F4iS Torque Transducer
- Category: Torque torque, SENSORS
The series F4iS Torque Transducer It represents the pinnacle of rotary torque measurement for very high power applications, covering extraordinary ranges from 60 kNm to 120 kNm. This instrumentation behemoth utilizes contactless inductive technology for signal and power transmission, completely eliminating maintenance and ensuring a virtually unlimited service life, even under the most severe vibration and load conditions.
Giant of Inductive Precision
Designed for heavy industry, marine, and wind energy, the F4iS enables testing of wind turbine transmissions, large marine diesel engines, and ship propulsion systems with laboratory-level accuracy (0.1%). Its massive yet optimized mechanical design ensures extreme torsional rigidity, minimizing the sensor's influence on the dynamics of the powertrain under test.
The integrated digital electronics process torque and speed signals (up to 8,000 rpm) with exceptional resolution, offering software-configurable analog and digital (CAN bus) outputs for seamless integration into state-of-the-art test bench automation and control systems.
