AFFRI 3332 MRSA

AUTOMATIC  ROCKWELL  B R I N E L L  MOTORIZED

AFFRI® introduces a system of automatic hardness tester for the future

Long-time ago AFFRI SYSTEM® successfully overtook the philosophy of dead-weight and of the relative elevating screw of the traditional hardness testers.
-  An increase in the operative performances has been obtained with the use of control load cell in closed-loop (Patent AFFRI® N. 1175158).
- However this improvement appears moderate if we compare it with the high qualitative and operative level reached by AFFRI SYSTEM®.


- A further improvement in performances was achieved when AFFRI® made really automatic the hardness tester working in Rockwell and Brinell tests: only one drive start up and perform - without a break - the phases of positioning, approach and execution of the test.
- The fully automatic operation and the speed in the whole test cycle, obtained by AFFRI SYSTEM®, remains unchanged even in the version with load cell due to the use of unprecedented technologies (patent pending)

MRS SERIES
PERFECT AND EFFECTIVE MEASUREMENTS EVEN AT THE FIRST TEST
ALL OPERATIONS ARE MANAGED BY A SINGLE DRIVE INCLUDING AUTOMATIC CONTACT WITH TEST PIECE
- If you press button Start, 3332 MRS A moves to take contact with test surface and automatically starts the hardness test cycle in automatic succession without a brake.
- Does not require elevating screws
- Meets all laboratory requirements
- Full operation even in presence of vibrations, sudden changes in temperature or dusty environments

SIMPLE AND UNIVERSAL
- Easy and quick Rockwell, Superockwell, Brinell, Vickers measurements in only one machine
- Every environmental condition is tolerable: presence of dust, vibration, changes of temperature, deflection of sample
- With automatic stroke and extension of indenter, it is easy to operate test on internal surface
- Insensitive to deflections
- Automatic compensation of deflection up to 50 mm
- Large fixed base 330x390 mm for sturdy and stable support of test pieces. Small and large size components up to 2000 Kg weight can be tested
- Accessories can be applied on the table to facilitate the positioning of irregular test pieces
- Large Range of test loads from 9.81 to 1839N automatic selectable
- Long stroke from 0 to 500 mm (or higher upon request)
VERY HIGH PERFORMANCE
- Unaltered operation even in extreme conditions: irregular, unfinished, raised or misaligned pieces, all kinds of supports (lifting screw, deformable materials, etc.) presence of impurities (dust, oil, etc.) between the test piece and the support or between the support and the point of the support.
