Echometer

Boltight has been at the forefront of hydraulic bolt tensioning for over a decade. Our tensioning tools provide fast, accurate and safe solutions to tighten and loosen multiple bolts simultaneously.

ECHOMETER

Echometer is our entry-level ultrasonic bolt measurement product, it is a small battery-powered handheld device that measures bolts up to 2m in length. With a digital screen and simple scroll menus, very little training is required - it is quick and easy to use. It has built-in data recording and reporting through a RS232 interface.

Fully compatible with the Echometer+ including data transfer and ancillary equipment.

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.
