Model 632.65 High Temp Clip-On Displacement Gage

Common Features

• High-temperature clip-on displacement gages for fracture mechanics testing up to 1200°C (2200°F)
• Designed for KIC, JIC, and crack growth testing applications
• Replaceable extension rods minimize creep, thermal expansion error, and conduction losses
• Meet or exceed ISO 9513 Class 0.5 calibration requirements
• Seamless integration with MTS systems, including MTS 652 furnaces

Model-Specific Features

632.65X-03

• Optimized for front face contact on CT specimens
• Higher seating force maintains secure knife-edge engagement throughout the test
• Ideal for KIC testing where stable attachment and reliable displacement measurement are critical

632.65X-04

• Uses alumina rods; supports both front face and load line configurations on CT specimens
• Reaches the load line directly — ideal for JIC and J-based fracture mechanics methods
• Minimum gage length: 5 mm (0.2 in.)
