Bi-00-702 Thermo Mechanical Test Systems simulate combined effects of thermal cycling and mechanical fatigue. These systems are useful for testing specimens subjected to synchronized heating, cooling and temperature compensated strain or force with optional expansion to simultaneous torsion or internal pressurization. These fully integrated test systems are available in the range of 50 to 500 kN force ratings and are ideally suited for aerospace and power generation industries.

The specimen under test is subjected to extreme temperatures followed by rapid cooling by means of a digitally controlled induction heater and pneumatic air directed on the specimen through air cooling nozzles.

Water cooled self locking and auto aligning hydraulic grips, high temperature extensometer, temperature sensors and load cell are typical components of the test system controlled by a 2370 series controller with synchronized data acquisition up to 5 kHz.
