Overview
The MK721 parallel-beam load cell is engineered around accuracy, robustness and immunity to off-centre forces. Compact and stable in service, it acts as the core weighing element in plant equipment where repeatable results must feed automated control without frequent re-adjustment.
Key Features
- High accuracy (–) for precise measurement
- Aluminum alloy elastic element for durability and corrosion resistance
- Sealed to IP65 for reliable operation in harsh environments
- Standard output 2.0±0.5%mV/V, compatible with common indicators
- Compact design for straightforward integration
Applications
Ingredient batching, quantitative packaging, electronic belt and hopper scales, plus automated sortation systems.
