Applications

Mechatronic Engineers make Universal Testing Machine Model range ME-FE-UTE is designed for testing metals and other materials under Tension, Compression, Bending, Re-Bending, Transverse and Shear Tests. A hardness test on metals can also be conducted. This Special model is designed as Front Open Crosshead for easy Specimen changing with Wedge Action Hydraulic Grips

Accuracy & Calibration

All Mechatronic Engineers make Universal Testing Machines that are closely controlled for sensitivity, accuracy, and calibration during every stage of manufacture. Every Machine is then calibrated over each of its measuring ranges in accordance with the procedure laid down in British Standards BS-1610:Part1:1992 and IS-1828:Part1:1991.
Mechatronic Engineers Universal Testing Machines Comply with grade “A” of BS-1610:Part1:1992 and grade IS-1828:Part1:1991 An accuracy of + 1 % is guaranteed from 20% of the load range selected to full load. Bellow 20% of the selected range, the maximum permissible error is 0.2% of the full reading.

Principle of Operation

Operation of the machine is by hydraulic transmission of load from the test specimen through DIGITAL PRESSURE TRANSDUCER 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 the rupture of test pieces. Load is applied by a hydrostatically lubricated ram. Main cylinder pressure is transmitted to the DIGITAL PRESSURE TRANSDUCER housed in the control panel. The DIGITAL PRESSURE TRANSDUCER gives signal to DIGITAL ELECTRONIC DISPLAY UNIT corresponding to the load exerted by the main ram. Simultaneously the digital Electronic Encoder fitted on the straining unit gives the mechanical displacement to the DIGITAL ELECTRONIC DISPLAY UNIT. Both the signals are processed by Microprocessor and LOAD and DISPLACEMENT is displayed on the to DIGITAL ELECTRONIC DISPLAY UNIT

Electronic Extensometer

Mechatronic Engineers offers electronic extensometer ME-EE-2 to measure material extension with a resolution of one micron. Strain gauge type extensometer to be used up to the elastic limit to determine important parameters like 0.1%, 0.2% proof stress, and Young’s Modulus

Technical Data

  • Gauge Length 25 mm & 50 mm
  • Maximum Extension 2 mm
  • Resolution 1 micron  Specimen Diameter 0.5 to 30 mm
  • Specimen Thickness up to 30 mm  Specimen Width  up to 30 mm

Machine Consists Of 

  • Straining UnitThis consists of a hydraulic cylinder motor with chain and sprocket drive and a table coupled with the ram of the hydraulic cylinder, mounted on to a robust base. The cylinder and the ram are individually lapped to eliminate friction. The upper cross-head is connected to two screwed columns which are driven by a motor. Axial loading of the ram is ensured be reveling the cylinder and ram of any possible side loading by the provision of ball seating.
    Tension test is conducted by gripping the test specimen between the upper and lower cross-heads, Compression, transverse, bending, shear, and hardness tests are conducted between the lower cross head and the table.
    The lower cross-head can be raised or lowered rapidly by operating the screwed columns thus facilitating ease of fixing of the test specimen
  • Control Panel
    The Control Panel consists of a power pack complete with drive motor and an oil tank, control valves with to DIGITAL ELECTRONIC DISPLAY UNIT. A pressure transducer is connected for load indicator and a rotary encoder for elongation with a resolution of 0.1 mm, is provided to measure the deformation of the specimen.
  • Power Pack
    The power pack generates the maximum pressure of 200 kgf/cm2 the hydraulic pump provides continuously non-pulsating oil flow. Hence the load application is very smooth.
  • Hydraulic Controls
    Hand operates wheels are used to control the flow to and from the hydraulic cylinder. The regulation of oil flow is infinitely variable incorporated in the hydraulic system is a regulating valve that maintains a practically constant rate of piston movement. Control by this valve allows extensometer readings to be taken.
    An extra Power pack is used to operate Wedge Action Grips with a hydraulic cylinder by using valve operation. We are providing wired operational remote for hydraulic Wedge action grips with selector switches indicating clamp / de-clamp.
  • Load Deflection Indicator
    It is microcontroller-based advanced electronic control panel connected with a machine using a Pressure Transducer, Rotary Encoder, and Electronic Extensometer. Using RS-232 serial communication port our s/w communicates with the machine and gets real-time Load, Deflection, and Extension, and shows on the computer.
    Electronic digital displays Load Elongation and extension. Facility to hold peak – load and tare facility to make load zero. Elongation display can be set to zero. Optional printer facility. All other facilities maintained under Model UTN. Printer and PC interface.
