Overview
The MK740 parallel-beam load cell combines accuracy with strong resistance to off-centre loading and the durability needed for continuous plant service. Its stable output and compact footprint make it a dependable sensing core for automated weighing installations that must also survive a busy production floor.
Key Features
- High accuracy (–) for precise measurement
- Aluminum alloy elastic element for durability and corrosion resistance
- Sealed to IP66 for reliable operation in harsh environments
- Standard output 2.0±5%mV/V, compatible with common indicators
- Compact design for straightforward integration
Applications
Fitted to industrial batching scales, quantitative packaging scales, belt-conveyor scales, hopper scales and automatic sortation systems.
