Elastic Modulus on Rocks

It can be used with a Matest high stability frame with capacity of 2000, or 3000 kN coupled to the Automatic Servo-controlled system “Servo-Plus Evolution” (mod. C104N).

The appliance includes:
• Hydraulic system
It is an hydraulic installation and has a high performance valve directly controlled by the digital unit that grants the automatic control of the pace rate increasing the load, keeps a certain load and than controls the pace rate decreasing the load.
The setting of the pace rate is made by a very sensitive valve controlled by a step by step motor and it allows a micrometric action on the pace rate granting excellent results.
A laser position detector allows a rapid positioning of the piston. This grants a touching sensitivity of test starting of about 0.1 per thousand of the maximum capacity.
