The GCTS DataCube is a four-channel, wireless data acquisition unit. This system can accept load cells, pressure transducers, LVDTs, or other analog input signals (strain gages and AC sensors require signal conditioning, sold separately). Each channel features digital offset and gain, 16-bit resolution, and an anti-alias filter.
A wireless device (Android, Apple, or Windows) must be connected to the DataCube via a wireless connection to begin recording data. Once the DataCube begins recording data, the user can disconnect their device. At any time, the user can reconnect their device to view current data or, when the test is over, collect all recorded data. This is ideal for long-term tests as the user will not need to be at the system constantly taking readings. The data can then be easily sent to an email in a spreadsheet attachment.
Various mobile applications are available for specific tests, including consolidation, direct shear, indirect tension, point load, and unconfined compressive strength. A complete list of applications are shown below, and custom apps can be developed. Please contact GCTS for more details.

The soil consolidation apparatus (consolidometer) used to perform the oedometer test is a quintessential laboratory device for any geotechnical testing laboratory and has largely stayed unchanged since its introduction. GCTS has developed a simple data acquisition unit with an app to bring the consolidometer apparatus into the digital age. The DataCube unit with a deformation sensor can monitor and record the specimen deformation after the load has been applied, eliminating the need for the manual recording. The consolidation app saves and plots the data which can be emailed with a touch of a button.
How does it work?
The analog dial gauge on the consolidometer is replaced by a DC type deformation sensor which is then connected to the DataCube unit. One DataCube can accommodate up to four (4) deformation sensors, so a single unit can upgrade up to four (4) consolidometers. The consolidation app on a mobile device (Android, iOS, or Windows) is connected wirelessly to the DataCube to begin recording the data. After each load increment is applied the app records and processes the data. At the end of the test, the mobile device can be re-connected to the DataCube to download and email the test results.
