Tensile strength and elongation are the two prime characteristics of most of the raw materials, whether they are metals or non-metals, such as foam, rubber, textiles, plastic, paper or finished products such as rods, wires, ropes, yarns, belts etcetera. These properties very often play the major role in determining the suitability of any raw material for any specific application. It is therefore, of utmost importance to determine these characteristics accurately, conveniently, and quickly.
TBG Tensile Testing Machine provides a relatively inexpensive way for determining the tensile strength and elongation of variety of raw materials. They are based on constant rate of traverse principle in which one end of the test specimen is held in a stationary grip, while the other end is made to move at a known fixed speed with the help of motor, gear box and screw arrangement. The load exerted on the stationary grip is sensed by a load cell and indicated by a digital load indicator. The controller is microprocessor based and has the facility of over load protection, peak hold and auto calibration. There is a socket in the indicator which is connected to the PC. The load directly indicated in kilograms or Newton.
We provide the Window based software (In Computerized Model Only) which gives the different measurement parameter and the graph between load vs elongation. The report can be printout by using proper printer. The elongation of the test specimen is measured on a digital indicator fixed on the frame of the tester, which indicates the distance between the grips and also in computer screen in computerized model.
The tester is finished in metallic painting and bright chrome, zinc plating to give the apparatus a corrosion resistant finish. It is supplied complied which electrical. Which include micro- switches, Push buttons, and contactors for safe and convenient operation.
