Dual DF Torque Sensor 2 – 1,000 Nm and 20,000 RPM
- Manufacturer: ATESTEO
- Category: Half torque (100-1,000 Nm), Rotary, Torque sensor
The DF Dual 2 from the Atesteo DF family measures torsional variations in test benches and industrial applications. Rated torque: 1,000 Nm. Maximum speed: 20,000 rpm. Mounting: PCD 101.5 mm.
The stator is a split ring stator and is mounted around shafts already integrated into the system.
Measurement principle: Strain gauge modules (DMS) coupled to the rotor and inductive digital transmission. Data and energy transfer between rotor and stator is contactless, requiring no maintenance or wear.
Accuracy class: 0.05%. Rotor inertia: 0.0033 kgm². Outputs via TCU5: frequency, analog (±10V), and CAN 2B protocol. Power supply: 24 V DC. Operating temperature: 0 °C to +80 °C. Protection: NEMA IP54. Rotor: Ø128 mm and 48 mm in length. Rotor/stator weight: 1.6 kg / 0.96 kg.

Technical queries (FAQ)
How do I mount the DF Dual 2 torque sensor?
Around axes already integrated into the system, by its split ring stator.
How are data and power transferred in the DF Dual 2?
Inductively between the rotor and the stator, without physical contact.
