Ultrasonic flaw detector OPCARD - 01/100

OPCARD -01/100 is a complete ultrasonic testing device, suitable for all ultrasonic measurements, and due to many additional digital inputs/outputs and internal processor it can be used as a controller for more complicated devices. The card can work together with following devices: · 32 channel multiplexer - the card can control it directly; · Scanner - it has input for incremental encoders; The card has an implemented one channel pulser & receiver and can be used with one transducer or with two (one is sending and the second receiving). OPCARD -01/100 is a short PCI card and can be installed in a standard PC.
