Enviko offers advanced quartz sensor systems for dynamic vehicle weighing applications. Our weigh-in-motion (WIM) solutions provide accurate, reliable vehicle weight measurement for enforcement, toll collection, and traffic management across various road configurations.

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

Accuracy Class Reference (Maximum Permissible Error, MPE)

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

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