Rossi
Measurement Solutions
Rossi's Measurement category brings precision monitoring and intelligent motor control directly to the drivetrain, enabling real‑time torque measurement and decentralized speed regulation for industrial machinery. The product family consists of two complementary solutions: the TorqueMeter (TM Series) — a robust, non‑contact torque measurement system integrated directly onto the gearbox low‑speed shaft — and the dDrive (DDRIVE Series) — a decentralized frequency inverter that mounts directly on Rossi IE2/IE3 electric motors. The TorqueMeter uses strain‑gauge technology and contactless telemetry to provide continuous, real‑time torque data without any modification to the existing gearbox — ideal for condition monitoring, load recording, predictive maintenance, and process optimization in heavy‑duty continuous‑cycle operations. The dDrive decentralized inverter delivers sensorless vector control in an IP65 aluminum housing that eliminates the need for a central control cabinet, reducing footprint, cabling, and cooling requirements.

Why Choose Rossi Measurement Solutions for Smart Drivetrain Integration
The shift toward predictive maintenance and Industry 4.0 connectivity demands real‑time visibility into what the drivetrain is actually experiencing. Rossi's TorqueMeter provides that visibility without the cost and complexity of external torque transducers or load cells. Because it integrates directly with the gearbox, it occupies zero additional space and requires no couplings, alignment, or separate mounting structures. For plants looking to reduce electrical cabinet size and simplify wiring, the dDrive inverter eliminates long motor cables and central VFD panels — each motor has its own intelligent drive, reducing electromagnetic interference, cable costs, and installation labor.
Applications and Industries for Torque Measurement and Decentralized Motor Control
Rossi measurement and control solutions are deployed in operations where reliability, data, and process optimization are paramount. Mining and bulk material handling use TorqueMeter on conveyor drive gearboxes to detect belt overloads and prevent catastrophic failures. Heavy lifting — including port cranes, ship loaders, and offshore winches — relies on real‑time torque monitoring for safe load management. Steel and metal processing lines deploy dDrive inverters on roller‑table motors to achieve precise speed synchronization. Water and wastewater treatment plants use TorqueMeter on clarifier and thickener drives to detect sludge density changes and protect against rake overloads.
