The型号3442RA1微型平均轴向延伸计from Epsilon are strain gaged devices used for performing tensile or compressive strength tests on concrete, small rocks, and other small compression samples.
Using the model 3442RA1 extensometer, axial strain measurement is performed on the opposite sides of the test specimen. The average of two readings provides the output. The extensometer comes in different gauge lengths ranging from 25 to 50mm, and measuring ranges from 1.2 to 2.5mm for samples with 50mm or even smaller diameter.
Themodel 3442RA1可以轻松地安装并在测试样本上自支撑。它具有由碳化钨制成的圆锥点接触。根据要求，可以单独配置这两个切口以提供两个读数。Epsilon为机油应用提供了不同的版本，涉及在400°F时运行压力为20,000PSI。
The型号3442RA1伸展计are suitable for small inside diameter vessels, while the Model 3542RA averaging axial extensometers are recommended for large diameter specimens.
The model 3442RA1 extensometers can be used along with any electronics developed for strain gaged transducers. They are joined to a test machine controller, which includes the signal conditioning electronics designed for the extensometer.
Using the proper connector and wiring, the electronics can be directly linked to the extensometer. The system without the desired electronics makes use of Epsilon's different solutions to connect the output to the chart recorders, data acquisition boards, or other devices.
