PSV-400 Scanning Vibrometer
Non-contact Vibration Measurement, Vizualization and Analysis
The PSV-400 Vibrometer is a cutting edge measurement tool for non-contact measurement, visualization and analysis of structural vibrations. It determines the operational deflection shapes and Eigen modes as easily as taking a photograph. Entire surfaces can be scanned and probed automatically using flexible and interactive measurement grids. Measurements can be made over a wide frequency bandwidth. The PSV-400 offers technical excellence with powerful software for dynamic measurement, analysis and real-time chromatic display of data. Designed for resolving noise and vibration issues in R&D and manufacturing, the system is versatile and easy to use.

PSV-A-408 Extension to 8 channels
Extend the number of acquisition channels of the PSV-400-H4 systems from four to eight channels featuring an IEPE (ICP®) sensor power supply. The package comprises the software module, junction box extension (19”, rack-mountable), additional data acquisition board and all necessary connection cables. Together with the "Principal Component Analysis" software option for PSVsoft it enables MIMO modal analysis measurements by measuring the signals from excitation force sensors and driving point sensors.
PSV-A-410 Close-up Unit
For the measurement of small parts (³ 1mm x 1mm) and for measurements in close, Polytec offers the PSV-I-400 scan unit. Equipped with either a 99.8 % or 97 % splitter. Includes a set of close-up lenses for video (1, 2 and 4 diopters) and a HE-NE block filter.
Options: PSV-A-CL-80, PSV-A-CL-150 and PSV-A-CL-300 Lenses with fixed 80 mm, 150 mm, and 300 mm stand-off distance, respectively.
Allows for measurements on small samples like hard disk sliders, read-write heads or ultrasonic actuators
PSV-A-T11 Pan/Tilt Head
Motorized pan/tilt head mounted on a heavy duty tripod. If ordered with PSV-400-X it replaces the VIB-A-T02 standard tripod. Control of the pan/tilt position is achieved via buttons on the PSV-E-400 junction box or via software. Pan/tilt speed is 6 °/sec.
US Version: PSV-A-T11-US for use with heavy duty tripod model VIB-A-T03. The tripod is not included in this item.
PSV-A-T18 Vertical Test Stand
For translational positioning of the PSV-I-400 scan head when measuring small objects (e.g. HDD, DVD, etc.). Consists of a motorized three-stage telescope positioner, 90°-bracket for mounting PSV-I-400 scan head, drive electronics and control keypad, and base plate with metric and imperial hole patterns for mounting on standard optical tables. The microprocessor- controlled drive electronics allow positioning at three different speeds. The available positioning range of 300 mm covers all possible optical set-ups of the PSV-A-410 Close-Up Unit.
PSV-A-CL-xx Front lenses
Lenses for coaxial attachment to the PSV-A-410 for the measurements of very small parts or mirror-like surfaces.
Available for stand-off distances of 80mm, 150mm and 300mm.
PSV-A-010 System Cabinet 19"
PSV-A-MIR / PSV-A-MIR+ Mirror Set
Mirror set for measurements in difficult-to-access areas. The mirror set comprises 4 (PSV-A-MIR+: 5) high-quality coated mirrors plus magnetic base holders.
PSV-A-PDA Remote Control Unit
An optional PDA-based wireless control is available for added setup convenience, e.g. for accurate targeting of alignment and reference points. A PDA (mobile handheld computer) can be used to remotely control the PDA thereby supports the same functions as the handset PSV-Z-051. The connection with the PSV PC is made using WLAN.
PSV-A-420 Geometry Scan Unit
Laser-based distance sensor for the direct acquisition of 3-D geometry data. The Geometry Scan Unit comprises an optical distance sensor and full software integration with the PSV program (version 8.2 onwards) and it extends the capabilities of the PSV-I-400 scanning head to work as a 3-D geometry acquisition system. Attached to the PSV-I-400 scanning head it measures the x, y and z component of every defined measurement point or reference point. The Geometry Scan Unit includes software modules with the following features:
- User-defined object coordinate system
- Single-shot distance measurement
- Scanning distance measurement
- Visualization of geometry with overlaid vibration data
- Definition of reference points for 3-D alignment (PSV-400-3D)
- Geometry data export to UFF files
On smaller objects a software solution based on image processing is available for PSV-400-3D systems: VideoTriangulation.
Not available for the PSV-400-B Basic Scanning Vibrometer.
PSV-A-430 Acoustic Gate Unit
Designed for applications such as brake squeal measurements. This unit activates the gate input of the PSV-400 if a noise exceeds a certain threshold in a defined frequency band (band pass filter). The scanning measurement starts when the noise is present and pauses when no noise within the band is present. Easy adjustment of the parameters and non-volatile memory for settings.
Parameters: center frequency 500 Hz – 15 kHz; bandwidth 10% - 50% of center frequency ; threshold 2 mV – 20 mV.
