T12HP

T12HP: High‑precision Torque Sensor for Test Benches

The T12HP torque sensor combines class 0.02 accuracy with HBK’s FlexRange™ technology, eliminating the need to manually switch the measuring range as seen with typical dual‑range sensors. Engineers can trust the results across low‑amplitude oscillations and high‑load events – making it ideal for transient analyses, NVH studies, and efficiency mapping on e-mobility test benches.

Key features

• Nominal (rated) torque 100 N·m, 200 N·m, 500 N·m, 1 kN·m, 2  kN·m, 3 kN·m, 5 kN·m and 10 kN·m
• Nominal (rated) rotational speeds of 10,000 to 22,000 rpm
• Large measurement frequency range up to 6 kHz (-3 dB)
• Fast digital measurement signal transmission of 4800 measured values/s
• High resolution of 19 bits (integrative method)
• Monitoring functions
• Excellent temperature behavior with TC₀ of 0.005%/10K
• Minimal linearity deviation, including hysteresis of 0.007%
• Extensive options

Maximum precision in highly dynamic torque measurements

The T12HP torque transducer sets the benchmark for high‑precision dynamic torque measurements, combining exceptional accuracy, unmatched flexibility, high dynamics and carrier‑frequency (CF) accuracy with digital signal conditioning without data loss – in a single sensor.

FlexRange – continuous accuracy across your entire measurement range

Traditional dual‑range transducers can introduce a step at the range boundary. All FlexRange™ enabled sensors keep accuracy continuous, maintaining precision and performance without discontinuity – ensuring small signals remain credible even as tests sweep into higher loads.

This continuity is crucial for diagnosing torque ripple, transient behaviors, and load‑dependent phenomena that influence real‑world efficiency and drivability.

Typical applications

• E‑mobility and powertrain test benches (fueled/unfueled): analyze transient torque, inverter/motor behavior, and efficiency maps with confidence across ranges
• Brake test benches (passenger car and truck): capture full‑brake vs. residual‑brake torque, thermal fade and control response - even at low‑level signals
• Clutch, damper and driveline component testing: investigate stick‑slip and damper‑curve effects with high repeatability at small torques
• Tire and wheel NVH: measure high‑speed uniformity torque ~10 kN·m while resolving low‑level friction torque (~50 N·m) for adhesion, shear and noise studies

Robust design for maximum ROI

The T12HP torque sensor is designed for clean signals with excellent vibration resistance to protect data integrity on demanding test benches. With user‑friendly configuration tools such as T12HP Assistant and CAN parameterization, and a wide measuring range from 100 N·m to 10 kN·m, T12HP maximizes both measurement quality and long‑term investment value.

Easy system integration for uninterrupted digital signal transmission

System integration is straightforward thanks to EtherCAT and PROFINET interfaces when combined with the TIM-EC and TIM-PN modules, respectively. When testing in automotive powertrain labs, you can seamlessly integrate your torque measurements via CAN bus.
