Cross Hole Ultrasonic Monitor
For CSL Test

Introduction

The CHUM (Cross Hole Ultrasonic Monitor) conducts high-resolution quality control of deep foundations using the Crosshole Sonic Logging (CSL) method. This technique transmits ultrasonic waves from a sender to a receiver through water-filled access tubes embedded in concrete. The wave's arrival time and energy indicate concrete quality. Ougan Cross Hole Ultrasonic Monitor features a 12-inch high-resolution display, WinCE OS, 4-channel control, Bluetooth connectivity, and real-time data upload. It supports efficient pile quality testing and precise analysis.

Cross Hole Ultrasonic Monitor
Features
  • Built-in  industrial  instrument  dedicated  industrial  control computer with a high-resolution 12-inch color lcd display for field use.

  • Based on the WinCE embedded operating system,stable and reliable,supports USB flash drive for system startup and recovery.

  • Fully laminated capacitive touchscreen.

  • Bluetooth wireless+wired connection depth counter.

  • Touchscreen operation,compatible  with mouse and keyboard, built-in large analog input panel,supports Chinese.

  • Multiple sonic tubes forming a profile for one-time completion of detection.

  • Sampling while simultaneously displaying image maps (or waveform charts, wave velocity and amplitude curves,tables).

  • Adjustment of magnification, delay time, judgment threshold, and sampling step size is possible simultaneously during sampling.

  • Pause and rewind are available during sampling, enhancing the pre-sampling trial function.

  • Customization of the data acquisition software window position and interface colors is possible.

  • Supports data upload to multiple platforms.

  • The analysis software supports the Windows operating system, featuring a unified style,user-friendly interface, convenient operation, rich functionality,standardized processing, and automatic generation of report charts. It also provides interfaces for exporting to Word, Excel, BMP images, and more.
