Because your applications deserve individual measurement solutions

With VibroFlex, Polytec introduces the new flexibility in optical vibration measurement with a modular sensor solution that adapts to your needs: Add microscope objectives for observing tiny structures or measure NVH noise vibration harshness on large, complex samples like machinery, motors etc. Discover acoustics and vibration phenomena in research and product development for a faster time-to-market or reliably and cost-efficiently inspect production parts in-line.

Modular vibrometer systems offer both outstanding signal quality and maximum flexibility. They are made up of a sensor head and a controller that you can combine as required. You can therefore flexibly adapt your vibration measurement system to suit your individual measuring tasks and expand it as and when required.

The Industrial Vibration Sensor is key to fast and non-contact vibro-acoustic quality inspection, structure-borne noise analysis and reliable pass-fail decisions. Its robust and compact design means you can optimally integrate it into process control systems and production environments with very short cycle times. The vibrometer is wear-free and saves you from using expensive servo-mechanisms or noise protection cabins.

The flexible vibration-measuring device with an integrated camera and a compact design is ideal for quality assurance and research. Additional microscope lenses expand the range of possible tasks that you can complete to include very small samples.

Portable, robust and battery-powered, the PDV is the ideal measuring device if you want to be mobile – when carrying out condition monitoring operations on machines and systems, for example. Also available as an educational kit with exciting experiments for training purposes.

The PSV Scanning Vibrometer measures vibrations on an entire surface in a non-contact and laser precise way. This flexible measurement platform allows researchers and developers to master the most challenging vibration measurement tasks with ease. Upgrade or expand it to a full 3D system, once your application-specific demands grow. Detect and visualize operational deflection shapes and Eigen modes with this cutting-edge laser Doppler vibrometer.

PSV-3D Scanning Vibrometers measure 3D dynamics in research and product development in a reliable and precise way. The deflection shapes and Eigen modes detected help you with everything from NVH, acoustic and structurally dynamic issues to ultrasonic analyses, FEM validation and non-destructive testing.

48 eyes see more than one. The multipoint vibrometer opens up completely new vibration analysis possibilities for you – even for transient processes and on surfaces where tactile measurement methods reach their limits. The laser-based MPV-800 describes deflection shapes as a function of frequency and – for the first time ever – time too.

By combining a 3D scanning vibrometer and an industrial robot, RoboVib® offers you an automated measuring station for measuring everything from complex components to complete vehicle bodies. Both the amount of time required and the sources of error – especially in experimental modal analysis – are reduced significantly. So you can thoroughly test a vehicle body, for example, in just one to two days, whereas you would previously have needed weeks to even prepare for the test itself.

You use the entry-level device for microscope vibrometry to record vibrations on small components and microsystems with a high degree of precision over the entire surface. The device works contactlessly and therefore measures the dynamics of even small samples in a completely undistorted way.

You can use the UHF Ultra High Frequency Vibrometer to analyze out-of-plane vibrations up to 2.4 GHz for comprehensive analysis of transient events in real-time.

The all-in-one optical measurement solution for static and dynamic 3D characterization of MEMS and microstructures. The MSA-600 advances development and QC processes - and integrated into commercially available probe stations it even allows testing on wafer-level.

The 3D Micro System Analyzer records vibration components in all three spatial directions at once. The optical measurement system enables high-resolution 3D vibration analysis with amplitude resolutions in the sub-picometer range, for both in-plane and out-of-plane vibration components.

The HSV-100 High Speed Vibrometer allows you to simultaneously measure displacements and vibrational velocities up to 40 m/s. To measure the valve train dynamics, the system can be expanded to include as many channels as you like and allows you to compensate for the test bench’s vibrations.

You can use the IPV-100 In-Plane Vibrometer to perform non-contact and non-invasive vibration and movement measurements perpendicular to the measurement axis (e.g. stroke movements of pistons, valve shafts and tools) or highly dynamic strain measurements.

The RSV-150 Remote Sensing Vibrometer performs high-precision measurements from a safe distance: Now you can use the RSV-150 Remote Sensing Vibrometer to quickly and easily measure vibrations and displacements on structures and machines. All you have to do is point, shoot and measure, and with sub-micrometer resolution, even at a distance of several hundred meters. Also suitable for drop and shock tests up to 24 m/s and frequencies up to the MHz range

The RLV-5500 Rotational Laser Vibrometer measures the angular velocity and angular displacement of rotational vibrations on any shape of rotating structure. It precisely analyzes the rotational dynamics of drivetrains, gas turbines, electrical generators, printers and copiers, and thus enables you to develop products efficiently and quickly perform troubleshooting operations.

The package of Strain Processor in combination with a PSV-3D Scanning Vibrometers allow a non-contact, optical measuring alternative for dynamic stress and strain distribution and Finite Element model updates.

PolyWave - the scalable software package for comprehensive analysis of vibration test data offers a seamless post-processing, making your vibration analysis with Polytec laser Doppler vibrometers more efficient than ever.

The convenient way of sharing your scanning vibrometer measurement data with your colleagues and project partners. The file viewing software does not require a licence for the measurement software so that everyone involved is always provided with the latest data and evaluations.

Multi-channel, PC-based testing software for fully or partially automatic process monitoring and quality control. The diagnostics package includes both software and hardware for evaluating the various vibration sensors’ measurement signals to enable control of the test process, and communicating with the production control system.

The DLL software library enables external programs (such as Visual Basic, Matlab, LMS Test.Lab, VSI Rotate) that support the Microsoft® Standard Component Object Model (COM) to access information and data included in Polytec’s measurement files.

The data acquisition software for single-point and special-application vibrometers additionally controls all the vibrometer settings via the RS-232 or USB interface. Integrated signal enhancement, the optional function generator for arbitrary excitation signals and real-time video imaging of the test object under examination provide you with practical support in your daily work routine.
