Module multiplexer OPPA 32

phased arrayfor ultrasonic inspection systems

OPPA32 is particularly well suited for ultrasonic measurements as well as other kinds of measurements which need many channels. Together with the card OPCARD 2.0 or OPBOX 2.0 and ultrasonic probes it could be used as complete ultrasonic testing device. Each channel has separate pulser & receiver. Specific equipment predisposes it to work in phased array mode. The multiplexer together with OPCARD 2.0 - PCI-bus Ultrasonic Card or OPBOX 2.0 - Ultrasonic testing box, becomes complete ultrasonic testing device. Multiplexer operates with 32 ultrasonic transducers, and thus has 32 independent transmitting and receiving channels. Each channel is equipped with individual delay lines, which can be programmed so that the pulse transmitter on the channel is being shifted in time relative to other channels. Features: - 32 independent transmitting - receivingchannels; All channels may be used at once for beam forming; - USB or RS232 control interface - BNC Trigger Input - BNC Signal output - 12V/2A power supply Together with OPCARD 2.0 or OPBOX 2.0 and delivered Software Package: - many phased array ways of measurement - various image processing: - conventional phased array processing, - SAFT, - CUDA.
