Arun’s range of Universal Testing Machines are widely appreciated in different industries for the following features:
Loading accuracy as high as ±1%.
Training roll autographic recorder supplied as standard to enable study of the behavior of materials.
High reading accuracy due to large size and design of dial.
Wide range of standard and special accessories, including load stabilizer. Easy change from plain to threaded and screwed specimens.
Motorised loading and unloading cycle.
Large effective clearance between columns enables testing of standard specimens as well as structures.
Simple controls for ease of operation.
Safe operation ensured by means of safety devices.
Fully enclosed and protected pendulum.
Principle of Operations
Operation of the machine is by hydraulic transmission of load from the test specimen to a separately housed load indicator. The system is ideal since it replaces transmission of load : through levers and knife edges, which are prone to wear and damage due to shock on rupture of test pieces. Load is applied by a hydrostatically lubricated ram. Main cylinder pressure is transmitted to the cylinder of the pendulum dynamometer system housed in the control panel. The cylinder of the dynamometer is also of self – lubricating design. The load transmitted to the cylinder of the dynamometer is transferred through a leverage to the pendulum. Displacement of the pendulum actuates the rack and pinion mechanism which operates the load indicator pointer and the autographic recorder. The deflection of the pendulum represent the absolute load applied on the test specimen. Return movement of the pendulum is effectively damped to absorb energy in the event of sudden breakage of the specimen.
Machine consists of:
• Straining Unit • Control Panel Power Pack • Hydraulic Controls • Load Indicator System • Automatic Continuous Roll Load – Elongation Recorder
Extensometer is essential to measure the elongation of test specimen under load, to have its mechanical properties. Mechatronic Control System’s Extensometer Model EM 1 is intended to serve the above purpose.
