The Dytran model 5803A is an IEPE impulse sledge hammer, used to excite larger structures with a definable impulse force, for purposes of studying their dynamic behavior. The impulse is used to identify resonances, an important measurement parameter for the study of dynamic behavior, as well as to help determine the overall structural health of a test specimen.

With a sensitivity of 1 mV/lbf and an available measurement range of 5,000 lbf, model 5803A is the largest of the Dytran sledge hammers with a head weight of 12 pounds, and is supplied with four interchangeable impact tips. Electrical connection is achieved via a BNC jack located at the end of the hammer handle. Design of the Dytran IEPE impulse sledge hammer incorporates a special acceleration compensated piezoelectric force sensors in the hammer head at the striking face, ensuring a smooth frequency spectrum that is free from anomalies.
