Flange-to-flange rotary torque meter with speed measurement

The RTSB Rotary Torque Meter is a cutting-edge, high-precision torque measurement solution engineered for demanding industrial and automotive applications. Combining advanced strain gauge technology with a contactless signal transmission system, this sensor delivers unparalleled accuracy in real-time torque monitoring, making it indispensable for optimizing performance, safety, and efficiency in rotating machinery.

The RTSB comprises two core components: a rotor and a stator. The rotor, equipped with precision strain gauges, detects torsional deformation between its front and rear flanges, converting mechanical torque into a millivolt-level analog signal. This signal is wirelessly transmitted to the stator via a non-contact inductive coupling system, eliminating the need for slip rings or physical connectors. The stator processes the raw data into standardized outputs—0-5V, 0-10V, or 4-20mA—proportional to the applied torque. This seamless integration ensures noise-free signal acquisition, even in high-vibration or high-RPM environments.

Key advantages of rotating torque transducer RTSB:

• Bearing-Free Design: By removing traditional bearings, the RTSB eliminates mechanical wear, achieving a maintenance-free lifecycle ideal for continuous operation in industries like automotive manufacturing or energy production.

• High-Speed Performance: Capable of operating at speeds up to 15,000 RPM, the sensor excels in applications such as turbocharger testing, electric motor validation, or aerospace propulsion systems.

• Bidirectional Measurement: Accurately captures torque in both clockwise and counterclockwise directions, critical for reversible systems like wind turbine pitch controls or hybrid vehicle drivetrains.

• Wide Capacity Range: Available in 10 capacities from 50Nm to 10,000Nm, the RTSB adapts to tasks ranging from micro-motor calibration to heavy industrial gearbox testing.

The RTSB's space-saving, flange-to-flange design minimizes axial footprint, enabling installation in tight spaces without costly system redesigns. Its hollow shaft configuration allows seamless integration into existing drivelines, whether in automotive powertrains, conveyor systems, or robotic joints. This compactness is particularly valuable in electric vehicle (EV) testing, where space constraints around motors and inverters are common.

• Automotive: Validates clutch engagement torque, measures transmission efficiency, and monitors EV regenerative braking systems.

• Industrial Automation: Ensures precise torque control in CNC spindle motors, packaging machinery, and robotic assembly arms.

• Aerospace: Tests helicopter rotor shafts and jet engine components under extreme rotational stresses.

• Energy: Monitors torque in wind turbine gearboxes and hydroelectric generators to prevent overload failures.

• R&D Labs: Facilitates material fatigue studies and prototype validation for next-gen machinery.

The RTSB Rotary Torque Meter redefines reliability in torque measurement, merging laboratory-grade precision with industrial ruggedness. Its ability to deliver real-time data at unprecedented speeds empowers engineers to enhance operational efficiency, reduce downtime, and meet stringent quality standards. Whether deployed in high-stakes automotive testing, smart manufacturing, or renewable energy systems, the RTSB stands as a testament to innovation, proving that precision and durability can coexist in even the most challenging environments.
