CET-100A Weigh-In-Motion Data Logger For Both Quartz And Piezo Sensor

CET-100A: High-Precision Weigh-in-Motion Data Logger for Smart Transportation & Bridge Health Monitoring

In the evolving world of intelligent transportation and infrastructure maintenance, accurate and real-time vehicle weight data is vital. Enviko's CET-100A stands as a cutting-edge solution in Weigh-in-Motion systems, offering superior performance for applications ranging from highway enforcement to Bridge health monitoring.

Why CET-100A?

The CET-100A Weigh-in-Motion data logger is an advanced controller designed to collect analog voltage signals from Piezo sensors, including both quartz and piezo types. These sensors, embedded in roadways, generate precise signals proportional to the axle load of passing vehicles. The CET-100A processes this data in real time, even under complex scenarios such as lane deviation or reverse driving.

Technical Highlights

  The system accommodates large-scale deployments with high sensor density, allowing full-lane coverage and accurate load detection.

• Integrated Charge Amplifier
  Built-in signal conditioning ensures consistent and low-noise data, suitable for both quartz and piezo sensor.

• High-Speed ARM + FPGA Architecture
  Ensures real-time signal acquisition, processing, and reliable decision-making under dynamic traffic conditions.

• Flexible Communication Options
  Equipped with RS232, RS422, and Ethernet interfaces for seamless integration with existing ITS infrastructure.

• Wide Operating Environment Support
  Built to operate under extreme temperatures (-40℃ to 70℃), making it ideal for outdoor roadside cabinets and remote installations.

Versatile Application Scenarios

1. Weigh-in-Motion Enforcement Systems

The CET-100A enables real-time detection of overloaded vehicles, helping transport authorities enforce axle load regulations without stopping traffic. Its precise measurement capabilities minimize false positives and support legal evidence collection.

2. Bridge Health Monitoring

By capturing axle weights and dynamic load data, the CET-100A enhances Bridge health monitoring systems. The long-term load data aids in fatigue analysis, structural assessment, and preventive maintenance planning.

3. Traffic Pattern Analysis

Beyond weight enforcement, the system captures speed, axle configuration, lane number, direction, and acceleration data — supporting traffic planners in designing smarter, safer roads.

Smart Design, Reliable Hardware

Housed in a compact 5U embedded chassis, the CET-100A data logger features a modular backplane design with plug-in boards:

• Main Control Board: Hosts ARM+FPGA core for data processing

• Sensor Acquisition Boards: Handle signal capture from sensors (8 channels per board)

• Interface Board: Provides protected I/O and communication ports

• Power Backplane: Ensures stable power distribution

All components follow Eurocard standards, ensuring reliability and easy maintenance.

Compatibility with Quartz and Piezo Sensors

The CET-100A is optimized for both quartz and Piezo sensors, making it compatible with a wide range of sensor technologies used in modern Weigh-in-Motion systems. Each sensor channel supports signal amplification adjustment, enabling tailored calibration for different site layouts.

Trusted by Transportation Authorities

Already deployed in smart highways and infrastructure projects, CET-100A proves its robustness in high-traffic, mission-critical environments. From Bridge health monitoring to city-level vehicle flow studies, this data logger delivers the data you need — accurately and consistently.
