概述
The Dytran 5800B2 is a general purpose IEPE impulse hammer used to excite structures or machinery with a definable impulse force. 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. Available with a 50 lbf range, the Dytran model 5800B2 features a 100-gram head weight and is supplied with three interchangeable impact tips.
The Dytran Dynapulse™ impulse hammers incorporate a special acceleration compensated piezoelectric force sensor in the hammer head at the striking face, ensuring a smooth frequency spectrum that is free from anomalies. Electrical connection is achieved via a BNC connector jack located at the end of the hammer handle.
