Hamburg Wheel Tracker Verification/Calibration System

InstroTek HWT-Pro: The Gold Standard in Hamburg Wheel Tracker Verification and Calibration

The Definitive Solution for Fast, Accurate Verification, Calibration, and Diagnostics for Your Hamburg Wheel Tracker Patent No. 10,753,838

Introducing the InstroTek HWT-Pro, a state-of-the-art, comprehensive diagnostic and verification system designed specifically for the Hamburg Wheel Tracker. This advanced device empowers you to meticulously measure and report your machine's deviation from the stringent AASHTO T-324 calibration requirements. Developed in line with the recommendations of NCHRP Project 20-07 Task 361 from Louisiana State University, the HWT-Pro is the industry's only device that provides a complete, precise, and actionable overview of your Hamburg Wheel Tracker's performance.

With the HWT-Pro, you can effortlessly measure all critical parameters, including:

• Wheel Load: Static and dynamic measurements to ensure accurate force application.
• Wheel Position & Speed: Verifies the wheel's location along its path, including the center point, and tracks its velocity.
• Waveform Analysis: Measures the dynamic wheel load and compares it to a true sinusoidal wave, reporting the Root Mean Square Error (RMSE) for unparalleled accuracy.
• Rut Depth (Displacement): Precisely measures LVDT displacement to verify rut depth readings.
• Water Temperature: Ensures the testing environment meets specification requirements.

The HWT-Pro isn't just a verification tool; it’s a proactive maintenance and diagnostic powerhouse.

HWT-Pro Spec PC Software: Seamless Data Capture and Reporting

The intuitive HWT-Spec PC Software is the central hub for all data captured by the HWT-Pro. The software guides users through a step-by-step verification process, systematically collecting critical data.

• The HWT-Pro Load Sensor captures wheel load (static and dynamic), position, speed, and waveform data via a simple USB connection.
• The HWT-Pro Height Indicator provides a safe and reliable method for measuring LVDT displacement. A unique three-point displacement measurement is taken directly under the wheel, providing a more realistic and accurate verification of rut depth.
• A NIST traceable temperature indicator captures precise water temperature at any location along the wheel path.

Upon completion, the software generates a comprehensive HWT-Pro Verification Report, which includes a clear pass/fail summary of the Hamburg’s conformity to AASHTO T-324 and provides a graphical comparison of the wheel's movement against the ideal sinusoid wave shape.

HWT-Pro Kit: Everything You Need in One Package

The complete HWT-Pro system is delivered in a durable, professional carrying case and includes:

• Load and Height Verification Devices
• Sample Tray Centering Spacers (compatible with different wheel tracker models)
• NIST Traceable Temperature Indicator
• USB Cable
• HWT-Spec Software License

Crafted from precision-machined stainless steel and high-quality electrical components, the HWT-Pro is built for durability and long-term reliability. All measurement devices included in the kit are NIST traceable, and the unit ships with a full calibration certificate.

The Ultimate Diagnostic Tool for Your Hamburg Wheel Tracker

The HWT-Pro is far more than a simple verification device. Equipment malfunctions and deviations from calibration standards are common sources of inaccurate test results. The Hamburg Wheel Tracker is a complex machine with numerous moving parts that can wear over time. Extended periods of non-use, such as before or after a busy construction season, can also cause systems to drift out of calibration.

The HWT-Pro enables you to:

• Proactively Verify Performance: Confirm that all calibration parameters are within spec before starting a critical project.
• Diagnose Issues Quickly: Identify specific problems with your Hamburg Wheel Tracker that could be affecting test results.
• Track Performance Over Time: Monitor changes in your machine's performance, allowing for predictive maintenance and identifying parts that may need replacement, thus extending the life of your equipment.

Key Benefits of the InstroTek HWT-Pro System:

• Comprehensive Verification: Verifies all measurement requirements of AASHTO T-324.
• Industry-Approved: Meets the recommendations of NCHRP Project 20-07 Task 361.
• Enhanced Safety: Allows for easy and safe verification of the unit without placing hands near the moving wheel and heavy loads.
• Multi-Parameter Measurement: Accurately measures wheel load (static & dynamic), wheel center point, waveform, displacement, and water temperature.
• Unmatched Accuracy: Checks the fidelity of the wheel's motion against a true sinusoid and reports RMSE.
• Quality Assurance: Check calibration quality before a project or after long periods of non-use.
• Efficient Troubleshooting: Quickly diagnose and resolve issues with your equipment to minimize downtime.
• User-Friendly Reporting: The HWT-Spec PC Software makes it simple to capture and report verification results.
