Rotary torque sensor and its applications
2024-12-24
Rotary torque transducer is an advanced device engineered to measure torque, or rotational force, applied to a rotating system such as a shaft, motor, or gearbox. It works by detecting torsional forces transmitted through a rotating element using strain gauges. These gauges measure deformation caused by torque and convert it into an electrical signal. This signal can be transmitted, monitored, recorded, or analyzed, making the sensor essential for real-time performance evaluation and process optimization. Rotary torque sensors are classified into two primary types based on their data transmission method. Slip-ring sensors use slip rings or brushes to transmit electrical signals from the rotating shaft to stationary electronics. These are widely used for high-speed and continuous rotation systems. On the other hand, non-contact sensors utilize wireless or telemetry systems to transfer data without physical connections, offering advantages like reduced wear, enhanced durability, and higher reliability in demanding applications. Structurally, rotary torque sensors vary, with popular types including flange type, shaft type, square drive type, and hollow type designs, catering to diverse application needs. Some advanced models integrate additional functionalities such as speed or angle measurement.

A rotary torque sensor measures the torque applied to a screw or bolt during tightening, converting the rotational force into an electrical signal. This data is invaluable for ensuring that the applied torque aligns with predefined specifications, preventing under-tightening or over-tightening, both of which can compromise the integrity of the assembly. The sensor is versatile and integrates seamlessly with a variety of tools, including electric and pneumatic screwdrivers, torque wrenches, and even automated tightening systems. Its ability to record and analyze data further supports quality control, enabling manufacturers to achieve consistency and reliability in their fastening operations.
Dynamic torque transducers are vital tools for accurately measuring the torque produced by a motor. This information helps evaluate motor performance, optimize efficiency, and ensure reliability in applications ranging from automotive and industrial machinery to robotics and aerospace systems. Selecting the right rotary torque sensor is critical for accurate motor torque measurement. Begin by choosing a sensor that matches the motor’s torque and speed specifications to ensure reliable performance. Once selected, install the torque sensor between the motor and the load or driven component, typically using couplings to ensure secure and precise connections. During operation, the torque sensor captures the rotational force generated by the motor shaft and converts it into an electrical signal. This signal is transmitted to a monitoring system or data logger, often alongside other parameters such as rotational speed (RPM).
