The PSV-400 Scanning Vibrometer comprises both state-of-the-art hardware and software. It includes a compact sensor head with an integrated scanning unit, a vibrometer controller and a data acquisition and management system. These components are complimented by a powerful software package that controls the scanners, data processing, and visualization of the measurement results.

Carrying Out a Measurement from Start to Finish

The PSV-400 is easy and intuitive to operate, especially when compared with traditional multipoint vibration measurement methods requiring time-consuming preparation of the test object and sensors. To setup the system, define the geometry and scan grid, and measure. The vibrometer automatically moves to each point on the scan grid, measures the response and validates the measurement by checking the signal-to-noise. When the scan is complete, choose the appropriate frequencies and then display and animate the deflection shape in several convenient 2-D and 3-D presentation modes. These on-screen displays are extremely effective tools for understanding the details of the structural vibration.

A High-Precision Optical Transducer

At the heart of every Polytec PSV-400 system is the laser Doppler vibrometer – a very precise optical transducer used for determining the vibration velocity and displacement at a point by sensing the frequency shift of back scattered light from a moving surface.

The PSV-400 Scanning Vibrometer is a powerful data acquisition platform that can seamlessly integrate into the engineering workflow and the IT environment. The system provides input interfaces for geometry data from CAE and FEM packages or from the convenient Geometry Scan Unit. All measurement resultsare available to third party applications through various export filters and PolyFileAccess, an open data interface. A powerful post processor is integrated in the PSV Software to apply various mathematical operations to the measured data. External software packages can control the PSV remotely by using an integrated VisualBasic® compatible scripting engine.

The PSV-400 Scanning Vibrometer is used to study objects of very different sizes including large automobile bodies, airplane fuselages, ship engines and buildings as well as tiny silicon micromachines, hard disk drive components and wirebonders. Demanding applications such as measurements on hot running exhausts, rotating surfaces, underwater objects, delicate structures or ultrasonic devices are all made possible by the PSV-400.   More information about Vibrometer applications >>
