Non-contact shaft-to-shaft rotary torque sensor with encoder

The RTSA Non-Contact Rotary Torque Sensor represents a leap forward in torque measurement technology, combining wireless innovation with precision engineering to deliver real-time, dual-parameter monitoring in rotating systems. Designed for applications demanding both accuracy and durability, this sensor simultaneously measures rotational torque and angular position, transmitting data via 0-5V, 0-10V, or 4-20mA analog outputs for torque and pulse signals for angle measurement. Its dual-channel capability eliminates the need for multiple sensors, streamlining data acquisition in complex mechanical systems.

The RTSA rotating torque meter employs a shaft-to-shaft configuration, enabling direct integration between drive and load shafts through standard couplings. Unlike traditional slip-ring sensors, it utilizes a contactless inductive coupling system—relying on coils to transmit signals without physical contact. This design eradicates wear, reduces maintenance costs, and ensures longevity, even in high-speed or high-cycle environments. The absence of mechanical brushes or slip rings allows seamless operation at rotational speeds up to 6000 RPM, making it ideal for dynamic applications like turbine testing, electric motor validation, or high-performance automotive powertrains.

With torque capacities spanning 5Nm to 500Nm and bidirectional measurement (clockwise/counterclockwise), the RTSA adapts to diverse industrial needs. Its ability to capture real-time torque and angle data is critical for applications such as:

• Nut runner calibration: Ensuring precise fastener torque in assembly lines to prevent under/over-tightening.

• Hand tool testing: Validating screwdriver or drill torque consistency for quality assurance.

• Powertrain analysis: Monitoring clutch engagement or transmission efficiency under load.

• R&D prototyping: Enabling iterative testing of rotating machinery, from drones to industrial pumps.

Beyond standard configurations, the RTSA can be tailored to niche requirements. Custom torque ranges, specialized output protocols (RS485), or unique mechanical interfaces (flanges, keyways) are available for OEMs and research teams. For IoT-enabled systems, wireless telemetry options facilitate remote monitoring, while temperature-compensated models maintain accuracy in thermal extremes.

The RTSA redefines rotary torque sensing by merging non-contact efficiency with laboratory-grade precision. Its ability to deliver synchronized torque and angle data in real time empowers industries to optimize performance, reduce downtime, and enhance product reliability. Whether deployed in aerospace propulsion testing, smart manufacturing, or renewable energy systems, the RTSA stands as a cornerstone of innovation, proving that advanced measurement can coexist with rugged practicality.
