How to Choose an Industrial Weighing Module

Choose an industrial weighing module by sizing five things: the capacity per support point (total load including the vessel, distributed across the points, with dynamic margin), the overload ratings (safe and ultimate), the accuracy terms you actually need (non-linearity, repeatability, creep — not a single "accuracy" number), the mounting mechanics (support-point count, level, thermal-expansion freedom, side-load control), and the signal chain (mV/V output into a weighing indicator or transmitter, then PLC). KJT Sensors' KJT-MKWY002 spoke-type weighing module is a documented example covering 1–60 t capacities.

Key Takeaways

• Capacity is per point, with margin. Divide the maximum gross load (vessel + contents + attachments) by the number of support points, then add margin for uneven loading and dynamics — never size to the nominal content weight alone.

• Know the two overload numbers. Safe overload is what the module survives repeatedly without specification loss; ultimate overload is the survival limit. The documented KJT-MKWY002 states 150% FS safe and 200% FS ultimate overload.

• Accuracy is several terms, not one. Non-linearity, hysteresis, repeatability and creep are separate specifications; the KJT-MKWY002 documents ≤0.05%FS non-linearity and ≤0.03%FS for hysteresis, repeatability and creep (30 min) — compare candidate modules term by term.

• Mechanics decide whether the specification survives installation. Thermal expansion, side loads and uneven support destroy weighing accuracy long before the load cell's own limits; a weighing module's mounting kit and stress-relief design exist precisely to manage this.
