Edge Solutions
The Edge Node Family — Wireless and Wired
“The endpoints behind every Packaged Solution — wireless and wired.”
Wireless mesh nodes on a secure 2.4 GHz IEEE 802.15.4 network, plus wired devices — cRIO, cDAQ and the Binsfeld TorqueTrak 50 — feeding the same Edge platform. Products are defined by application, not circuitry.

Torque-based Edge Insights: ITM iTestSystem Automated Analytics + Binsfeld TT50
In industrial and marine environments, the drivetrain is often the most critical — and least monitored — part of the system. Rotating shafts transferring torque through gearboxes, couplings, and propellers generate enormous forces that, left unmeasured, become the root cause of unexpected failures, unplanned downtime, and costly maintenance cycles. Traditional torque measurement solutions require shaft…
