T40B Torque Transducer: High‑accuracy Dynamic Torque Measurements for Modern Test Benches

T40B delivers accuracy, stability, and robustness making it the ideal torque transducer for both R&D test benches and end‑of‑line production testing. Its low‑inertia design, advanced digital transmission, and high rotational speed capability support today’s most demanding electric drive and drivetrain applications.

High precision with rock-solid reliability

With its ratiometric measurement, industry‑leading accuracy of 0.05% (linearity incl. hysteresis) and high temperature stability, the T40B ensures long‑term stability and repeatability for consistent results under varying conditions.

Its high vibration resistance safeguards performance in challenging environments and digital, non‑contact signal transmission ensures interference‑immune data transfer.

Key features

HBK accuracy class: 0.05
Low‑inertia torque flange design
Digital, error‑detected data transmission
Ideal for static and dynamic torque measurement
Maintenance‑free operation thanks to non‑contact power supply
Compatible with TIM‑EC (EtherCAT) and TIM‑PN (PROFINET)
Wide accessory selection for seamless integration

Next‑level flexibility

With a nominal torque range from 50 N·m to 10 kN·m, rotational speeds up to 24,000 rpm (depending on the torque range), and optional robust magnetic speed measurement with reference pulse for rotor position detection – the T40B family of torque sensors provides reliability through maximum flexibility for today’s and future measurement tasks.

Typical applications

Designed for electric power testing
Driveline testing in automotive R&D
Paired with HBK power analyzers, which enables instant visualization of torque ripple, it is ideal for modern electric motor development

Easy integration

T40B’s analog and digital interfaces simplify integration into any test bench. Its non-contact power supply and digital signal transmission guarantee fail-safe and maintenance-free operation. The TIM-EC interface module for EtherCAT and TIM-PN for Profinet ensure maximum performance and high flexibility when integrating the torque and rotational speed signals with cutting-edge test bench systems.

Configure the sensor to fit your torque measurement needs

The T40B family consists of a number of variants based on a specific maximum torque range within which specified tolerances and measurement accuracy are guaranteed.
