BISOPE series 87- Trend and Time Waveform------------------------

The three major graphs of vibration analysis can be explained as time waveform, frequency spectrum, and trend graph.

However, there are cases where trend graphs and time waveform graphs are confused.

Generally, the graph that can be checked most often on the monitoring screen, especially in the control room, is the trend graph. Let's compare this with the time waveform graph to find out what the difference is.

 

 

Trend and Time Waveform

 

The difference between trend and time waveform is as follows.
