Waterproof LVDT displacement sensors are used in wet, dusty, and outdoor environments where standard sensors may fail. Their price depends on stroke length, accuracy, output signal, housing material, cable sealing, and IP rating. A basic IP67 model with a short stroke may cost about $120–$250. Mid-range IP68 units with longer strokes, stainless steel bodies, and 4–20 mA or Modbus outputs often range from $300–$600. High-accuracy, custom, or high-temperature waterproof LVDTs can exceed $800. Buyers should compare total cost, not only unit price. Calibration certificates, connectors, cable length, lead time, and after-sales support affect value. For OEM projects, volume orders usually lower unit prices. A stainless steel housing and robust cable gland improve durability in washdown, marine, and outdoor applications. The output type also matters: 0–5 V, 0–10 V, 4–20 mA, and digital options may have different prices. Longer measuring ranges and tighter linearity increase manufacturing difficulty and cost. To get an accurate quote, specify measuring range, output type, supply voltage, IP rating, operating temperature, thread size, and cable length. Ask for the test report, protection class, and warranty terms. When requesting samples, confirm the cable jacket material and connector type, because these details strongly influence long-term reliability and final price. A reliable supplier can recommend the right waterproof LVDT displacement sensor and help balance performance and budget.
