Hoek cell - How-to set up rock triaxial testing - Wykeham Farrance | CONTROLS Group

Rock triaxial testing are perfomed using the Hoek cell: a stainless steel chamber filled with oil for the application of confining pressure through a rubber sealing sleeve. Axial and radial strain measurements are taken using electric strain gauges glued directly onto the cylindrical specimen. At the end of the assembly the cell will be placed on the compression machine platen for Elastic Modulus and Poisson's Ratio determination.

Very good video. Thanks for sharing it. Is it necessary to leave the displacement transducers in the frame? What are the use of knobs on these transducers? Thank you!

Thanks Alireza.
Our product manager responsible for this equipment suggests to remove the displacement transducers after performing the test, just to be more comfortable while the Hoek cell is removed from the compression frame.
Please consider that it is necessary to position the displacement transducers as vertical as possible. The knob on the magnetic holder can be used for small adjustments allowing precise inclination variation of the device.
For any further help please do not hesitate to contact [e-mail]
