The Z602WA impedance head is a cylindrical structure containing a piezoelectric accelerometer and a piezoelectric force gage. This transducer can be used to measure applied force and structure motion. From these measurements mechanical impedance can be obtained. The high impedance charge signals from the piezoelectric force gage and accelerometer are internally amplified using the PiezoFET® low noise charge amplifier. Each amplifier requires a constant current DC supply.
The Z602WA has a specimen contact diameter of 0.56 inches preventing excessive stiffening by impedance head attachment. The very low mass below the force gage (20 grams) makes it possible to take measurements on relatively light structures, such as airframes, models and light machinery.
