Ultrasonic box with integrated pulser and receiver rev. 3
OPBOX - USB 2.0 is a complete ultrasonic testing device, suitable for all ultrasonic
measurements, and due to many additional inputs and outputs, it can be used as a controller
for more complicated devices.
The box can work together with following
devices:
2 - 32 channel multiplexer - the
•
OPBOX can control it directly;
Scanner - it has input for incremental
•
encoders;
The box contains one channel pulser &
receiver and can be used with one
transducer or with two (one is sending and
the second receiving) for pulse-echo and
through transmission measurements.
Size: 164mm x 138mm x 34 mm
Power Supply: 9V DC / 2A

- Page 22 Fig. 6 Measurement with delay lines. This is possible with the function “pattern”. It allows to exclude automatically the transmission time through the delay line from the calculations. For this purpose it is first necessary to measure time of flight through the delay line. Than the measured signal should be stored as pattern.
