An AC LVDT (Linear Variable Differential Transformer) is designed to provide accurate and reliable displacement measurements within a defined travel range. Operating the sensor beyond this specified range can lead to performance issues and compromised data accuracy.
What Happens If You Exceed the LVDT’s Travel Range?
Exceeding the specified linear range of an AC LVDT results in loss of linearity, meaning the output signal no longer accurately reflects the actual movement. As you move further beyond the range, this non-linearity becomes more pronounced and can ultimately cause saturation of the output signal. This leads to inaccurate, unstable, or misleading measurements.
How to Avoid Measurement Issues
To ensure reliable operation:
- Select an LVDT with a travel range that meets or exceeds your application’s maximum displacement.
- Incorporate limit detection features in your system to alert users if the sensor travels beyond its intended range.
Choosing the right sensor and planning for maximum motion will help maintain consistent performance and extend the life of your measurement system.
