What are the differences in the configuration of electronic extensometers for testing machines?

          Li Ling Testing Machine Company is a manufacturer of electronic universal testing machines, hydraulic universal testing machines, pressure testing machines, impact testing machines, steel strand special testing machines, fatigue testing machines, anchoring testing machines, friction and wear testing machines, and steel bar bending testing machines. We strictly control the selection of main accessories to ensure the stability and practicality of the testing machines! Today, we will mainly talk about the electronic extension meter used on the testing machine.

          Electronic extensometer is a sensor for measuring the deformation of test specimens under stress, while strain gauge extensometers are widely used due to their simple principle and easy installation. Electronic extensometers can be divided into axial extensometers, transverse extensometers, and clamp extensometers according to the measurement object.

          What are the specific differences in the configuration of electronic extension meters? 1. 0.5 level and 1 level precision testing machines, equipped with electronic extensometers for 0.5 level and 1 level respectively; The indication errors are ± 0.5% and ± 1%, respectively. 2. Fully automatic or non-contact extensometers are mainly used to measure the mechanical properties of extremely brittle materials (such as HT) and the Poisson's ratio u of metal sheets
