Overview
The MK303 is a bellows load cell using a welded stainless-steel bellows seal to protect the sensing element in plant service. It accepts both tension and compression loading and resists overload, fatigue and off-centre forces, so output stays repeatable through long cycles of duty.
Key Features
- Welded stainless-steel bellows seal
- Handles tension and compression alike
- Resists overload, fatigue and off-centre loads
- High accuracy (≤±0.02%F.S) for precise measurement
- Alloy steel elastic element for durability and corrosion resistance
- Sealed to IP67 for reliable operation in harsh environments
Applications
Platform scales, packaging scales, belt-conveyor scales and tank or hopper scales in industrial weighing.
