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.
