Amsler HIT230F for pre-damaging plates (CAI)
The smaller drop weight tester for CAI
With a maximum impact speed of 4.4 m/s and drop weights between 2.04 and 10.2 kg, this drop weight tester is ideally suited for pre-damaging CAI specimens in accordance with various standards. One impressive feature is the excellent test area accessibility, enabling rapid completion of test series. When it comes to efficiency and ergonomics, this drop weight tester can't be beat.
■ Safe, easy, reliable operation.
■ Good test-area accessibility.
■ Design allows easy accessory changes.
■ Intelligent safety system – no need to operate safety door when inserting specimens.
■ Innovative force measurement chain design delivers very low-noise measured values, allowing detailed monitoring of the selective introduction of pre-damage.
■ High (4 MHz) measured-value acquisition-rate combined with high (16-bit) resolution.
■ Drop weight is raised automatically; drop height can be set to any required level from 0.1 m to 1 m.
■ Accurate determination of actual impact speed shortly before point of impact.
■ Mechanical device arrests drop weight after initial impact, preventing multiple impacts.
Range of application
The Amsler HIT230F is ideally equipped for pre-damaging fiber composite plates for the CAI (compression after impact) test currently used in the aerospace industry.
