Vibration ShakersModal and Inertial Exciters

Full range of modal and inertial shakers with integrated and easy-to-use amplifiers. Our permanent magnet shakers are compact, lightweight, and powerful general-purpose shakers that can be used for modal and vibration testing. They have a high DUT capacity despite their small sizes.

Vibration Shakers highlights

Lightweight, Durable, Portable

All our vibration shakers are built with extreme care and quality, are very durable, and small enough to be easily portable. The inertial shakers are easily mounted and have great mobility. 

Included Integrated Amplifier

Dewesoft vibration shakers and vibration exciters have integrated amplifiers. With this integrated amplifier, it is very easy to use the shaker. You only need to plug the electric cable and the shaker is ready to run. DS-MS-250 and DS-MS-440 come with a dedicated external amplifier.

Integrated Signal Generator

All shakers have integrated sine signal generators. This gives customers the option to try the test system or the shaker or make some simple test to understand structural behavior.

Superior Low-Frequency Performance

Offering optimal force performance over a wide frequency range – the inertial shaker IS series spans from 10 to 3,000 Hz.

Trunnion and Handles

All PM shakers have trunnion and handle allowing the shaker to be positioned in any orientation and position.

Integrated Screen

This feature can be used only with an integrated signal generator. It shows the frequency of the generated signal. By visualizing generated signal frequency it is possible to set the shaker to a certain frequency from 1 Hz to 15 kHz and even can see the behavior of the structure under excitation with a certain frequency.

Small Amplifier Box for Inertial Shakers

All inertial shakers are using the same amplifier box. This box is also capable of generating sinus signals and can be used for 3rd party shakers as well. The small, all-in-one box can be customized to generate different signals like white or pink noise or different forms.

Dewesoft quality and 7-year warranty

Enjoy our industry-leading 7-year warranty. Our data acquisition systems are made in Europe, utilizing only the highest build quality standards. We offer free and customer-focused technical support. Your investment into the Dewesoft solutions is protected for years ahead.

Permanent magnet shakers

Dewesoft permanent magnet shakers are compact, lightweight, and powerful general-purpose shakers that can be used for modal and vibration testing. They have high DUT capacity despite their small sizes. PM-20 and PM-100 have an integrated amplifier and a sine wave signal generator where the frequency can be adjusted from 1 Hz to 15,000Hz.

Advantages

  • Lightweight, durable, portable, and easy to use

  • An adjustable trunnion base provides a high degree of flexibility

  • Broad frequency range

  • Embedded power amplifier and signal generator for PM-20 and PM-100

Applications for permanent magnet shakers

Permanent Magnet shakers are used for Vibration testing and Shock testing:

  • Vibration testing of micro parts, assemblies, and electronics Modal testing

  • Shock testing

  • Sensor calibration

  • Separation and compacting of powders

  • Fatigue and resonance testing

  • Velocity transducer or high-speed actuator

  • Mechanical impedance measurement

  • Education and research

Inertial shakers

The shakers used in modal testing and in-flight tests of aircraft are usually electrodynamic shakers. However, the traditional shakers are not very portable and the attachment process takes time. Dewesoft inertial shakers are easily mounted and have great mobility. It can be used as a handheld.

Advantages

  • Compact and lightweight design

  • Superior low-frequency performance

  • Any angle mounting

  • Low friction bearing guided

Applications for inertial shakers

Inertial shakers are used for Vibration and Modal testing. Inertial shakers are used for testing car chassis, squeaks, and rattle testing in cars, civil engineering prototype testing, building structures, floor loading resonances, ships’ flight decks, and helicopters rotor simulation, submarines, geophysical surveys, and vibration cancellation systems.

Shaker amplifier included

All our vibration shakers come included with an amplifier out of the box.

MS-20 and MS-100 vibration shakers have integrated amplifiers. With this integrated amplifier, it is very easy to use the shaker. You only need to plug the electric cable and the shaker is ready to run.

DS-MS-250 and DS-MS-440 come with a dedicated external amplifier. Specifications can be found on the tech specs page.

Perfect data acquisition system companion

We offer very high dynamic data acquisition systems to accompany our vibration shakers and offer a total all-in-one tool for vibration testing and vibration analysis. We recommend SIRIUS modular data acquisition systems with analog outputs for the best combination.

Systems include direct IEPE sensor inputs with 160dB dynamic range. That's not all. Signal amplifiers are available for virtually any sensor or signal. TEDS IEEE 1451.4 technology makes sure that your TEDS sensors are connected, recognised, and configured in the software automatically.

Award-winning data acquisition software makes it easy to set up measurement under a minute. A software license is included in every system. Free lifetime software upgrades included. No yearly maintenance or upgrade fees, free online training courses.

Our data acquisition systems are modular and expandable. Can you imagine an FFT analyzer with thousands of channels? We can... Systems can be gradually expanded from one to an unlimited number.
