Ultrasonic Transmitting/Receiving Card

Performance Characters:
It operates from a standard PCI bus and can be installed in a desktop or industrial computer slot; can be easily combined with the computer to become a set of four-channel inspection system. It is particularly suitable for automatic flaw detection and ultrasound imaging occasions. The card provides a complete WINDOWS driver, VB, VC, C + + and other programming languages can be used to develop software.
Four-channel ultrasonic transmitter / receiver card is an industrial ultrasonic detection device produced by computer standard PCI bus; can be adapted in commercial desktop computer or portable industrial computer, the board has four completely independent work channels, can also become multi-card cascade according to need and constitute multi-channel ultrasonic detection system. Ultrasonic card and computer combined can be used for industrial non-destructive testing of various fields, and has excellent advantages especially in multi-channel automatic flaw detection and multi-channel ultrasound imaging. In fact, this model represents the latest development trend of ultrasonic testing equipment, it is also the technical object Europe and the United States compete to research and develop, it will be the important equipment base that ultrasonic flaw detection become automatically and visualization.
The ultrasonic transmitter/receiver card our company developed has the features of small board, high integration and flexible channel selection. The card has been equipped with two degrees of freedom displacement control device, and with a complete WINDOWS2000 driver to support software developers to complete a variety of hardware control such as sensitivity adjustment, sampling frequency, sampling depth selection in the form of COM components. Can use such as VB, VC, C + +, CBUILDER and other languages to develop software.
This card can be provided to relevant institutions and scientific research units to build their own detection system or ultrasound imaging system on this basis, and also our company can directly provide a complete detection device to the end user.
