Measurements and Extensometer:

Principles of Measurements:

Concepts for describing aspects of nature by numbers are called physical quantities. Examples may range from counting fruit to reading a thermometer gauge to determine temperature.

Acquiring such a number, a set of such numbers or related numbers directly from a natural system is called measurement.

In technical analysis, An intangible principle for finding minimum security price targets for traders. The measuring principle uses technical analysis to analyse chart patterns to detect stock levels that, if broken, could lead to a small down leg. More specifically, it allows traders to set a reasonable minimum price target on a stock by weighing the movements of the stock chart pattern against each other.

Mechanical Extensometer:


It is an attachment to Universal Testing Machine and Tensile Testing Machines, used to find out the proof stress at the required elongation percentage.

It measures the elongation of a test piece on load for the set gauge length.

Least count of measurement 0.01 mm and maximum elongation measured upto 3 mm.

Adjustable gauge length from 30 mm to 120 mm

Round specimen from 1 mm to 20 mm dia and flat specimen from 1 mm to 20 mm thickness can be accommodated.



Our precision engineered mechanical extensometer measures elongation of test specimen under load. Our mechanical extensometer comprises of two long knife edges at top, two indicators and lower knife edges to actuate the dials. The bars are pressed against the specimen by means of clamps to ensure that the knife edges bite the specimen to avoid any slip. The under edges are adjustable to provide different gauge lengths for measurement. As deformation takes place the lower knife edges transfer the movement to the dial gauges and the deformation of specimen is shown on dials, so that the change in length of specimen by 1/100 mm. Equals to one division of the graduation of dial.
