Overview
The MK731 is a parallel-beam load cell engineered for stable, high-accuracy weighing where side and off-centre forces are a concern. Rugged and compact, it holds its readings across long production runs and integrates easily into scale platforms.
Key Features
- High accuracy (–) for precise measurement
- Aluminum alloy elastic element for durability and corrosion resistance
- Sealed to IP66 for reliable operation in harsh environments
- Standard output 2.0±0.5%mV/V, compatible with common indicators
- Compact design for straightforward integration
Applications
Used in industrial batching and quantitative packaging scales, belt and hopper weighing, and automated sortation systems.
