SIA-7 Product Page
coupled ultrasonics opens up ultrasonic inspection of materials in ways that
contact and immersion ultrasound just can’t do.
Overcoming the mismatch between air and virtually all solids and liquids
required a revolution in how ultrasonics was done. The SIA-7 system was developed to make air coupled
ultrasonics a practical tool for both industry and research.
Of course any system capable of air coupled ultrasonics must make short
work of simple contact and immersion applications.
The SIA-7 is a self-contained ultrasonics analysis system. The units have built-in power amplifiers and digitizers capable of transmitting and receiving ultrasonic signals from a variety of different transducers. Rather than relying on crude pulser receiver technology, the SIA-7 uses high performance Digital to Analog and Analog to Digital converters. This provides maximum flexibility and it also allows the system to get the very most from a set of transducers. For a brief overview of ultrasonics and methods follow this link.
The units can be used as a stand-alone tool or they can be integrated into a larger inspection system. These units are working well in both lab and industrial environments.
SIA-7 units are capable of performing a wide range of measurements with just a few mouse clicks. The measurements include the following:
The SIA-7 unit supports a number of different transducer configurations. With our two channel SIA-7 configuration the same unit can be configured to operate in any of the following modes.
Three In One Signal Processor
The SIA-7 is capable of operating as three different types of ultrasonics systems. In effect, the SIA-7 is three boxes in one. The SIA-7 switches between modes at the click of a mouse. For a more detailed look at the different types of signals, follow this link.
Scanning Frames and C-scans
The SIA-7 can be linked to a scanning frame to produce two-dimensional images. A set of transducers is mechanically scanned back and forth to build up a detailed picture of some part or material. In many instances an ultrasonic image of a part will give a much clearer idea about what’s happening inside the part. Is there a crack or defect? Does the density of the material change throughout the volume?
The SIA-7 can be linked directly to a DaVinci3 scanning frame. The SIA-7 directly controls the frame allowing the user to collect and build images with no external hardware (other than the optional scanning frame).
is an issue there are a wide range of available scanning robotics that can be
substituted to create virtually any size or footprint needed.
addition of an external PC to the SIA-7 and scanning frame, VN Instruments now offers a Tomography option.
Software Development Kit
The SIA-7 can be controlled from a simple text based language. Commands are sent to the SIA-7 through an RS-232 interface. A client wishing to create a specific application can easily integrate the powerful SIA-7 into a larger system. The programming interface operates using simple ‘human readable’ text commands.
SIA-7 units also support several network protocols. Users can easily extract data from the SIA-7 across a network link using either NFS or even FTP. The SIA-7 can be made visible to a Windows™ PC through the network interface.
A wide range of applications have already been built using the SIA-7 as the ultrasonic backbone.
Recommended Peripherals and Configurations
The SIA-7 can be purchased in one of several possible configurations.
