Torque Transducer with RPM measurement

The TTD Dynamic Torque Transducer is a CE-certified rotary torque sensor designed for precise measurement of torque in rotating shafts and industrial equipment. It is constructed from hardened Stainless Steel 17-4 PH, ensuring high strength, durability, and resistance to shock and overload.

This transducer operates on the strain gauge principle and features full temperature compensation from 10C to 50C, delivering stable and accurate results in industrial environments. Electrical signals are transmitted through a high-quality, low-noise slip ring and brush mechanism, making it suitable for continuous rotary applications.

The torque sensing shaft is mounted on ball journals for smooth rotation and is available in multiple configurations including shaft-to-shaft, flange-to-flange, and shaft-flange combinations. It supports speeds up to 5000 RPM (depending on capacity) and is available in ranges from 50 Nm to 50 kNm.
