General Purpose Impact Hammer MIH-20

This general purpose IEPE Impact Hammer, large, heavy structures with a definable impulse pulse measuring up to 20,000 N.  Therefore, allowing the studying of dynamic impact behaviour and determining the overall structural health of a test specimen.

Applications for this product include:

  • Impact force measurements large, heavy structures
  • Propellors
  • Large Civil Engineering Structures


Used in a dynamic structural testing system for modal analysis.

The MIH-20 Model is a General Purpose Impact Hammer for large and heavy structures or machinery. It is part of our MIH Impact Hammer Series product range.

The purpose of an impact hammer is to measure the frequency response functions using impact excitation techniques.  A tool commonly used as part of a dynamic structural testing system.  Especially, modal analysis in the prediction of a structural response of items.

Firstly, the MIH-20 has a measurement range of ±20,000 N. In addition, with a 0.25 mV/N output sensitivity.

Secondly, a great feature of MIH series hammers is that it incorporates quartz dynamic force sensor built into the impact hammer tip. Coupled with inbuilt electronics, along with a reduced size and weight of the hammer head and ergonomic handle it reduces the overall hammer inertia.  Providing a quicker rebound and a high frequency excitation to be produced.

Electrical connection is achieved via a BNC Connector located at the end of the hammer handle.

Finally, this product is supplied with casing, a 2 Metre Coaxial Cable, and 3 interchangeable head tips.  The head tips range are hard, medium and small.  Perfect for determining the impulse shape and the bandwidth of the excitation.
