High temperature extensometers

3448

MODEL 3448 High Temperature Extensometers
This model is to be used at specimen temperatures up to 1200 °C (2200 °F) without any cooling. It is developed this unique high temperature extensometer for testing metals, ceramics, and composites at the high temperatures produced by furnaces and induction heating systems. The units are held on the specimen by light, flexible ceramic fiber cords. Large selection of options fits to the majority of the test applications.

MODEL 3648 High Temperature, Low Strain Capacitive Extensometers
This model was designed for low strain applications for use with split type materials testing furnaces or induction heaters. It features very low specimen contact force and includes a slide bracket for mounting. Water cooling allows use to 1200°C (2200°F) standard or 1600°C (2900°F) with the high temperature option.

3555

MODEL 3555 High Temperature Un-Cooled Extensometers
For use in environmental chambers where the entire Extensometer must be exposed to elevated temperatures. These capacitive extensometers may be used up to 540 °C (1000 °F) without any cooling.

MODEL 3580 High Temperature Diametral Extensometers
For transverse or diametral strain measurements at temperatures to 1000 °C (1832 °F). These Extensometers may be used with furnaces having a side entry slot for an extensometer or with induction heating systems. They utilize a proprietary, rugged dual flexure design.

MODEL 3675 High Temperature Transverse Extensometers
For tests in environmental chambers where the entire Extensometer must be exposed to the heat. Designed for transverse or diametral strain measurement at temperatures up to 540 °C (1000 °F) without any cooling. The 3675 Extensometer may be used simultaneously with the Model 3555 Axial Extensometer.

3548COD

MODEL 3548COD High Temperature Furnace COD Gages
High temperature COD gages for use in split type materials testing furnaces with a slot for the ceramic rods. Water-cooled and furnace bracket mounted, these Extensometers are for use to 1200 °C (2200 °F). The high temperature option allows use to 1600 °C (2900 °F). They are specifically designed for fracture mechanics testing.

3641
Designed for fracture mechanics tests in environmental chambers where the entire gage must be exposed to the heat. These capacitive sensor based clip-on gages (or COD gages) may be used up to 540 °C (1000 °F) without any cooling.
