UNIVERSAL TESTING MACHINE: Analog/ Digital/ Computerised

AS PER IS: 1828 & BS 1610.

Introduction: Universal Testing Machine is designed for testing metals and other materials under tension, compression bending, transverse and shear loads. Hardness test on metals can also conducted.

Operation of the machine is by hydraulic transmission of load from the test specimen through pressure transducer to a separately house 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 pressure transducer housed in the control panel. The transducer gives the signal to the electronic display unit corresponding to the load exerted by the main ram. Simultaneously the digital electronic fitted on the straining unit gives the mechanical displacement to the electronic display unit. Both the signals are processed by the microprocessor and load and displacement is displayed on the digital readouts simultaneously.

Electronic Control Unit : Consists of

• Microprocessor based panel incorporating state of art technology with following features.
• Front panel membrane type key board for machine operation with numeric keys for data entry.
• Data entry with numeric keyboard of test parameters including speeds, rupture % peak, preload, modulus data, test data & specimen data etc.
• 20 input data set storage, 50 results storage maintains data results during power off.
• Batch test facility for generating batch & statistic result using same data set.
• RS 232C serial port, Optional windows based software available for Online graph on PC. Data analysis, statistics, point tracing superimposing graphs to compare with standard, zooming graph etc.
• Printer port for printer interface with.
  • Graph & result printout. Test certificate printout .
  • Batch Certificate printout .Simple statistic printout.
