Performance Considerations
The UTS is an angle sensor that uses an accelerometer to calculate changes in orientation. There are a few
factors that may influence the operation.
Vibrations
Due to the use of high-resolution accelerometers, vibrations can cause interference in certain applications. Once
the device is installed, it is recommended to operate all functions that may cause sudden vibrations/shock
across the vehicle to ensure regular operation is not interrupted. These instances will be picked up by the UTS as
angular changes and could have an adverse effect on regular operation depending on the application.
If it is determined that there is interference due to vibration, here are some solutions to investigate:
•
Ensure consistency with mounting recommendations outlined in this document is maintained
•
Increase programable filtering
•
Reduce the output resolution
•
Add vibration isolation (rubber dampeners)
•
Increase thickness of mounting surface
•
Reduce the vibrations from the source
•
Relocate the sensor to an area of lower vibration
•
Avoid installing the UTS in areas that are susceptible to large sonic vibrations
Operation at Extreme Linear Limits
It is recommended to avoid using extreme linear limits for critical angular measurements. Consider setting up an
operated range that is enclosed by a diagnostic zone at the limits of angular range. It is common practice to
allow 5-10% of the full range for these zones.
Signed Integers
The UTS broadcasts tilt angles using signed 16-bit integers.
Using multiple sensors on the same CAN bus system
Each UTS will need to have a unique source address.
