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. more →

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

Custom instrument design and development

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 customized instrumented solution for a particular product, we have expertise to develop a monitoring solution that can potentially demonstrate the effectiveness of that product.

YieldPoint Inc. provides mine operators worldwide with tools, technology and service. YieldPoint's Digital (direct-to-digital) sensors combine accuracy and durability while keeping costs low.
