This innovative high temperature extensometer has been developed for testing ceramics, metals and composites at high temperatures produced by induction heating systems and furnaces. A number of features together render these extensometers convenient for use and enables higher performance than other similar high temperature extensometers.
The units are positioned on the specimen by flexible, light ceramic fiber cords. These render the extensometer self-supporting on the specimen. There is no need for any furnace brackets. The side load on the test sample is considerably reduced due to the light weight and self-supporting design of the sensor.
