Overview
Engineered for heavy platform duty, the MK502 cantilever beam load cell combines a low mounting height with high combined accuracy and a self-stabilising structure for consistent long-term readings. Its nickel-plated alloy-steel body is sealed to IP67 against the weather and grime of yard service.
Key Features
- High accuracy (C2 C3) for precise measurement
- Alloy steel elastic element for durability and corrosion resistance
- Sealed to IP67 / IP68 for reliable operation in harsh environments
- Standard output 2.0 ± 0.2%mV/V (<30kN)3.0 ± 0.2%mV/V (≥30kN), compatible with common indicators
- Compact design for straightforward integration
Applications
Applied to floor scales, truck weighbridges, rail scales and general batching and dosing weight control.
