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

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.

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.

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.

Fiber optic ringlight for illumination of  the test object and contrast enhancement.

For housing and transporting the Data Management System, Vibrometer Controller and Junction Box. Wooden worktop for the TFT monitor, mouse and keyboard. Front and rear covers with storage space for the keyboard and the main connection cable. Removable bottom plate with wheels.

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.

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 availble for PSV-400-3D systems: VideoTriangulation.

Not available for the PSV-400-B Basic Scanning Vibrometer.

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.
