Explosion-proof LVDT displacement sensors are critical for monitoring gate, valve, and slide positions in mixing station silos. Because these areas can contain combustible dust or gas, the sensor must combine precise linear measurement with certified flameproof or intrinsically safe protection. Price varies with stroke length, accuracy, output signal, housing material, cable and connector type, and required certifications. A standard 0-100 mm unit may cost less than a 0-500 mm custom model, while ATEX/IECEx approval, stainless steel housing, IP67/IP68 sealing, and high-temperature versions add cost. Buyers should compare total lifecycle value, not only the unit price: installation, calibration, spare parts, lead time, and after-sales support all affect project budgets. For mixing station silos, select a sensor with robust EMI shielding, stable 4-20 mA or RS485 output, and a mounting design that resists vibration and dust. Confirm the measuring range, operating temperature, pressure, and connection thread before requesting a quote. Ask suppliers for drawings, calibration reports, material certificates, and explosion-proof certificates. Small orders often carry higher unit prices, while batch orders can reduce costs. Typical market quotes range widely because protection class, stroke, and signal output change the design. Fast delivery and reliable technical support also influence the final quotation.
