Next step, you need to get a good
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
