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.
