Digital Tensile Testing Instrument

Product description of digital tensile testing machine 

Digital tensile testing machine had a long electronics and a chart recorder. They have been replaced by digital controls and PC software. The new controls automatically run the test and display the data-sometimes even while the test is going on. In the the old days of chart recorders, and even in the early digital era before PCs, all the user obtained from the test were load/deformation curves representing force on the y-axis versus deformation on the x-axis. These curves required calculation and interpretation. The newest systems still provide these curves, but they also calculate the desired data such as yield and failure strength and modulus. The most common tests performed on plastics with a UTM are tensile strength and modulus and flexural strength and modulus. For tensile testing by ASTM D638 and ISO 527, the sample is clamped at both ends. One clamp is stationary and the other is in a crosshead that moves away from the fixed clamp, pulling on the sample until it breaks, after which the crosshead automatically halts.
