Universal Testing Machine

PENDULUM DYNAMOMETER:
The oil pressure in the main cylinder actuates the special dynamometer system. Pressurised oil in the loading cylinder pushes up the measuring piston proportionately and deflects the pendulum. The piston is constantly rotated to eliminate friction. The system has effect ive damping arrangement to ensure smooth return of pendulum after sudden breakage of test piece. This unit permits selection of favourable hydraulic ratios producing relatively small frictional forces.

LOAD INDICATING SYSTEM:
This system consists of a large dial and a pointer. Displacement of pendulum actuates the rack and pinion mechanism, which operates the load indicating pointer. The pointer moves over a large dial indicating the load. A dummy pointer is provided to register the maximum load reached during the test. Window type dial is provided for easy and clear changing of load range.

AUTOGRAPHIC CONTINUOUS ROLL LOAD ELONGATION RECORDER
A continuous roll ( A strip chart ) type load•elongation recorder is provided for plotting load•elongation graph. Horizontal movement of the rack produces load ordinate of the diagram and drum rotation to elongation ordinate, in the ratio of either 1:5 or HO,

ELECTRONIC UNIVERSAL TESTING MACHINE
Construction : Aditya make electronic Universal Testing machines comprise of
Loading Unit :-This is similar to standard loading unit of analogue type universal testing machine In addition to standard features of regular loading unit. a ROTARY ENCODER is attached to the hydraulic ram to get accurate displacement of the ram.

Measuring Control Panel:
This includes.

• Highly precision, sealed and very accurate pressure transducer mounted on the hydraulic pressure line of the loading unit.
• Highly stable data ACQUISITION system to convert Analogue output of pressure transducer into equivalent Digital Data.

Digital Signal Processing Unit:
This is a state of the art. MICROPROCESSOR based signal processor which operates on Digital oip signal from Data ACQUISITION part and displays the test results on large digital displays. This also handles relevant claculations to got. UTS value. cvo Displacement. Break load etc.

Keyboard/Display Panel:
This is ergonomically designed for best interaction between operator and the machine. This incorporates sealed MEMBRANE type keyboard for data feeding & large display (or load & displacement. Apart from above a parallel printer port & RS232 serial communication port is also incorporated. Through the printer port a Dot Matrix printer can be attached to get stress / strain curves as well as other test results. RS 232 port can be used for PC interface and hence to add variety of application softwares.

ACCURACY AND CALIBRATION:
Aditya Universal Testing Machines are precisely controlled for accuracy and reliable calibration during every stage of manufacture. The machines are cali-brated in accordance with B.S.:1610 and I.S.:1828. An accuracy of +1% is guaranteed from 20% of the load range selected to full load. Below 20% of the selected range the maximum permissible error is 0.2% of the full load reading.
