In the instrumented Class H-4 version, the striker is built with an integrated force transducer that measures the impact force throughout the entire strike instead of recording only the final absorbed-energy value. When the pendulum hits the sample, the sensor captures force at high speed and sends the signal to the controller and PC software. The system then builds a detailed force–time or force–displacement curve showing how the material reacts at every stage of the fracture.

The transducer detects the initial elastic response, the start of crack formation, the peak load, crack growth, and the point where the specimen fully breaks. Because the sensor collects data continuously, the operator can see subtle events that a traditional Charpy tester would never record.

This setup is especially valuable for comparing materials, assessing brittle vs ductile behavior, or validating heat treatments. It gives engineers far deeper insight than a single energy value and turns the impact test into a full dynamic-fracture analysis tool.
