Scope:

 

 

Detection: thickness guage; velocity measurement; spectrum analysis; transducer properties testing; other materials and process monitoring; as EN-standard according probe-calibrating system.

 

Take the UT transducers (probes) for example:

 

To test the pulse width of the echo wave, center frequency, -6dB relative bandwidth, and relative pulse sensitivity of echo wave by the CTS-8077 pulser-receiver and "Goworld-ed" probe-testing software in concert.

 

Tip 1 for the organization:
1.CTS-8077PR linked up with PC via USB cable, and The T/R connector of 8077 with UT transucer by co-axial shielded probe cable, working mode: Mono.
2.The OSC connected with PC through cross network cable, and proof-reading of the data acquired by the PC from OSC.
3.The CH1 (channel 1)-probe connected with the cable.

 

Diagram 4 shows that the OSC probe acquires output signals from the transducer without passing through the PR, which requires no bandwith limit on the receiving circuit of the PR.

 

 

Testing Process
1.In reference to Diagram 4, put all the units in their place and make sure they run well.
2.Make sure there's waveform data to the PC from the OSC.
3.Set up the OSC, turn on "CH1" and "MATH", and set the "MATH" as "FFT algorithm", set the signal source as "CH1".
4.Set the working mode of CTS-8077 as "Mono", and set other paras according to the transducer. As we're now experimenting the 2.5P20 Series, the settings should be followed as:
Working Mode:Mono;Gain:0dB;Pulse Voltage:-200V;Triggering Source:Inner;
PRF:500Hz;LPF:30MHz;Pulse Width:200ns;HPF:1kHz;Damping:50Ω
