A recent fix to our existing accelerometer has made it possible to measure impacts of up to 25g.
This impact will be displayed as “Impact” under the Fleet app --> Asset Home --> Insights in Trackunit Manager.
How is Impact calculated?
All Trackunit Raw devices (TU500 and above) include an accelerometer that measures acceleration in the X-, Y-, and Z-axis of up to 16g. The “Impact” displayed is the highest measured impact during the machine's capturing period.
The capturing period is as follows:
Machine condition | Capturing period |
Moving more than 8km/h (regardless if it’s turned on or off) | 2 minutes |
Operating while standing still | 15 minutes |
Non-operating and standing still | 60 minutes |
The Impact is calculated as follows:
sqrt(X^2 + Y^2 + Z^2) |
Note: Position of the Raw device can have effect on the Impact displayed.
For example, there is a damping effect if the device is tied to wires or hoses compared to if it is bolted to the chassis.
If the device is mounted close to the engine, engine vibrations can effect the data reading. Therefore it is recommended to mount the Raw device to a rigid part of the machine far enough away from the engine that engine vibrations will not influence the data reading.
How do I use Impact?
First of all, make sure your Raw device is the model TU500 or above.
When verified, reach out to Customer Support to get the latest firmware update on your fleet and activate Impact detection.
Log into Trackunit Manager
Go to the Fleet app and click on the machine you are interested in
Select Insights from Asset Home
Click Impact in Insights Overview
Select the date range you are interested in
You can now see and document high impact events for a specified period.
💡 Tip: If you want to see the approximate location for where the impact happened, you can find that data under the Movement tab. Read more about how to uncover the location of a machine here
You can also generate an Operations Report for the dates of the high impact event to see who the operator was. Read more about how to create an Operations Report here
