MODEL FT-3137

12-Ch CONSTANT STRESS/STRAIN
FATIGUE TESTER
限りある資源と美しい自然を大切にOutline
The 12-Ch Constant Stress/Strain Fatigue Tester applies
constant strain oscillation to up to twelve dumbbellshaped test pieces while a static load or elongation s
being applied. It counts the number of cycles until thesamples are broken. The load applied to the sample ismonitored in real-time on a PC screen during a constantstrain test, and elongation is monitored in a constantstress test. By a constant stress test, variation of test resultscaused by the slack of the test piece (buckling) can be
minimized,
obtaining
more
accurate
fatiguecharacteristics of materials and enabling fatigue tests
with better correlation to actual products.

Features〇 A test can be performed on up to twelve test pieces simultaneously.
〇 Having a breakage detection device for each channel, it counts a number of strokes until breakage
and stops operation when all the test pieces are broken.
〇 An S-N curve (presentation of load to the number of strokes, or elongation to the number of strokes) isdisplayed in real-time on a PC screen during a test.
〇 Test results can be saved as CSV files.
〇 A rotary handle is attached for easy setting of test pieces on the chucks.
