Impedance Head

The KEMO VTIH10 Impedance Head is a sophisticated combination sensor designed for simultaneous measurement of force and acceleration during vibration testing and modal analysis experiments. This integrated transducer assembly features coaxial arrangement of force sensor and accelerometer in a single housing, ensuring accurate measurement of the force-to-acceleration ratio defining mechanical impedance. The impedance head enables direct frequency response function measurement, accurate modal testing without requiring separate force and motion sensors, and minimized phase errors through collocated sensing. It incorporates appropriate sensitivity balance between force and acceleration channels, threaded mounting for secure attachment, and ICP signal conditioning for simplified integration. This essential modal testing instrumentation provides accurate input-output measurement for experimental transfer function determination, supporting structural dynamics research, vibration analysis, and modal parameter extraction in applications requiring precise characterization of dynamic mechanical properties and frequency response characteristics.
