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 700 °C (1300 °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 transverse strain 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. Together, these extensometers are suitable for high temperature measurement of Poisson’s ratio per ASTM E132 with most materials and specimens.
The 7675 is supplied with the advanced DT6229 controller. The standard output is 0-10VDC analog signal, factory calibrated with the extensometer. This system provides a number of functional enhancements, including high speed digital output, built in calibration and tare functions, analog and digital filters, and more.
