Checkweigher Systems for Accurate In-Line Product Weight Control
Upgrade your production lines with certified checkweighers supplied by ZFA to improve weighing accuracy, reduce product loss, and strengthen quality control across food, pharma, chemical, and consumer goods industries.
An automatic checkweigher (also termed an in-line checkweigher machine, dynamic conveyor scale, or continuous checkweigher) inspects package weights in real-time on high-speed packaging lines. It verifies product tolerances, eliminates underweight packages, minimizes product giveaway, and automates high-speed reject sorting without slowing operations.
-
In-Line Dynamic Weighing & Load Cells: Powered by high-speed digital strain gauge or EMFR (Electro-Magnetic Force Restoration) load cells to measure discrete packages across conveyor belts up to 300+ packs per minute.
-
Automatic Sorting & Rejector Mechanisms: Integrated with high-speed pneumatic pushers, air blast jets, drop gates, and flipper sorting systems to segregate off-spec or contaminated containers instantly.
-
Combination Inspection Systems: Integrates in-line metal detection, X-ray scanning, and visual barcode inspection with dynamic checkweighing for all-in-one product safety and contaminant validation.
- Product Memory: Stores up to 1,000 product configurations for faster setup and changeovers.
-
Sanitary Stainless Washdown Construction: Built with 304/316 stainless steel open-frame architecture and IP65/IP69K washdown enclosures compliant with sanitary food processing, dairy, meat, and pharma hygiene standards.
-
Statistical Process Control (SPC) & Filler Feedback: Touchscreen HMI displays provide real-time weight trends, standard deviation tracking, and automated feedback loops to adjust upstream volumetric filling machines.
-
Trade Metrology & Regional Compliance: Delivers audit-ready compliance for OIML R51, MID, e-mark (Average Weight Legislation), HACCP, and GMP across Egypt, Saudi Arabia, the UAE, and the GCC.
