Understanding the FitMachine Measured Data Chart

This chart shows you readings of vibration and temperature during a set time window.

How can it help you?

Use this chart to look for trends in vibration or temperature to discover how your equipment is changing. It is most powerful when used in conjunction with the AI Output Chart

Some trends to look out for include:

  • An upward trend especially if it is accelerating - this is likely related to deteriorating equipment condition
  • Recurring changes - which could be certain parameters affecting the way the equipment operates or could be related to process changes

How does it work?

As with all our charts, you can click on any of the datasets to toggle them off/on. Changing the selected dates will update all of the charts on the page.

On the left-hand axis is the temperature which is represented by the black line on the chart. On the right-hand axis is the RMS (vibration) which is represented by the blue line on the chart. For each sample that the FitMachine sensor sends there will be a data point for temperature and RMS.

Also shown on the graph is the running cut-off in red. This is how the system determines whether the equipment is running or not. If the RMS is about the running cut-off then the system considers the equipment as running.

Measured Data + ISO

The cog in the top right corner allows you to access several features that make the system work for you. These include:

  • Adjusting the running cut-off: This feature allows you to adjust the level of vibration which determines if the equipment is running or not. Primarily used when nearby equipment increases the base level of vibration of the monitored equipment.
  • Adjusting the learning start date: This feature allows you to restart the learning of your FitMachine sensor if needed. 
  • Measured Data Alarms: This feature allows you to set thresholds where your equipment is vibrating or running at too high or too low levels, to assist with maintenance 

Here you'll also notice a reading of your equipment's RMS and class with a coloured dot, and an ISO Table (example below). The table provides you with a representation of the vibration of your equipment against the ISO Vibration Standards chart relative to the vibration experienced by the asset and its class. Based on where your asset sits (represented by an equipment icon on the table), the colour of the dot will change. 

ISO Table

As an example, you can use this table as a guideline for setting Measured Data Alarms or to understand if the asset's learned 'normal' data was in a healthy state. This is significant as the health of your equipment may change and shift into the red zone on the ISO Table, but our AI may not consider this a significant change if the learned 'normal' state of the asset was already in the yellow. 

If the ISO Class hasn't been correctly entered for the equipment, or if the RMS is below the lowest RMS value on the table, the dot will be grey, the caption will be "ISO Class Unknown", and no icon will be displayed on the ISO Table. 

What else should I look at?
