Tension Measurement for Materials Testing.
More than thirty years of experience have been invested in the development of our products. At the Jackson, Wyoming facility, we design and build strain gauges for testing around the world.
Extensometers are available to test almost all engineering materials, including: elastomers, plastics, composites, metals, ceramics, geomaterials (eg, rock, concrete, and asphalt), and biomaterials such as bone.
There are models for small and delicate samples, ranging from relatively fine wire to massive metal samples and large rock cores.
The wide variety of models covers almost every type of test, as well as: Traction - Compression - Bending - Fracture Mechanics - Cyclic controlled stress tests such as low cycle fatigue.
Many of the extensometers are also capable of operating at a relatively high frequency. |
Axial Extensometers Model 3542. General purpose strain gauges for axial traction, compression, and cyclic testing. Meter lengths are 0.5 to 2 inches (10 to 80 mm) and measuring ranges from 5% to 100% strain. These extensometers are designed to test a wide range of materials including metals, plastics, composites, and ceramics. The double flex design makes it very resistant and insensitive to vibrations, allowing higher operating frequency. The quick coupling kit can be removed, allowing mounting of the extensometer with springs or elastic bands. Model 3542 extensometers are tension-assured devices, which ....

Bi-Axial or Axial Averaging Extensometers Model 3560
A single integral unit provides simultaneous lateral (transverse) stress and averaged axial stress measurement. The unit is also available as just an averaged axial extensometer. This extensometer is ideal for testing anisotropic materials such as advanced composites, as well as for general purpose tests such as determining the Poisson radius. The 3560BIA uses (there is an extra space between these two words) a unique Epsilon design, where the edges of the blades remain parallel during travel ...

Fracture Mechanics Clip-On Gages Model 3541
For fracture mechanics studies, these COD meters are in accordance with standard test methods, such as ASTM E1820 for the determination of fracture toughness properties of metallic materials. These meters conform to the requirements of E1820 (the replacement for the E813 and E1737) for JIC and R-curve determination. Special configurations are available to meet ASTM E399 requirements for fracture strength ...

COD High Temperature Model 3548
COD Meter Oven (1200 ° C or 1600 ° C) COD High Temperature Gauge for use on materials with a slot for ceramic bars. Water cooled and oven stand mounted, these are for use at 1200 ° C (2200 ° F). The high temperature option allows use at 1600 ° C (2900 ° F). They are specifically designed for mechanical fracture tests. These COD meters mounted on a water cooled rack, which is mounted on a side cut oven with a load cell option for the rack ...
