Port stacker-reclaimers operate in dust, vibration, and hazardous zones, so displacement feedback must be reliable and safe. The intrinsically safe explosion-proof LVDT displacement sensor, model IS-LVDT-50S, is designed for boom, hoist, and slewing position monitoring. Its stainless-steel housing, IP67 protection, and Ex ia IIC T4 Ga / Ex d IIC T6 Gb options suit harsh port environments.

Key specifications: measuring range 0–50 mm (custom 10–300 mm); linearity ≤±0.25% FS; repeatability ≤0.01 mm; resolution ≤1 µm; output 4–20 mA, 0–10 V, or RS485; supply 24 VDC; operating temperature -40°C to +85°C; pressure up to 35 MPa optional; vibration 20 g; isolation 1000 VDC. Intrinsically safe circuits require an approved barrier or isolator.

Model code: IS-LVDT-50S means intrinsically safe, LVDT, 50 mm range, stainless-steel body. Features include non-contact LVDT sensing, rugged construction, EMI shielding, pressure-resistant options, and easy calibration. Typical use covers stacker-reclaimer boom angle, bucket-wheel position, and hydraulic cylinder stroke. The sensor supports long cable runs when paired with a suitable isolator, helping maintain signal stability in electromagnetic noise. Installation should follow hazardous-area codes, use shielded twisted-pair cable, and ensure reliable grounding. Regular zero and span checks are recommended. Optional accessories include mounting clamps, waterproof connectors, and extension cables. Each unit is supplied with a calibration certificate and wiring diagram. This model improves positioning accuracy, reduces downtime, and supports safe continuous bulk material handling.
