Working Principle
Fix the test head of Brinell hardness tester to the test frame. When testing, fix the measuring frame onto the surface of the test piece firmly, load force by operating the handle.
The test head is a mini hydraulic system which contains a control valve for controlling force. When force loading to 3000Kgf, the control valve opens, pressure releasing. According to ASTM standard, force loading should be repeated 3 to 4 times, keeping the pin of the pressure gauge reaching the point of 3,000Kgf 3 to 4 times. ln this way, it equals the test regulation of test force 3,000 Kgf, iDmm test ball, force maintaining time; 0 to 5 seconds.
Instrument Features
Test principle:
Apply hydraulic principle permitting loading 3000kgf manually.
On-site Testing:
It could be applied in workshop, simple operation, easy carrying, and testing body hardness of large parts piece by piece.
Permanent Indentation:
By 3000Kgf and 10mm test ball, the indentation is permanent for re-inspecting.
High Reliability:
It follows Brinell hardness test method completely, the same as desk testers, reflecting the actual mechanical property of material or parts.
High Accuracy:
Indication error, repeatability error and test force accuracy comply with ISO, and ASTM standards, the same as desk testers.
Wide Application Range:
As long as clamped to the parts, it could test parts in any shape and size.
Wide Test Range:
It could test various common metal materials by its combination of different test force and test head, that is, wide test range.
Application
- On-site test of steel products, nonferrous metal, castings, forgings, and semi-finished heat treatment parts.
- Applied to too large parts for desk testers to test. Replace Leeb testers which are in low accuracy and reliability.
- Indentation could be read by indentation automatic measurement system and hardness valves displayed directly.
