RSM-SY8(C) Ultrasonic Pile Integrity CT Imaging Tester

4 Pipes 18 Profiles,3D pile tomography

RSM-SY8(C) brings CT imaging to pile testing, enabling 18-section data capture in a single lift. With 3D defect modeling, wireless operation, and intelligent depth counting, it offers unmatched speed, clarity, and precision in foundation inspection.


Introduction

The RSM-SY8(C) is a groundbreaking crosshole sonic logging tester that integrates computed tomography (CT) technology into deep foundation integrity testing. With just one lift, it captures data across 4 tubes and 18 cross-sections, including horizontal and diagonal paths. Equipped with advanced 3D CT imaging software, it reconstructs intuitive, real-time visualizations of pile defects—pinpointing size, range, and location. The system includes a high-speed lifting mechanism (up to 60 m/min), a wireless depth counter, an industrial-grade capacitive touchscreen, and a 9mm ultra-thin high-capacity battery. Designed for rugged field use with IP65 protection, it also supports smart cloud integration via 4G and Wi-Fi, enabling real-time uploads and remote diagnostics.
