Axial extensometer
1.2 - 2.5 mm | MODEL 3442RA1
Epsilon Technology
2.5 mm), the Model 3442RA1 was designed for applications where tensile or compressive strength tests on small rock, concrete and other small compression samples is desired.
Axial strain is measured on opposite sides of the test specimen and the output is an average of the two readings. The Model 3442RA1 is available in a variety of configurations for samples 2 inches (50 mm) or smaller in diameter. All are self-supporting on the specimen and mount very easily. The included conical point contacts are made from tungsten carbide. If desired, the two cut-outs can be independently configured, providing two readings. Epsilon has versions for use in oil to 20,000 psi at 400 °F (1360 bar at 200 °C). These units will fit in small inside diameter vessels. For large diameter specimens, we suggest one of the Model 3542RA averaging axial extensometers.
