Modal Exciters

Core competences and comprehensive range of products and solutions to help customers solve vibration challenges. B&K offers the following Modal Exciters:

  • Type 4824

    A compact and lightweight modal exciter with a force rating of 100 N (22 lbf), Type 4824 is ideal for high-precision, single- or multi-point excitation of a range of payloads, from automotive powertrain and drivetrain components to large and very large structures.

  • Types 4825 and 4826

    With force ratings up to 200 N (45 lbf) for Type 4825 and 400 N (90 lbf) for Type 4826, these exciters are ideal where payloads require high-precision excitation in single- or multi-point setups. Strong and versatile, they are used for a variety of applications, such as testing of engines, body-in-white on passenger cars and small trucks, and aerospace structures.

  • Types 4827 and 4828

    Designed for the most demanding experimental modal testing applications, these exciters have force ratings up to 650 N (146 lbf) for Type 4827 and 1000 N (225 lbf) for Type 4828. They are ideal for high-precision, single- and multiple-point excitation of extra-large devices, such as locomotives, industrial turbines, heavy-duty pumps and aerospace assemblies.

  • Type 1056

    Designed to work as part of a system with our modal exciters and matching amplifiers, this unit enhances operation by correcting the position of the exciter’s armature or by applying pre-tensioning force to tension- or piano-wire stingers.
