For best performance, the target rod used with an LVIT (Linear Variable Inductive Transducer) should be made from an electrically conductive material—preferably aluminum, brass, or 300-series stainless steel.
Why Target Rod Material Matters
LVIT sensors operate by detecting changes in inductance caused by the movement of a conductive target rod. The electrical conductivity of the rod’s surface plays a critical role in sensor performance.
Higher conductivity allows for easier and more precise detection of position changes, directly influencing accuracy, linearity, and sensitivity.
Recommended Materials (Rod or Tubing)
- 300 Series Stainless Steel
- Aluminum (6061 or similar grades)
- Brass
- Copper-plated materials
- Carbon or Alloy Steels (if conductive enough for the application)
Materials to Avoid
- Plastics and Composites – These are non-conductive and incompatible with LVIT sensors.
- Low Surface Conductivity Materials – Can lead to weak or unstable sensor signals.
- Inconsistently Plated Materials – May cause signal degradation or inconsistencies.
Target Rod Best Practices
- Ensure the target rod has a uniform diameter along the sensing range.
- Avoid rods with corrosion, oxidation, or surface damage.
- Replace damaged or deformed rods, as they can compromise performance.
- If the target rod is replaced or modified, factory recalibration of the sensor may be necessary.
Summary
For optimal results with HGSI LVIT sensors, always use recommended conductive materials with clean, uniform surfaces. This ensures accurate, reliable, and interference-free operation in your application.
