An impedance head is a transducer consisting of two sensing elements: a force gage, which references the force acting between the shaker input connection and the test item connection, while the accelerometer senses the acceleration on the shaker face. Wilcoxon’s electromagnetic shaker systems include a built-in impedance head.
- Low frequency applications
- Integral impedance heads measure acceleration and force
- No matching network required
- Can be combined with piezoelectric shakers for wider operational bandwidth
