OPCARD 2.0
PCI-bus Ultrasonic Card
with Integrated Pulser and Receiver
The card has an implemented one channel
OPCARD 2.0 is a complete ultrasonic testing pulser & receiver and can be used with
one transducer or with two (one is
device, suitable for all ultrasonic
sending, and the second one receiving).
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;
