LOAD CELL ZEMIC ANALOG 30 MT
Zemic analog loadcells, like the HM9B dual shear beam series, are robust nickel-plated alloy steel sensors designed for truck scales, weighbridges, and heavy-duty platforms up to 50t. They deliver OIML R60 C3 accuracy with standard 2 mV/V output for analog weighing systems.
Key Specifications
Specs focus on high-capacity models (10-50t), comparable to Keli QS analog variants for industrial/dairy use.

Product Description
Dimensions (HM9B)
-
Height varies: 195mm (10t), up to 267mm (50t); cable 16-20m shielded
Wiring follows standard 4/6-wire codes (red E+, green S+, black E-, white S-), matching prior discussions
Zemic analog load cells use a standard 4-wire color code for reliable connections in parallel setups via junction boxes, matching industry norms like Keli analog models. Always confirm with the calibration certificate for your specific model (e.g., HM9B, L6P).
