The Exciter Head, with its force and displacement transducers, generates and measures the force or torque to the structure being tested and provides feedback signals for control of the test variables.
Exciter heads are designed for maximum problem-solving flexibility in applications, fixtures and operation. Available in a broad range of force/ torque capabilities in linear, torsional, and inertial mass models, the exciter heads provide controlled static and dynamic force for a wide range of structural testing applications.
