Product Description

Kunwei Technology's high-precision joint torque sensor is a core sensing product developed by the company based on aerospace-grade precision measurement technology specifically designed for accurate measurement of rotational shaft torque. Utilizing advanced strain measurement principles and an integrated structural design this product enables real-time precise detection of static and dynamic torque values providing critical data for performance evaluation safety control and condition monitoring of rotating machinery. Key product highlights include: First it delivers exceptional measurement accuracy and stability with overall precision exceeding ±0.1% FS ensuring reliable data under prolonged operation and complex conditions. Second it offers outstanding dynamic response accurately capturing rapidly changing torque signals. Finally its compact rugged mechanical structure and flexible mounting design enable seamless integration into various transmission systems with minimal impact on existing system inertia and stiffness. Key application industries span multiple sectors including: - Integration into humanoid robot joint modules providing force feedback for each joint to enhance sensitivity testing; Industrial automation and robotics (e.g. joint module torque feedback servo motor performance testing) new energy vehicles (e.g. electric drive system efficiency testing drive shaft torque monitoring) and high-end scientific research and precision manufacturing (e.g. micro-torque precision measurement material performance testing). It serves as a critical component for enhancing equipment intelligence and achieving precise control.

Product Specifications

Kunwei Technology's torque sensors have set an industry benchmark in terms of core performance indicators. Their typical value of static comprehensive accuracy (including nonlinearity hysteresis and repeatability) is better than ±0.1% of full scale (FS). They feature high dynamic accuracy and response frequency which can meet most high-speed dynamic measurement requirements. The product range is comprehensive covering from millinewton-meter level micro-torque to tens of thousands of newton-meter level large torque and can meet different applications from precision instruments to heavy machinery. The sensors are made of high-strength alloy materials and precision machining processes with extremely high overload capacity (usually ≥150% FS) and anti-fatigue performance ensuring safety and long service life under impact loads. The products come standard with excellent environmental adaptability with a protection level of up to IP65 and above. They have undergone precise full-temperature range compensation effectively suppressing the drift of zero point and sensitivity caused by temperature changes. The signal output methods are flexible providing various options such as analog voltage/current and digital interfaces which is convenient for system integration.
