Overview
Built around a resilient parallel-beam element, the MK738 load cell delivers high accuracy with strong rejection of off-centre and side forces, and holds up to continuous industrial duty. Its compact form simplifies retrofit into existing scale platforms, while measurement repeatability supports automated control loops.
Key Features
- High accuracy (–) for precise measurement
- Aluminum alloy elastic element for durability and corrosion resistance
- Sealed to IP65 for reliable operation in harsh environments
- Standard output 1.0±10%mV/V, compatible with common indicators
- Compact design for straightforward integration
Applications
Common in batching and dosing scales, quantitative packaging and checkweighing equipment, hopper and belt scales, and sortation lines.
