Tensile Testing Machine
Product Details:

•  Tensile strength and elongation are the two prime characteristics of most of the raw materials, whether they are metals; or non metals such as rubber, leather, textiles, plastic, paper; or finished products such as rods, wires, ropes, yarns, belts etceteras. These two properties often play a major role in determining the suitability of any raw material for any specified application. It is, therefore, of utmost importance to determine these characteristics accurately, conveniently, and quickly.
• 
  
• The PSI Tensile Testing Machines provide a relatively inexpensive way for determining the tensile strength and elongation of a variety of raw materials such as rubber, leather, fabric, plastics, belts, wires, and etcetera. They are based on constant rate of traverse principle, in which one end of the test specimen is held in a stationery grip while the other end is moved at a known fixed speed with the help of a motor, gearbox, and screw arrangement.
• 
  
• The load exerted on the stationary grip is measured by a load cell and is displayed on a digital indicator. The indicator has a peak force retention memory, which can be recalled to display the maximum load exerted on the test specimen before its failure. An overload protection relay is provided to automatically stop the motor if the load exerted goes above the maximum capacity of the load cell.
• The movement of the lower grip is indicated on a digital indicator with per-set arrangement to automatically stop the motor at any desired separation of grips.
  
• The speed of traverse of the lower grip is controlled using a frequency based invertor drive and can be changed with the help of six toggle switches to obtain seven traverse speeds. The speed can also be adjusted continuously with the help of a potentiometer. The speed is displayed indirectly as frequency being supplied to the motor by the invertor.
• The frame of the test is fabricated from heavy mild steel sections to give it the required rigidity and strength. Various built in safety arrangements such as over-load and over-travel protection, and automatically stopping of the motor on failure of the test specimen are provided.
  
• If desired, the tester can be provided with an arrangement to link it with a computer. Suitable software for calculation of the results and drawing of graph is also provided in such case.
• The tester is finished in grey hammertone stoving painting and bright chrome / zinc plating to give it a corrosion resistant finish. The tester is supplied complete with electricals, which include micro-switches, push buttons, and contactors for safe and convenient operation.
  
• A variety of grips suitable for holding different materials or for conducting different tests are available as optional accessories.
• Arrangement to plot load versus elongation graphs can be provided against specific requirement.
