Application


'DTI' Electronic Universal Testing Machine is designed for testing Ferrous & Non-Ferrous materials under tension, compression bending, transverse and shear loads. Hardness test on metals can also conducted.

Principal of Operation for

Model UTES-FL
UTM right control valve is Servo Controlled in close loop mode as per mode selection. Following control modes available
  • Standard Manual control
  • Load rate control
  • Elongation rate control
  • Load hold mode

Also Auto start & initial value open start options are available for test start to take care of slippage & different specimen types. 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 encoder fitted on the straining unit gives the mechanical displacement.

  • Online graph of load Vs Displacement directly on screen
  • USB Printer port for printer interface with graph & result print out
  • Facility to export the result/ Data to PDF, EXCEL & CSV formats
  • Windows based software available for Online graph on PC, Data analysis, Statistics, Point tracing, superimposing graphs to compare with standard, zooming graph etc.


Machine Consists of Straining Unit

This consists of a 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 rigidly fixed to the table by two strengthened columns.

The lower cross-head is connected to two screwed columns which are driven by a motor. Axial loading of the ram is ensured by relieving the cylinder and ram of any possible side loading by the provision of ball seating. A Rotary Encoder of minimum resolution of 0.01 mm is provided to measure the deformation of the specimen. 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.

Typical HGFL design includes a basic universal testing machine frame with open type crossheads and hydraulic wedge action grips.


Control Panel

The Control Panel consists of a power pack complete with dhve motor and an oil tank, control valves and electronic display unit.

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 operated wheels are used to control the flow to and from the hydraulic cylinder. The regulation of the oil flow is infinitely variable. Incorporated in the hydraulic system is a regulating valve, which maintains a practically constant rate of piston movement. Control by this valve allows extensometer reading to be taken.

Another Power pack is used to operate wedge action grips by means of hydraulic cylinder by using solenoid valve operation. For Hydraulic Wedge action grips separate control remote is provided with selector switches indicating clamp - declamp and null positions.


Accuracy & Calibration

DTI Electronic Universal testing machine is closely controlled for sensitivity, accuracy and calibration during every stage of manufacture. Machine is calibrated over each of its measuring range in accordance with the procedure laid down in British standards 1610: Part1: 1992 and IS 1828: Part1: 1991.

'DTI Electronic Universal Testing Machine' complies with Grade "A" of BS: 1610:Part1:1992 and class 1 of IS-1828-Part1:1991.
