These torque sensors determine torque up to 30,000 rpm, measure with an accuracy of up to 0.01% and have less than 1 microvolt of noise even in the low torque range. They can function under extreme conditions and is not impaired by dirt or dust. A contactless measurement principle means the sensors are insensitive to vibration and resistant to wear and changes in temperature or humidity. The sensors’ smart self-calibration allows them to adapt to changing conditions in real time and during a machine’s full operation. They are optimized for use in smart networked systems and automatic M2M communication.
