DESCRIPTION

The GCTS Ultrasonic Velocity Test System is a turnkey system and includes everything required to perform Ultrasonic Velocity measurements on laboratory specimens. The system can be programmed to obtain a single measurement or several measurements at prescribed times or any other test parameter available.

The ULT-100 system uses a fast-acting pulser that provides excitation to the ultrasonic sensor and an ultra high speed Analog-to-digital converter for storing the resulting waveforms signals. The sampling rate can be selected from 20 MHz to a sampling rate as low as 156 Hz allowing the user to capture a wide range of ultrasonic signals. With the Automatic gain selection, which can be set from -22 dB to 20 dB, and the Energy Output, Damping and Delay selections that can be manipulated, the user is able to generate ultrasonic waveform in many different scenarios. Also included within the ULT-100 is an 8 channel general purpose data logging device that accepts ±10 VDC signals for recording parameters such as load and displacement. In addition, two 0-10 VDC analog signals supply constant outputs proportional to the P- and S-wave velocities for interfacing with external data loggers.

Within the CATS Ultrasonic software the user is able to digitally control the receiver and pulser ensuring an easy setup and high degree of repeatability

This system is provided with state-of-the-art software developed by GCTS that allows the making of measurements automatically while performing triaxial or unconfined shear loading. The system includes two analog outputs (0-10 VDC) that are proportional to the P and S velocities and can be easily connected to your existing data acquisition or control system. Also integrated is a 16-channel data logger and software to record DC signals from your test equipment. One of these channels can be used to automatically correct for specimen height changes during compression tests. P & S readings can be automatically triggered at time intervals and/or any of the 16 DC input signals.

Included with this system is a set of combination platens designed for both P and S wave velocity measurements. Available platens include models for unconfined loading, soil triaxial loading, and rock (high pressure) triaxial loading.
