Overview
The MK301 is a bellows load cell with a welded, sealed stainless-steel bellows that resists dust and moisture. It measures both tension and compression and offers strong overload, fatigue and eccentric-load resistance.
Key Features
- High accuracy (≤±0.02%F.S) for precise measurement
- Stainless steel elastic element for durability and corrosion resistance
- Sealed to IP68 for reliable operation in harsh environments
- Standard output 2.0±0.25%mV/V, compatible with common indicators
- Compact design for straightforward integration
Applications
Suited to platform, packaging, belt-conveyor and tank scales.
