VTR Series LVDT Spring Loaded Linear Position Sensor

The VTR Series LVDT Displacement Sensor is a high-precision linear measurement solution for industrial and research applications. Based on the Linear Variable Differential Transformer (LVDT) principle, it is designed to measure elongation, vibration, thickness, and expansion with outstanding accuracy and stability. Widely used in aerospace, machinery, construction, textiles, railways, mining, metallurgy, plastics, chemicals, and academic research, it ensures reliable performance even in demanding environments. The VTR Series adopts a DC single power supply (9–28V) design, with electronics sealed inside a 304 stainless steel housing. It provides standard output signals of 0–5V, 0–10V, or 4–20mA, making it directly compatible with PLCs and computer systems.
