Impact Hammer

Impact Hammer Kit

OverviewThe Impact Hammer Kit is used with our ADRE® 408 DSPi and other compatible instruments to determine the transfer function and other response characteristics of rotating machines and other mechanical structures. The integration of response information from multiple accelerometers at various points of interest allows for modal analysis (velocity compliance, impedance, mobility). The hammer is available in a variety of sensitivities and masses. It can be purchased as a complete kit with carrying case, connection cables, a variety of hammer tip accessories, and optional structural accelerometers. It can also be purchased separately from the accessories found in the kit version.
