The one and three pound hammers are designed for exciting such structures as machinery, shafts, large beams, pipelines, storage tanks and other large structures. The 12-pound hammer can be used on larger structures including bridges, buildings, decks and floors. (read more)

Scaled modal models require a precise force measurement. This can be achieved by electrodynamic and servohydraulic exciters controlled by a signal generator via a power amplifier. A more convenient and economical excitation method is a hammer fitted with a high-quality piezoelectric force transducer. (read more)

Useful measurements of mode shapes on very light structures require excitation from a very low mass exciter with a high resonance frequency (300 kHz). These outstanding features are available with the Endevco 2301 mini modal hammer. The hammer structure features very high stiffness and low head mass (only 2 grams). (read more)
