Digital Instruments

Our highly innovative digital product line as designated by the suffix ‘d-‘ includes an embedded microcontroller that provides highly accurate measurements reported in real-world units. This technology provides many key advantages to our users.

Our digital instrument product line can be divided into three categories: Ground movement monitoring, Reinforcement monitoring, and Geoenvironmental monitoring.

Ground Movement Monitoring

PullTest

A turnkey system with both electronics and hydraulics to collect load0displacement response during QA underground pull tests on support elements…

YieldPoint has worked closely with bolt manufacturers around the world such as International Rollforms (d-Split), Normet (d-Bolt), Jennmar (d-YieldLok), DSI (d-Threadbar) to develop custom solutions for rock reinforcement products. Currently, we are in the early stages of developing an instrumented Swellex bolt. If you require a customized instrumented solution for a particular product, we have the expertise to develop a monitoring solution that can potentially demonstrate the effectiveness of that product.
