LVDT Sensor
Measures precise linear displacement with high accuracy and long-term reliability.
What Does an LVDT Sensor Measure?
An LVDT (Linear Variable Differential Transformer) measures linear displacement of a movable core relative to a fixed reference. It provides highly accurate, repeatable position feedback without physical contact, making it ideal for harsh industrial environments.
Signal Output
- Analog: AC output proportional to displacement
- Analog: 4–20 mA or 0–10 V (with signal conditioning)
- High resolution linear position signal
- Bidirectional displacement measurement
What Does the Signal Mean?
| LVDT Behaviour | Industrial Meaning |
|---|---|
| Stable linear output | Accurate position and smooth mechanical movement |
| Non-linear response | Mechanical misalignment or core damage |
| Output drift | Temperature variation or signal conditioning issue |
| No signal | Sensor excitation or wiring failure |
