Introduction: In some departments, it is necessary to measure the mechanical properties of rubber, plastic and other materials, and to measure the more accurate elongation, and it is hoped that the extensometer can measure the whole process of pulling off the specimen. Elongation is several times the gauge length. In this paper, a large range of extensometer used to measure the whole process of rubber and plastic drawing more accurately, draw the load-deformation curve, the maximum load and elongation. If the load and deformation signal to the computer, can automatically print the tensile curve and test reports. Set the extensometer on the testing machine platform, adjust the base screw, observe the level indicator blisters position, so that the extensometer perpendicular to the platform. Up and down the two slide along the rails can slide freely. Extensions arm mounted on the slide tube. The extensometer gauge can be adjusted by adjusting the distance between the upper and lower arms (the adjustment range is 25 ~ 200mm) when the upper and lower sliders are closed. The protruding length of the protruding arm is adjusted according to the distance between the guide rail and the sample. The front end of the telescopic arm is equipped with a chuck (as shown in FIG. 2), which clamps the rubber or plastic sample with a chuck. Tensile specimen elongation, up and down the slide seat tube spacing increases, the slide down the seat tube along the rail displacement through the photoelectric encoder, converted into electrical signal output, the digital display directly read the elongation. Technical Parameters: Standard distance: 25 ~ 200mm; Range: 0 ~ 500mm; Resolution: 0.2mm Travel 800mm; Power supply: 5VDC; Output: pulse; Accuracy: 1%; Sliding tube sliding resistance is less than 0.2N; Clamping force on the specimen: 10 ~ 20N; Specimen width range: 10 ~ 20mm Specimen thickness range: 2 ~ 10mm Size: 1250 × 230 × 150mm3;
