The precision of the PSV-400-3D and PSV-400-3D-M is determined not only by the precision of the sensor, but also by a precise definition of the postion of the three sensor heads in space. The procedure to aquire this specific information, called 3-D alignment is supported for high-precision or high-frequency measurements by this reference object. It features a tripod adapter for VIB-A-T02 tripods for convenient positioning and adjustment in front of the actual measurement object.

Precisely machined and marked reference points with known coordinates and a well-balanced distribution of these marks in space allow a precisely defined basic alignment of the PSV-3D measurement system for perfect results.

External digital camera with macro zoom lens for the PSV-400-3D and PSV-400-3D-M. Allows precise measurement point definition on small samples. Provides higher resolution than the internal camera of the PSV-I-400 for small objects and short working distances.

• Resolution 1034 x 779 pixels
• monochrome
• C-mount
• 1/4" thread adapter for tripod mounting

Includes a 1/3" C-mount macro zoom lens

• Focal length 8.5 mm - 90 mm
• Minimum working distance 178 mm
• Smallest field-of-view 6 x 8 mm

Mounting adapters are provided also for the tripod systems PSV-A-T31 and PSV-A-T34 tripod systems.

Rigid support for three PSV-I-400 scan heads. The angle between the scan heads is optimized and balanced for resolution of all vibrational components (in-plane and out-of-plane). Support for A-CAZ-1000 camera.

The tripod is an essential accessory for the measurment of small parts and very helpful for dynamic strain measurments with the PSV-400-3D.

Software Option for PSV Software (version 8.6 or higher) optimizing the measurement point geometry with the PSV-400-3D and PSV-400-3D-M by image processing. Boosts the accuracy of the geometry measurement of the Geometry Scan Unit PSV-A-420 especially for small objects, for high-frequency measurement and for strain measurement. With small objects and in conjunction with the optional external A-CAZ-1000 high-resolution video camera the performace is high enough to replace the Geometry Scan unit. 

Tripod for the PSV-400-3D system for mounting three sensors heads plus the optional A-CAZ-1000 camera. The tripod system facilitates set-up and shortens the time needed. For one set_up the 3-D alignment (orientation of the sensor heads to each other) can be used for following measurements. Motorized stage for convenient height adjustment up to 2500mm for the top sensor head. Manual tilt of the head assembly with ±45° maximum tilt angle. For bottom-up measurements the head assembly can be mounted without the motorized z-stage.  

• Total weight without sensor heads c. 135 kg
• Space requirement with all 4 feet fully spread about 1625 mm x 1625 mm.
• The tripod system is available for 110 V or 220 V.

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.
