Designed for transverse or diametral strain measurement in environmental chambers where the entire extensometer must be exposed to elevated temperatures. These capacitive extensometers may be used up to 600 °C (1100 °F) without any cooling.
These transverse extensometers use a high-temperature capacitive sensor and do not require any cooling. They will operate up to the maximum temperature limit of most environmental chambers used in materials testing. The Model 7675 is ideal for determination of Poisson's ratio, and for characterization of anisotropic materials such as composites. All units can accommodate both positive and negative displacements. Model 7675 transverse extensometers are compatible with most Model 7642 high-temperature axial extensometers.
