OPBOX ver 2.0 - USB 2.0
Mini Ultrasonic Box with Integrated Pulser and Receiver
|
| |
|
|
OPBOX 2.0 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 box can work together with following
devices:
· Multi channel multiplexer
· Phased array systems
· Scanner - it has input for incremental
encoders
The box has an implemented one channel pulser & receiver and can be used with one transducer or with two (one is
sending, and the second one receiving).
