The 3548COD gages accurate strain gaged devices mounted on a water-cooled bracket, which is mounted on the furnace cut-out, or with optional load frame support brackets. Additionally, high purity alumina rods are supplied with the standard temperature version (to 1200 °C). The high temperature option is furnished with alpha grade silicon carbide rods. The rods are made to order to the length needed for
the specific furnace. For best performance with this model, contact edges on the test sample should be somewhat rounded (not sharp knife edges).

The application range includes:
Fracture Mechanics Testing to international standards as ASTM E1820, E399, E647 etc
Standard Units meet ASTM E1820 requirements for accuracy

Features

• Full bridge, 350 ohm strain gaged design for compatibility with nearly any test system.

• All standard units meet existing ASTM E1820 requirements for accuracy.

• All units come with either high purity alumina ceramic rods (1200 °C) or alpha grade silicon carbide rods (1600 °C).

• Rugged, dual flexure design for strength and improved performance.

• Includes high quality foam lined case and a spare set of ceramic rods.

Important Note
Liquid cooling is recommended for all elevated temperature tests to obtain the best measurement accuracy and retain the validity of a room
temperature calibration when the specimen temperature is >540 °C (1000 °F).
Cooling is necessary to prevent extensometer damage for testing in the range of ~800-1600 °C (1500-2900 °F).
