Overview
The MK603 is a column load cell with a broad capacity range and strong overload resistance for large-tonnage weighing. Its rugged compression design holds stable, accurate output in harsh industrial duty, and high overload tolerance protects the sensor under shock and side loading on heavy structures.
Key Features
- Wide capacity range, strong overload resistance
- Stable output for large-tonnage weighing
- Rugged build for harsh industrial sites
- High accuracy (0.05~0.1%F.S) for precise measurement
- Alloy steel elastic element for durability and corrosion resistance
- Sealed to IP67 for reliable operation in harsh environments
Applications
Used for heavy-duty measurement on electronic truck and rail scales, storage and tank scales, and in pharmaceutical, chemical, coal, and metallurgical plants.
