PCI bus ultrasonic transmitter/receiver card

adopt standardsPCIBus operation, can be installed in desktop computers or industrial computer slots for use. Can be easily combined with a computer to form a four channel flaw detection system. Especially suitable for automatic flaw detection and ultrasonic imaging scenarios. This card provides completeWINDOWSDriver program, software development can be usedVBTheVCTheC++Waiting for programming languages.

Four channel ultrasonic emission/The receiving card adopts computer standardsPCIA bus based industrial ultrasonic testing device that can be adapted to commercial desktop computers or portable industrial control computer environments. The board is equipped with four completely independent working channels and can also be cascaded with multiple cards as needed to form more channel ultrasonic detection systems. The combination of ultrasonic cards and modern computers can be used in various fields of industrial non-destructive testing, especially in multi-channel automatic flaw detection and multi-channel ultrasonic imaging, which have excellent advantages. In fact, this mode represents the latest development trend of ultrasonic testing equipment and is also a technology object that European and American countries are competing to develop. It will be an important equipment foundation for the development of ultrasonic testing automation and imaging.

Our company's developed ultrasonic transmitter/The receiving card has the characteristics of small board size, high integration, and flexible channel selection. The card is equipped with a two degree of freedom displacement infection control device and is also equipped withWINDOWS2000Complete driver program toCOMThe form of components supports software developers to complete various controls on hardware devices, such as sensitivity adjustment, sampling frequency, sampling depth selection, etc. Developing software can be done using methods such asVBTheVCTheC++TheCBUILDERWaiting for language.

We can provide relevant universities and research institutions with their own detection systems or ultrasound imaging systems based on this, or our company can directly provide complete detection devices to end users.
