Cross Hole Ultrasonic Monitor

Description

The CHUM (Cross Hole Ultrasonic Monitor) uses the Crosshole Sonic Logging, CSL testing method to perform high-resolution quality control of deep foundations.

The system uses an ultrasonic wave sent from a transmitter to a receiver pulled through water-filled access tubes embedded in the concrete. The measured arrival time and energy are strongly dependent on concrete quality.

Applications

For testing pile integrity using the CSL method, of medium to large size piles, with supporting access tubes.

What makes CHUM cross-hole logger, the fastest CSL testing equipment?

  • Easy to use

– Usually, no training is needed, and the system can be self-taught in hours. (No expensive training days)

– Supports AGC (Automatic Gain Control) for simple, fast, and accurate performance in dynamic conditions.

  • Tomography

– 2D tomography (included).

– 3D tomography provided as a service

– Three alternative tomography methods: Fuzzy logic, Parametric and 3D

– In real-time tomography: the shape of the defects forms as the probes are pulled

  • Modular design

– CHUM connects to any PC via the standard USB port. It will connect to future computers (such as Origami) while embedded systems will quickly become outdated.

  • Reliable

– 100% QA tests at 16-atmosphere pressure, vibration, and extreme temperature

– The CHUM case can tolerate drops and shocks

– Rugged connectors, PU cables, and details.
