Universal Testing Machine

Technical Specifications :- 

UTMs to be supplied with modern design and features along with more stability and

aesthetics, 

The equipment must have the following features:

Loading accuracy as high as 1% of the indicating value

Strain measurement at variable speed to cover a wide range of materials adjustable by  the manual control valve.

High reading accuracy and rugged design of digital display.

Simple control to facilitate ease of operation.

Fully enclosed and protected load measuring system.

Robust load frame with extremely rigid construction.

Large effective clearance between columns enables testing of standard specimen as well  as structures.

Motor driven threaded columns for UP/DOWN movement of lower crosshead for quick change over of specimen, grips and attachment.

The equipment must be a computerized Universal Testing Machine which has a micro

processor based electronic panel, Precision strain gauge type pressure transducer for load

measurement, Rotary encoder with rack for crosshead displacement/Extension indication,

RS 232 COM port for PC interface, Data entry for specimen dimension, serial number,

gauge length. Unit selection for load, displacement. Results include Load vs

Displacement Curve, Maximum displacement, UTS, % Elongation, Youngs Modulus & Proof Stress

Accuracy And Calibration

Universal Testing Machines should be controlled for precision, accuracy and reliable

calibration during every stage of manufacturing. The machines must be calibrated in accordance with BS:1610( grade A of BS 1610 : 1964 ) and IS standardsgrade 1 of IS : 1828 - 1991. 

The UTM must comply with the following technical specifications
