dRebar
|
YieldPoint’s d-Rebar measures how the strain or load develops along rigid bolts, such as resin rebar, and hence to assess the Factor of Safety against steel rupture. The technology is applicable to rebar elements, threaded bolts, and a variety of other steel elements used in mining, civil and construction projects. It has the potential to predict the risk of catastrophic structural failure: in fact the d-Rebar data can enhance many aspects of engineering design.

The physical instrumentation of the d-Rebar is recessed into a 3.2mm wide groove which is milled into the steel bolt. Typically the instrumentation consists of up to six (6) axially configured long base-length strain gauges (300-600mm baselength). The strain gauges are encapsulated within an epoxy resin and are designed to withstand the rigors of bolt installation using standard procedure.
Installation Precautions:
Installing instrumentation with a rock drill can be challenging even for the toughest product. Care must be taken to ensure that the drill is well aligned with the borehole.
Features:
Instrumented rebar that can be spun in resin
Available with 2 to 6 strain gauges in two diametrically opposed slotted channels.
Readout head encapsulated in stainless steel tube for protection.
Microcontroller provides output directly in m
Each bolt is individually calibrated.
Immunity to hostile environment
High survivability to shock and vibration
Easy to install and maintain
Low cost peripheral devices for data-logging (d-Logger,BluLink or BluLogger) and data upload using LTE-M. Wifi, or Ethernet (BluGateway)
Wireless mesh using 900MHz 1for1 radio.
