The PDV-100 Portable Digital Vibrometer is the first portable, battery-powered digital vibrometer for field studies that enables you to easily and precisely monitor the condition of machines, for example. The PDV-100 contactlessly measures vibrational velocities in the 0 to 22 kHz frequency range and provides digital signal processing with both analog and digital signal outputs. Its lightweight, robust design in a hermetically sealed housing makes this device a handy and practical tool, whether used as a battery-powered solution or together with a mains adapter.
The Polytec’s CLV-2534 Compact Laser Vibrometer consists of a controller in a 19” rack housing which is connected to the compact sensor head (protection class: IP64) via a fiber-optic cable. It is therefore ideal for industrial purposes. A wide range of options – such as an integrated video camera, an integrator for displacement measurements or a variety of microscope lenses – make the CLV-2534 the ideal tool for development and production applications in the automotive or electronics industry, for example. The down to 1.5 µm small spot allows you to perform measurements on small structures under direct visual control, so there’s no need for an extra microscope. As it has a high level of optical sensitivity, the compact laser vibrometer is perfectly suited to both challenging testing and development tasks in the laboratory and quality control operations in harsh industrial environments.
The new IVS-500 Industrial Vibration Sensor is the key to fast acoustic quality inspection, structure-borne noise analysis and reliable pass-fail decisions. This Laser sensor measures reliably, in demanding industrial environments, without contact and therefore without wear and on virtually all surfaces. Costs and yields are therefore optimized by reducing false rejects in the production and assembly process.
The flexible setup of the OFV-5000 Modular Vibrometer allows for customer- and application-specific configurations. Choose from different sensor heads to best suit your specific measuring task and configure the decoders regarding the required vibrational displacement, velocities and acceleration.
The OFV-5000 controller is the core of the modular vibrometer. It decodes the sensor head’s signals in real time. To this end, you can choose from a wide selection of high-performance vibration displacement, acceleration and vibrational velocity decoders that cover the frequency range from DC to 24 MHz, vibrational velocities up to ±25 m/s and displacement resolutions down to 0.1 pm.

With PSV Scanning Vibrometers, you can reliably and precisely complete your vibration measurement tasks in research and product development. 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.
Polytec 3D Scanning Vibrometers (PSV-3D) complete your vibration measurement tasks 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.
The PSV-3D conducts precise full-field measurements of the crosstalk between sensor elements, the propagation of surface waves in non-destructive materials testing or the development of integrated sensor networks for composite materials. It uses the data in both the time and the frequency domain to supply you with easily understandable images and animations.
With the laser-based MPV-800 Multipoint Vibrometer from Polytec, you can carry out time-synchronous measurements with up to 48 channels and represent both frequency-dependent and time-dependent deflection shapes. The fiber-optic sensor heads are freely configurable and allow you to perform flexible measurements – both parallel to a surface or arranged individually around the sample you’re using to record all the measurement values.
The RoboVib® Structural Test Station combines a 3D Scanning Vibrometer with an industrial robot – to create a productive vibration analysis solution. The automated measuring station automatically tests everything from complex components to entire vehicle bodies. Both the amount of time required and the sources of error in experimental modal analysis are reduced significantly. So youYou can therefore 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 can use Polytec’s MSA-050 Micro System Analyzer 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. The tried-and-tested and continuously optimized Polytec scanning vibrometer software makes operating the instrument child’s play and allows the user to create clear animations of the measuring results.
The UHF-120 Ultra High Frequency Vibrometer is characterized by a significantly extended measurement bandwidth – enabling high-resolution and full-field analysis of out-of-plane vibration frequencies measuring up to 2.4 GHz. The UHF-120’s high lateral resolution of less than 1 µm is decisive particularly for visualizing the surface waves of SAW (surface acoustic wave) components. Another application involves validating the behaviour of BAW (bulk acoustic wave) components and imaging ultrasonic transducers that work in the ultra high frequency range.
Surface topography and dynamic motion analysis and visualization are key to testing and developing microstructures such as MEMS devices (Micro-Electro-Mechanical Systems). They are indispensable for validating FE calculations, determining cross-talk effects and measuring surface deformation.
Real objects’ vibrations are usually three-dimensional. While you can indeed show preferential directions, production tolerances and other influences lead to movement components in other spatial directions too. You can use the MSA-100-3D Micro System Analyzer to analyze your sample’s dynamic behaviour in an integrated way, over a wide bandwidth and in real time. The vibration components in all three spatial directions are recorded simultaneously in high resolution and are analyzed as an integrated data record. You achieve the sub-picometer amplitude resolution typical of laser vibrometers regardless of the direction of vibration.
The HSV-100 High Speed Vibrometer allows you to simultaneously measure displacements and vibrational velocities up to 40 m/s. You can configure a multi-channel system for your application with the precise, synchronized electronic units to; for example, compare valve elevation curves with the desired value at different speeds on the motor test bench. At the same time you can investigate phenomena such as valve bounce in the kilohertz range or the timing between cylinders. The digital decoders in the HSV-100 provide you with low-noise and therefore unambiguous results and can compensate for the test bench’s vibrations.
The Polytec IPV-100 In-Plane Vibrometer allows you to perform non-contact vibration and movement measurements perpendicular to the measurement axis – ideal if the measurement point is only accessible from the side. You can thus measure the stroke movements of pistons, valve shafts and tools, for example, or perform highly dynamic strain measurements.The Polytec IPV-100 In-Plane Vibrometer allows you to perform non-contact vibration and movement measurements perpendicular to the measurement axis – ideal if the measurement point is only accessible from the side.

With the Polytec RSV-150 Remote Sensing Vibrometer, you can now quickly and easily measure vibrations and displacements on structures and machines, even from large distances. All you have to do is point, shoot and measure! The robust RSV-150 was specifically developed for mobile outdoor use for the purpose of condition monitoring and checking the dynamics of structures and systems.
With the Polytec RLV-5500 Rotational Vibrometer, you can conduct non-contact measurements of the angular velocity and angular displacement of rotational vibrations on any shape of rotating structure. The RLV-5500 helps you to precisely analyze the rotational dynamics of drivetrains, gas turbines, electrical generators, printers and copiers, and thus enables you to develop products efficiently, and perform troubleshooting operations quickly. The process is precise, contactless and therefore requires no additional masses or mechanical intervention in the drive.
