Analogue Universal Testing Machine

Features : Universal Testing Machine have a wide range of applications. A number of materials, metals in different form and shapes can be tested for variety of tests like Tension, Compression, Transverse, Bend, Shear, Brinell Hardness etc. Special attachments are also available for testing of Flat Belts, Chain Links, and Wire Ropes etc.

Loading Optinal Accessories : Mechanical Extensometer, Load-Stabilizer, Attachments for Brinell test, Tensile test for shouldered & threaded, Single & Double shear test, Bolts-Nuts & Washer test, Rope test, Flat Belt test, Bend-Rebend test, 180° Bend test, Pull-Out test, etc. are available.

Capacities from 100 KN to 2000 KN.( i.e. 10T to 200T)

Loading accuracy well within ±1% conforms to IS: 1828 / BS: 1610

Loading Frame : The base has a hydraulic cylinder at its centre and two main screws at both ends. The middle cross head is mounted on screws through main nuts. the middle cross head can be moved up or down through chain transmission and geared motor to adjust the initial tensile compression clearance. On the piston, rests an assembly of upper, lower cross head and two columns. The individually lapped cylinder piston assembly ensures smooth axial force with minimum friction.

Control panel : Hydraulic circuit - it consists of hydraulic power pack which has a directly driven radial plunger pump which gives a continuous non pulsating flow of oil pressure up to 250 bars. a pressure compensated needle type flow control valve is provided to control the oil flow to cylinder there by achieving a desired piston speed. Infinitely variable speeds an be obtained with help of valves. Optionally this can be controlled from electronic control system.

Load Measurement System : The oil pressure in the main cylinder is also transferred to an electronic pressure transducer which goes proportionate signal to computer electronic unit. Both the motors for hydraulic operation and cross head motion are controlled by buttons on electronic control system and they have interlocks to prevent simultaneous working of motors. The electrical panel is housed in control panel. Displacement measurement is carried out by means of a rack and pinion on rotary encoder. Encoder signal is fed to electronic control system to get displacement.

Operation : Tension test is conducted by gripping the test specimen in the upper and middle cross head. Compression, Bending, Transverse, Shear and Hardness tests are conducted between the middle and lower cross head by using appropriate fixtures. The rapid adjustment of middle cross head facilities easy fixing of tensile I Compression specimens of different lengths.

Hydraulic controls are through hand operated valves, ergonomically placed for ease of control. Optionally valves can be controlled from electronic control system. Adequate safeties for over load and over travel are incorporated and emergency switch is provided.

Accuracy & Calibration : Every machine is calibrated in accordance with procedure laid down in BS - 1610 - 1964 IS 1828 - 1991. 'FINE' Computerised Universal Testing Machines comply with grade A of BS 161()"1964 and Grade 1.0 of IS 1828 - 1991. An accuracy of + -1% guaranteed from 2% to 100% of capacity of the machine. in the Computerised UTM, the computer is an integral part of the entire system and not just on ADD - ON feature. This puts a lot of power and versatility into the hands of the operator and makes the system much more self contained than usual, as it includes many functions usually only available as additional ( often expensive) optional features.
