of a noise or vibration with respect to several sources? Which source is causing what part of the response?
For example, how does the noise inside the cabin of a vehicle relate to the engine noise or wheel hub noise and vibration? Continue reading What is Source Contribution Analysis (or SCA)?
ODS = Motion of structure vibrating naturally (for example bridge vibration) or when excited by an unknown force (for example generator vibration). Prosig’s Structural Animation software performs ODS analysis.
OMA = Modal Analysis
Prosig’s Modal Analysis software performs OMA. Continue reading What is the difference between Operating Deflection Shapes (ODS) and Operational Modal Analysis (OMA)?
The P8000 Auto Range and the Auto Gain Range functions are often confused by users. They are not the same, but they are related. Continue reading Understanding Auto Range & Auto Gain Range
The latest version of Prosig’s DATS software was released today and is available to download from the Prosig Support web pages. Read on to find out about some the new features… Continue reading New Version Of DATS Out Now – V7.0.22 Released
This is complete version of the video illustrating my recent article How To Measure Noise & Vibration In Rotating Machines. This video was previously published on the blog in 3 parts.
The video will be best enjoyed by selecting the 720p option and selecting full screen mode.
This is the final part of our four part tutorial. This adds a report to the worksheet we developed in part 3.
Today we have the third of our four part tutorial. Here we show how to quickly build a worksheet to analyze the data we captured in parts one and two.
Part four will follow on Monday
Part two of the four tutorials showing a simple setup to capture, analyze and produce a report using Prosig’s DATS software and P8000 hardware. This part deals with setting up realtime displays in the data capture.
Part three to follow soon
The first part of a series of four tutorials showing a simple setup to capture, analyze and produce a report using Prosig’s DATS software and P8000 hardware.
Part 2 coming soon…
This note describes the importance and setup of a keyphasor or tachometer signal for PROTOR Remote Monitoring Data Acquisition System (RMDAS) units. RMDAS units are provided with manual tachometer conditioning control. The note describes the control functions and there effect on the conditioned tachometer signal, it also describes the relationship between phase measurement and keyphasor triggering.
