Accuracy Class Reference (Maximum Permissible Error, MPE)

• Class 5: ±2.5% (initial), ±5% (in-service)
• Class 10: ±5% (initial), ±10% (in-service)

4-Row Sensor Layout (Enviko Recommended)

• Accuracy Class: Class 5 (±2.5% initial, ±5% in-service)
• Confidence Level: Good
• Description: Ideal for dynamic weigh in motion law enforcement. Offers reliable performance and stable data collection for axle loads and vehicle total weight.
• Best Applications:

             ▪ Weigh In Motion Enforcement

             ▪ Bridge Protection

             ▪ Toll Collection

5-Row Sensor Layout

• Accuracy Class: Class 5 (±2.5% initial, ±5% in-service)
• Confidence Level: High
• Description: Delivers excellent precision and reliability with reduced maintenance. Perfect for high-traffic or critical infrastructure points.
• Best Applications:

             ▪Weigh In Motion Enforcement

             ▪Toll Collection

3-Row Sensor Layout

• Accuracy Class: Class 5
• Confidence Level: Moderate
• Description: Slightly less confidence than the 4-row layout but still meets enforcement-level accuracy. Balances cost and performance.
• Best Applications:

             ▪Weigh In Motion Enforcement

             ▪Bridge Protection

             ▪Toll Collection

             ▪Freight Logistics and Fleet Management

2-Row Sensor Layout

• Accuracy Class: Class 10 (±5% initial, ±10% in-service)
• Description: Designed for non-enforcement scenarios where dynamic axle load screening is needed. Cost-effective and easy to deploy.
• Best Applications:

             ▪Pre-Selection

             ▪Bridge Protection

             ▪Data Collection

1-Row Sensor Layout

• Accuracy Class: Class 10
• Description: Lowest-cost solution. Accuracy depends on road flatness. Suitable for basic traffic monitoring or economical weigh in motion systems.
• Best Applications:

             ▪Traffic Data Collection

             ▪Pre-Selection

             ▪Bridge Protection
