Affri LD 3000 Brinell Hardness Tester
Semi-automatic Brinell hardness tester. Reading of indentation is made through standard microscope or through optional electronic microscope with auto-measure. Indent only model.
TEST LOADS: from 10 to 3000 kgf (From 98,07 to 29421 N)
FEASIBLE TESTS: (Depending on the models, for more information see the table at the bottom):
Brinell HBW: 1/10 - 1/30 - 2.5/62.5 - 2.5/187.5 - 5/25 - 5/62,5 - 5/125 - 5/250 - 5/750 - 10/100 - 10/250 - 10/500 - 10/1000 - 10/1500 - 10/3000
Brinell HBWT: 2.5/62.5 - 2.5/187.5 - 5/125 - 5/250 - 5/750 - 10/500 - 10/1000 - 10/1500 - 10/3000
Rockwell: HRA - HRB - HRC - HRD - HRF - HRG - HRL - HRM - HRR
Vickers HV 3 - HV 5 - HV 10 - HV: 20 - HV 30 - HV 50 - HV 100 (Only indentation)
EASY AND FAST AUTOMATIC MEASUREMENTS:
Spin the levelling screw’s handle and bring your sample to make contact with the clamping hood blocking the piece. Press the START button and the measuring head approaches the sample, applies the load to perform the indentation and goes back upward; all in automatic succession without breaching a phase.
CLOSED LOOP TECHNOLOGY (Pat. AFFRI):
Load forces are applied through load cells and electronically controlled in “Closed Loop” with a frequency of 1 khz, assuring perfect linearity in every range. Range from 10 to 3000 Kgf. Results are not affected by any misalignment, vibration or problems associated with dead weight systems on traditional testers. The tester can also run in an inclined position.
SELF COMPENSATING AND CLAMPING SYSTEM (Pat. AFFRI).
When testing unstable samples or defective parts, the AFFRI System will follow the sample and not lose contact, compensating any frame deflection during the test cycle. Accurate results are assured even with oiled, dusty or dirty pieces.
VERTICAL STROKE:
The measuring head with indenter has a vertical stroke of 30mm. The indenter head retracts into a protective cylinder at the end of the measurement cycle.
