Overview
The MK302 bellows load cell uses a welded stainless-steel bellows seal to protect the sensing element while allowing measurement in both tension and compression. That construction gives firm resistance to overload, fatigue and off-centre loading, so the cell holds its calibration through repeated duty cycles.
Key Features
- Welded stainless-steel bellows seal
- Measures tension and compression
- Resists overload, fatigue and side loads
- 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
Applications
Suitable for platform scales, packaging scales, belt-conveyor scales and tank or vessel weighing in general industrial service.
