TRANSDUCER DATA & SELECTION
There are several things to consider when deciding which transducer to use:

The crystal diameter should be completely in contact with the bolt end surface.
The outside diameter should be clear of any obstruction.
The frequency should be chosen to suit the bolt length.
The larger the diameter the stronger the signal and therefore better results are obtained by using the largest size transducer that will fit on the bolt.
Boltight recommends the 3/8” diameter, 5MHz transducer as the best general purpose covering 90% or more of typical bolting applications.
