Measurex QSSB ML4 Assembly 053567 Rev A

The Measurex QSSB ML4 Assembly (part number 053567, Revision A) is a specialized circuit board designed for use in Measurex industrial measurement and control systems, particularly in the paper and pulp industry. This assembly is part of the Quad Sensor Scanner Board (QSSB) series, which integrates with scanning systems to measure properties like basis weight, moisture, and caliper in real-time during manufacturing processes. Key features include multiple integrated circuits for signal processing, edge connectors for modular integration, and robust design for harsh industrial environments. Benefits include high reliability in continuous operation, precise data acquisition for quality control, and compatibility with legacy Measurex/Honeywell systems, reducing downtime in upgrades. Drawbacks may involve obsolescence, as Measurex was acquired by Honeywell in 1997, leading to limited new parts availability and potential compatibility issues with modern digital systems. Applications span paper mills, converting plants, and other process industries requiring non-contact scanning. Compared to similar products like modern Honeywell scanners, it offers cost-effective retrofitting for existing setups but lacks advanced digital interfaces. Condition analysis from images shows it as used, with minor wear but no visible damage, wrapped in anti-static material for protection. No parent/child assets are evident.
