Product Description

UTM is suitable to conduct following tests - (i) Compression (ii) Tension (iii) Transverse (iv)Bending (v) Shear (vi) Hardness and many others on various types of ferrous and non-ferrous materials conforming to testing procedure laid down in IS/ ASTM etc. standards.

Electronic Universal Testing Machine (HL 590 (FL) with open crosshead and front loading jaws)

Electronic range of UTM's are fast, accurate & simple to operate. In these machines load and displacement are displayed on the digital display unit or monitor in the respective engineering units. connectivity to computer for real time transfer data to computer. When connected to computer online graph can be displayed on the screen. These machines are supported by windows based user friendly software which can store, retrieve readings as and when required.

• Safety features like over travel limit for central cross head, over travel limit for ram and over loading of the system should be provided as standard in the machine.

The machine comprise of three main parts.

1. LOADING FRAME
2. HYDRAULIC PUMPING SYSTEM
3. ELECTRONIC CONTROL PANEL

LOADING FRAME

The Loading Frame consists of a central cross head whose position is adjustable through a geared motor depending on the size of the test specimen. The lower table is carried by the piston of the Hydraulic Ram of suitable capacity positioned in the cast iron base of the machine. The upper cross head is carried by four steel columns fixed to the lower table. The machine have six pillars in total for stability and rigidly. Compression, transverse, bending, shear and hardness tests are carried out between the central cross head and lower table while the tension test is carried between the central and upper cross heads.

Sensing of load is through a strain gauge based transducers, while the movement of the lower table (ram Stroke) is measured by rotary encoder.

Safety features like over travel limit for central cross head, over travel limit for ram and over loading of the system are provided as standard with the machines.

HYDRAULIC PUMPING SYSTEM

Hydraulic pumping system consists of multi plunger pump powered by a suitable motor operated on 415V, 3Phase, 50Hz. This pump gives a continuous non pulsating oil flow to the ram of the loading frame. Pressure switch is provided for additional safety against over load. Release valve and load control valve is placed at a convenient position for easy operation by the operator.

It also have electrical control panel for the movement of the middle cross head and also for ON/OFF of the main pump. Additional switch is provided for fast lift of the ram for initial filling of the gap.

Load Pacing

The system is supplied with manual pacing arrangement with status of pace rate is indicated in the digital display unit. Pace rate is achieved manually by controlling the flow control knob and the system is released manually after the peak load is achieved.

ELECTRONIC CONTROL PANEL

It is a microprocessor based unit with a built-in interface for the computer. The panel consists of a load indicator, elongation indicator and an output analog port for X-Y/t plotter. It has the facility for Tare, Peak Hold, Auto zero, Auto ranging, i.e. automatic shifting of range from lower to higher after the load reaches the set limit and reset button, Start and stop of transferring data to computer. The readings of Load and Elongation can be transferred to computer through RS 232 port and can be online monitored.

Application Software

User friendly Software would be provided with the system to acquire and plot data online and then analyze the various result parameters.

• Windows based & user friendly � On line display of Load & Displacement
• Saving & Retrieving of Test Files � Start & Stop operation for acquiring data
• Online Plot of Load v/s Displacement Graph � Display of recorded Data on the Screen
• Storing of Data in Numeric form

Calculation of various parameters (Tensile Strength, Young's Modulus, Yield Stress, Ultimate Stress, Max. Strain etc.)
