Tensile testing is an important test used to determine the best type of material for a particular application. For this test the material is molded to a standardized sample type and loaded into the machine’s grips. The sample is pulled apart by the machine until the tension causes the material to break or be deformed. Tensile testing can give important measurements such as the ultimate tensile strength (the maximum amount of strength a material can take) and the amount of elongation that occurs before breaking. Things to consider before purchasing tensile testing equipment include the type of grip which will dictate the sample shape, the speed range, the machine’s capacity, and what types of material the machine is optimized for.
The tensile tester is measured by a deformation measuring device, which is used to measure the deformation of the specimen during the test.
The device has two chucks connected to the photoelectric encoder mounted on the top of the measuring device through a series of transmission mechanisms. When the distance between the two chucks changes, the axis of the photoelectric encoder is rotated, the photoelectric encoder There will be a pulse signal output. And then by the microcontroller to deal with this signal, you can get the deformation of the sample.
