digi-Bolt – Instrumented Rebar

The digi-Bolt allows engineers to monitor the development of strain and load along rigid bolts. As such it is possible to assess the Factor of Safety against steel rupture and the potential to predict the risk of catastrophic structural failure.

The technology can be applied to rebar, threaded bolts, and various other steel elements used in mining and civil construction/engineering.

Utilising inductive strain gauge technology the digi-Bolt provides data that allows engineers to improve designs, installation quality controls, and long-term operational assessment of projects.

Description

Bolt Strain Gauge

Geosystems offer the digi-Bolt strain gauge with 2 to 6 epoxy resin encapsulated strain gauges, in two diametrically opposed slotted channels, which are designed to withstand the traumas of installation.

Each digi-Bolt strain gauge is subjected to a multipoint calibration. The coefficients are written into a microcontroller memory, and a precise linear function is used to enhance linearity, the output signal, and applied strain.

  • Instrumented rebar can be spun in resin
  • Readout head encapsulated in stainless steel tube for
    protection.
  • Microcontroller provides output directly in strain.
  • Each bolt is individually
    calibrated.
  • High survivability to shock and vibration.
  • Easy to install and maintain
  • Low cost peripheral devices for data-logging (digi_LOGGER) and data upload using TCP/IP (GATEWAY)
  • Competitively priced – contact Geosystems for a quotation.
