LVDT Transducers (Linear Variable Differential Transformer)
LVDT Transducers (Linear Variable Differential Transformer) Precision Linear Position Sensing Solutions
Definition & Overview
LVDT Transducers (Linear Variable Differential Transformers) are high-accuracy electromechanical sensors designed to measure linear displacement or position with exceptional precision. As a specialized subcategory under Sensors & Transducers, LVDTs convert physical linear motion into proportional electrical signals using electromagnetic induction. Renowned for their robustness, infinite resolution, and frictionless operation, they are widely adopted in aerospace, industrial automation, automotive testing, and metrology applications.
Types of LVDT Transducers
1. DC-LVDTs: Integrated signal conditioning for DC voltage/current output, ideal for OEM systems.
2. AC-LVDTs: Require external carrier frequency excitation but offer higher temperature stability.
3. Miniature LVDTs: Compact designs for confined spaces (e.g., medical devices).
4. Sealed/High-Pressure LVDTs: Engineered for harsh environments (hydraulics, oil & gas).
5. Spring-Extended LVDTs: Self-positioning variants for dynamic measurements.
Purchasing Considerations
- Measurement Range: Select core stroke length (e.g., 1mm to 500mm) aligned with your application.
- Output Signal: Choose AC (raw) or DC (amplified) based on system compatibility.
- Environmental Ratings: Prioritize IP67/IP68 or MIL-STD compliance for extreme conditions.
- Accuracy & Linearity: Critical for metrology; opt for < 0.1% nonlinearity models.
- Mounting & Integration: Verify mechanical compatibility (threaded, flanged, or rod-end styles).
LVDT transducers deliver unmatched reliability for mission-critical linear positioning tasks. Partner with trusted suppliers offering NIST-traceable calibration and customization support.
