Installing a corrosion-resistant magnetostrictive displacement sensor on a bridge crane requires stable alignment, protection from weld heat, and isolation from moisture and galvanic corrosion. First, confirm the measuring axis and stroke. Mount the sensor body on a rigid, non-flexing structure such as the end carriage or main girder bracket, not on vibrating panels. Use a 304/316 stainless bracket with drainage holes and a protective shield. Keep the sensor parallel to crane travel and within the manufacturer's lateral tolerance. Weld brackets before sensor installation; never weld near the sensor, because heat can damage electronics and magnets. If field welding is unavoidable, remove the sensor, use heat barriers, and recheck alignment.

Attach the position magnet to the moving trolley or bridge component with a stainless clamp. Maintain the specified gap and avoid eccentric load. Use anti-seize on stainless fasteners to prevent galling, and install insulating washers where dissimilar metals contact to reduce galvanic corrosion. Route the cable in a protected conduit with a drip loop; seal connectors with chemical-resistant tape or heat-shrink. Ground the shield at the control cabinet only, following EMC practice. After installation, cycle the crane slowly through full travel, verify stable readings, set zero and span, and tighten locknuts. Periodically inspect seals, drain holes, and bracket corrosion. This method ensures accurate displacement feedback and long service life in harsh bridge crane environments.
