Why does the HSTT2eS omit the Dual Flange (44.0 mm) option of the Type 1 version if both reach 40,000 RPM?

That's correct, both sensors share the brutal 40,000 RPM ceiling (strict High Speed) under the same phantom inertia of 0.0003 kg·m². However, the HSTT2eS deliberately increases its torsional range to 200 Nm compared to the fragile 100 Nm of its smaller sibling. Operating 200 Nm of torsional tension on a tiny 44.0 mm flange would cause shearing of the mount. Therefore, Atesteo eliminates the lower compatibility and unifies the mechanical grip, guaranteeing a pure 66.0 mm PCD mount, safely dissipating the concentric load to protect the astonishing class of the 0.05%.

Can the optical reader (High Speed) survive the transverse heating of testbeds rotating at more than 30k RPM?

To prevent parasitic overheating, Atesteo eliminates mechanical inductive components. The 'eS' system implements transmission rings using only light beams in flight. Light is frictionless, preventing surface heating and the intrinsic thermal expansion or drift that would corrupt the measurement at a base 30,000 RPM (capable of reaching a peak of 40,000 RPM without burning out the rotor). A direct byproduct of being metal-blind and aseptic is that it becomes completely immune to the EMI noise emitted by aerospace e-axle inverters.

The HSTT2eS (High Speed Torque Transducer – Range 2) represents the pinnacle of torque within the Atesteo ballistic family, capable of delivering cross-vectors of 200 Nm on ultra-high-speed test benches. Its micro-structured design is exclusively for severe e-axle turbines, aerospace robotics, and very high-speed electric motors. Despite doubling the torque capacity of its smaller counterparts, the HSTT2eS maintains an astonishing rotational ceiling of 30,000 RPM sustained and 40,000 RPM peak (under optional test configuration). All of this is integrated into a concentric central coupling via a flush-mounted 66.0 mm PCD flange, resulting in an inertial mass of just 0.0003 kg·m², which prevents fracture due to parasitic centrifugal force.

Like all "eS" generation technology, the Wheatstone bridge capture and transfer relies not on conventional electromagnetic rotors, but on a purely optical telemetry gun. The elimination of magnetic components provides the HSTT2eS with complete EMI shielding against radiated voltage spikes (dV/dt) from adjacent high-voltage electric motors. The result is a completely pure and friction-free measurement profile of class ≤±0.05%, unaffected by frictional heating. Ideal for testbeds exploring the dynamic limits of tomorrow's motors.
