Global joint integrity specialist and engineering services company Hydratight has introduced a new ultrasonic instrument designed to measure and record bolt strain or load for safety and precision in fastening applications.

BOLTSCOPE II is an easy-to-operate, but very accurate instrument that measures bolt strain using the well proven principle of measuring the time of flight of an ultrasonic signal. The signal is generated by a transducer and an advanced electronic clock measures the time taken to return to the transducer after reflection from the far end of the bolt or stud.

The BOLTSCOPE II is particularly useful for verifying fabrication and manufacturing processes or confirmation on construction sites that local bolt tightening processes are in control. The technology is also particularly applicable to bolts securing machinery such as crushers in mines and quarries or turbines in energy and resources.

Commercial Leader of Hydratight in Australia, Mr Neil Ferguson explains that ultrasonics are also highly useful in confined spaces where the use of a torque wrench is not possible without significant removal of components around the bolt in question.

BOLTSCOPE II ultrasonic instrument works with all bolt tightening systems, monitoring the fastener during the tightening process to ensure accurate initial loading. The retained load in the fastener can be monitored at any time.

Key features of BOLTSCOPE II ultrasonic instruments:

  • Capacity to store up to 10,000 fastener measurements in up to 512 application groups
  • Minimal application data required
  • Easy-to-use interface with direct access keys
  • Measures reference length of fastener to better than four decimal places resolution
  • Lightweight and compact
  • Rugged design for production and site environments
  • Measures fastener lengths up to 6.4 metres
  • Simultaneous display of fastener stress, elongation, load and time of flight
  • Multilingual capabilities (English, French, German, Spanish, Italian and Russian)
  • BOLTSCOPE Firmware displays the load, stress or elongation of fasteners through operator setting and pre-loaded compensation data
  • Built-in A-Scan waveform displays help the user to place transducers correctly by verifying signal reception
  • Material and joint data can be uploaded and downloaded to a PC directly using the Stressware provided
