Get A Good SignalNow all you need is a good
echo, then |
| Next step, you need to get a good
signal. Put
some "goop" on the head of the bolt.
You can use any fluid that acts as a couplant between the bolt's head and the transducer. Ultrasonic pulses will not transmit through the air gap, so displace the air with a coupling fluid that will transmit pulses. Place your ultrasonic transducer onto your bolt's head (or threaded end). Move the transducer until you get a good signal. Manufacturer #1 is using a magnetic transducer so there will not be any movement of the transducer during bolt tensioning. Manufacturer #1 will tighten the bolt from the nut end. Therefore the transducer can be left undisturbed during bolt tensioning. This transducer is the dark blue rectangle with the black electrical cable. The other end of this cable is plugged into the SureBolt BNC connector. We recommend using a magnetic transducer for consistent results. |
 Echo Time. See animation page. |
Move this pointer to
select the echo you
want. Then press
this large yellow button. The top graph is just a zoomed in look at where the green/red pointer is looking. This pointer changes its color from green to red as a reminder of the next step.
See below for each of the screens in this example. You can jump to any screen you want, but we recommend using the Previous Step or Next Step links above.
