auto electromechanical drop weight tester
5" TFT TOUCH SCREEN CONTROLLER
Spherical steel ball should have a mass of 1 ± 0.01 kg,
The container should be at least 100 mm thick, where a bed of silica sand (with a grain size between 2 mm and 0.076 mm) can be placed. With dimensions of 400mm × 400mm × 150mm. The container must have a device for centering the sample. It should have a metal column 1.5 m long, graduated at 50 mm intervals and attached to the container. Sliding frame with a device attached to the metal column and capable of dropping the steel ball in the vertical direction (for this purpose, an electromagnetic system can be used). Since determining the height of h with a manual arm is not very sensitive, the process of determining the height should be with a digital display panel with the help of an electronic sensor. Instead of the turning lever, there should be a motorized mechanism to move the ball retainer up and down. When we enter the height value and press the button, the device should automatically reach the desired height with a precision of 0.01 cm. Approx Weight : 250 kg. Electrical : 220 V, 50 Hz, 1 phase.
