Selecting a high-temperature LVDT displacement sensor for a stacker-reclaimer requires balancing price with reliability. These sensors monitor boom, mast, travel, or bucket-wheel position in dusty, vibrating, and hot bulk material handling sites. A low-cost standard LVDT may fail early, so verify the actual radiant heat, ambient temperature, shock, and IP rating. Market prices often range from several hundred to over two thousand USD, depending on stroke length, temperature rating, housing material, cable, connector, output signal, and certification. High-temperature coils, special alloys, thermal isolation, and rugged sealing raise cost, but they protect accuracy and service life. For an accurate quotation, provide stroke, excitation voltage, output signal, operating temperature, mounting space, cable length, and required connectors. Compare suppliers on calibration, repeatability, lead time, warranty, and spare-part support. A slightly higher-priced sensor with proven stacker-reclaimer references can lower downtime and total ownership cost. Request test reports, drawings, and application evidence before ordering. Ask for the sensor's thermal compensation method, linearity, repeatability, and vibration resistance. Confirm the mounting thread, rod end, and cable exit match the machine. For spare parts, keep the model, stroke, and temperature class in your maintenance records. A technical datasheet helps buyers compare quotes and avoid hidden costs from adapters, extra cable, or expedited shipping.
