概述
The Dytran 5850B 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. The model 5850B features a 3-position toggle switch located on the hammer handle, which allows the user to select from 3 different sensitivities for use with test objects of varying size. Larger testing structures require higher force levels for adequate excitation while tiny structures require much lower force levels. Thus, a wide range of sizes of objects or structures can be tested with this versatile hammer. Sensitivities available are 1, 10 and 100 mV/lbf. The Dytran model 5850B features a 150 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.
