What is the purpose of optical shielding (eS) in benchtop transducers with an inertia of 0.1485 kgm2 such as the F23eS?

Heavy-duty 20,000 Nm mechanical test benches often incorporate e-axle platforms or mega inverters that generate significant electrical noise (severe EMI - Electromagnetic interference dV/dt). A generic transducer would fail at the first point of tension. The F23eS family replaces traditional magnetic measurement with parallel conversion using light (optical). This light ring eliminates any electrical vulnerability by shielding the transducer, while the generous inertia, anchored to its 218.0 mm (0.1485 kgm²) PCD, prevents flexural vibrations of the frame.

Does measuring using aversa light technology mean that it reduces its mechanical rotation limit to a base 13,000 RPM?

Correct, but positive. The core of a serial F23 caliber can oscillate up to a true 13,000 RPM without inductive mounting. While the optics are more sensitive to spilled thick oils than an inductive mount, this structural 13,000 RPM ceiling ensures it can withstand severe naval and industrial testing without tearing the 218.0 mm PCD flange that connects the system to the load bench. It's the perfect symbiosis of clean digital V26 immunity without sacrificing raw rigidity.

The F23eS series addresses massive rotational measurement from a purely electromagnetic perspective, focusing on test benches dominated by large traction inverters. Scaled on a robust torsional foundation of 20,000 Nm (20 kNm) nominal force, the equipment integrates a central 218.0 mm PCD flange coupling that stabilizes a passive inertia of 0.1485 kg·m². This aseptic physical matrix is capable of withstanding unleashed dynamic cycles on test beds of up to 13,000 RPM at continuous structural ceiling, ensuring that the metric core does not collapse under the destructive frequency derivatives generated by heavy electric motors.

The key differentiator of the F23eS (eS variant) is the incorporation of Optical Telemetry (Light Transmission) shielding. By replacing traditional galvanic rings and magnetic pulses with a purely light signal conversion to the free-flowing parallel conductive metals, it completely immunizes the extensiometric transfer against dV/dt magnetic noise from the high-voltage drivers. This allows for the export of pristine data and certification of an unalterable Accuracy Class of ≤±0.05%, unaffected by any electromagnetic interference (EMI) spikes from the adjacent propulsion stage. Ensure your tests by injecting full shielding; consult the Torque Sensor category isolated, or modernize your engineering benches directly from the Guemisa Homepage.
