Product Description:
WLDM‑134 is an electromagnetic‑force‑restoration (EMFR) weighing module, engineered for OEM machine builders and automated precision‑weighing workflows. Covering wide capacities from 30 g up to 6100 g, it delivers outstanding mg‑grade readability that cannot be matched by conventional strain‑gauge load cells.
Equipped with real‑time temperature compensation, the module actively suppresses thermal drift to sustain consistent metrological performance under fluctuating factory ambient conditions. Users can perform on‑site external calibration and assign unique module ID for multi‑sensor system management.
A seven‑level adjustable anti‑vibration digital filter allows flexible tuning of weighing stabilization time. Operators can prioritize faster response for high‑speed dosing or enhance noise suppression for vibration‑prone production environments. Integrated mechanical overload protection safeguards internal electromagnetic components against accidental shock and mis‑operation damage.
With an on‑board digital data collector and standard RS232 interface, WLDM‑134 outputs processed weight data directly to PLC, industrial PC or host indicator without extra signal conversion hardware. Its standardized mounting layout simplifies mechanical embedding into filling equipment, micro‑dispensing stations and inline quality‑control machinery, making it a robust core weighing unit for pharmaceutical, cosmetic, fine‑chemical and premium food‑packaging automation.
