How much is an LVDT displacement sensor? There is no single price. A basic AC LVDT often costs $50-$200. A DC LVDT with built-in electronics usually costs $100-$500. High-precision, rugged, or custom units can cost $500-$2,000, while extreme-environment models may exceed $5,000.

Price depends on measuring range, accuracy, output, and construction. Longer stroke, lower nonlinearity, and higher repeatability increase cost. AC output needs an external signal conditioner. DC, 4-20 mA, 0-10 V, or digital outputs add electronics. Stainless steel housings, hermetic seals, IP67/IP68 ratings, and special connectors raise price. ATEX, aerospace, nuclear, or automotive approvals require testing and documentation. OEM quantities reduce unit price, but one prototype can be costly.

When comparing quotes, check total cost. Add signal conditioner, power supply, cables, mounting, calibration, shipping, and lead time. A cheap LVDT may fail under vibration, moisture, or temperature extremes. For critical machines, reliability matters more than the lowest price.

Common applications include aerospace, automotive testing, hydraulic valves, turbine clearance, factory automation, and civil engineering. For a lab, a basic AC LVDT may be enough. For heavy industry, choose a sealed DC LVDT with robust output.

To get an accurate price, specify stroke, accuracy, output, temperature range, IP rating, connector, and quantity. Ask suppliers for datasheets, calibration options, and warranty. In short, LVDT displacement sensors range from under $100 to over $5,000.
