Port stacker-reclaimers handle bulk material in harsh, often hazardous port environments. Reliable position feedback is essential for boom, mast, bucket, travel, and chute control. The intrinsically safe explosion-proof magnetostrictive displacement sensor model MDS-EX-IS-PSR is designed for these duties. It combines a magnetostrictive waveguide, a stainless-steel pressure tube, and a non-contact position magnet. The housing is sealed for dust, moisture, salt spray, and vibration. Typical outputs are 4-20 mA, 0-10 V, RS485 Modbus, or SSI, with an isolated signal circuit.

Specifications: stroke 50-5000 mm; repeatability +/-0.01% FS; nonlinearity <=0.05% FS; resolution 0.01 mm; supply 24 VDC (18-36 VDC); current <=80 mA; protection IP67/IP68; explosion rating Ex ia IIC T4 Ga; ambient -40 to +85 deg C; cable length up to 100 m; process connection M18x1.5 or custom flange.

Installation uses a shielded cable, equipotential bonding, surge protection, and a stable magnet path. For selection, confirm hazardous area class, stroke, mounting space, output, cable route, and maintenance access. Factory calibration and periodic inspection support long-term accuracy in automated port operations. The model code MDS-EX-IS-PSR-xxxx indicates stroke, output, cable, and mounting options. Each unit is factory tested for insulation, zero point, full-scale output, and pressure tightness. Ordering data should state the hazardous area certificate, stroke in millimeters, connector type, and spare magnet.
