Principle of operation is based on Closed loop Principle. The Close loop Principle is:

• A signal is generated on the ramp genera- tor. Feedback signal is generated by the system. Both the Signals are processed at a speed of 10kHz in P.I.D. controller. Resultant Signal is passed on to the Servo Valve keep- ing the system within + 2% of the Programmed value.

Power Pack:

• Power pack is placed by the side of the loading unit and is connected to the main unit through quick-couplings. It is powered by a single phase motor to load the unit to its maximum capacity. It has provision for fast lift and also for the selection between compression unit or flexure unit.

Fixture for Testing Small Cubes:

• Fixture is made as per EN-196, for the test- ing of small cubes. It has a free moving spring loaded spherical seating. Bottom part of the fixture can accommodates cubes upto 50 mm.

Loading Frame:

• Load frame is steel welded. It is designed to withstand a few million times of full cycles of loading without any sign of distortion or fatigue. These frames are light in weight. The base carries a fine finished hydraulic ram and the lower platen.
• The top plate has a spherical seating to take care of any irregularity of the specimen sur- face or slight misplacement of the specimen from the central axis. Front cover is made of expanded sheet, which is provided as a pro- tection to the operator while at the same time giving an unobstructive view
