Why use the Inductive (iS) model versus Optical variants for 20,000 Nm torque banks rotating at 12,500 RPM?

Optical torque transducers, while excellently immune to EMI noise (high-voltage traction inverters), can fail due to lens fouling if industrial grease or oil is released under centrifugal force at high speeds (up to 12,500 RPM) on the test bench. The F23iS (Inductive) version extracts data using magnetic proximity technology on toothed tracks. This technology does not depend on a clean laser emitter, allowing it to operate under constant stress on lubricated 20,000 Nm test trains with complete stability and unwavering inertia (0.1485 kgm²).

When rotating at such a high speed, is the PCD anchor that forms the transverse coupling of the F23iS flange safe?

Absolutely. A spurious lateral oscillation at 12,500 RPM would be fatal for the adjacent instrumentation. That's why Atesteo has eliminated smooth friction couplings, designing a massive physical core in the F23iS supported by a meticulously stabilized 218.0 mm Pitch Circle Diameter (PCD) base. This anchor homogeneously distributes any tensile disturbance or rotational deformation, guaranteeing perfect transfers of its metrological class (0.05%).

The F23iS series redefines industrial dynamic testing capabilities, offering astonishing torque control for test benches where cross-inertia and high speed are the norm. Calibrated to monitor a bandwidth of 20,000 Nm (20 kNm) on purely rotational axes, this transducer stands out for its thermal and mechanical capacity to sustain up to 12,500 continuous RPM. To channel such inertial stress without compromising stator deformation, the central rotor transfers its load point to a 218.0 mm PCD flange mounting grid (249 mm outer circumference), shielding mechanical oscillations with a stabilizing rotor inertia of 0.1485 kg·m².

Featuring inductive telemetry and magnetic pickup tracks with an optimized cutoff pulse, the F23iS is ideal for environments contaminated by grease, heavy vapors, or splashes that would disable optically based sensors. This passive hardware foundation ensures clean data transfer with a strict Accuracy Class of ≤±0.05%, remaining stable even during extreme acceleration.
