Performance Evaluation and Certification for Checkweighing Equipment
Performance evaluation and certification for checkweighing equipment is a critical process for ensuring product quality, legal compliance, and operational efficiency. Unlike static scales, checkweighers weigh products in motion, which introduces unique variables that must be carefully managed.
Attribute Value
Weighing Tolerance ±0.1–0.5% of target weight (varies by class)
Minimum Divisor (e) e = 1–10g (for Class III)
Throughput Rate 100–600 units/minute (depends on conveyor speed)
Stabilization Time ≤2 seconds (for dynamic weighing)
Frequency Weekly (high-use) or Quarterly (low-use)
Auto-Calibration Temperature-triggered or time-based (if equipped)
Temperature Range 0°C to 40°C (operational), -20°C to 60°C (storage)
Vibration Resistance ±0.2g (ISO 10816-3 for industrial vibration)
Conveyor Speed 0.1–1.5 m/s (adjustable)
Overload Capacity 120% of max capacity (safety limit)
EMC Compliance Reject Mechanism
Power Supply 24V DC ±5% or 100–240V AC, 50/60Hz
Repeatability ±0.05–0.2% of target weight (10 consecutive tests)
Linearity Error ±0.1–0.3% of full scale
Legal-for-Trade NTEP (US), MID 2014/32/EU (Europe), OIML R51 (Global)
Material Safety FDA-compliant (if food contact), Stainless Steel 316
Data Logging Timestamp, weight, batch ID (CSV/PDF export)
Reject Mechanism Pneumatic/mechanical (response time ≤100ms)
Key Components of Performance Evaluation
1. Initial Assessment and Mechanical Inspection
Before any tests begin, a thorough physical inspection is necessary to ensure the checkweigher's fundamental components are in good working order and not causing measurement errors.
  • Visual Check: Inspect the conveyor belts, weigh platform, and frame for any signs of damage, wear, or debris. The weigh platform must be free-floating and not touching any surrounding parts.
  • Component Integrity: Check for loose bolts, screws, or wiring. The load cell, which is the heart of the weighing system, must be secure and undamaged.
  • Environmental Factors: The checkweigher's performance is sensitive to its environment. Factors like vibration from other machinery, temperature, and humidity can all affect accuracy.
2. Calibration and Verification
Calibration adjusts the checkweigher to ensure correct measurements, while verification confirms the system's accuracy and consistency.
  • Static Calibration: Preliminary calibration with certified test weights while the conveyor is stopped to establish baseline accuracy.
  • Dynamic Calibration: Crucial test where a known product is passed over the moving conveyor multiple times to confirm motion weighing accuracy.
  • Repeatability Test: A single product of known weight is run through multiple times to check consistency within tight tolerances.
  • Corner Load Test: Weight is placed at different corners of the weigh platform to verify performance of all load cells.
