AUTOMOTIVE POSITION SENSOR Electric Power Steering Compliant Torque and Position Sensor BI Technologies steering sensors provide high accuracy in challenging environments. BI sensors are designed for today’s high performance Electronic Steering Systems to provide critical position and torque loading information. Dual redundant outputs provide added reliability and system diagnostic options. The patent pending BI design allows for independent concentric rotors in the same package. This allows position and torque drive shafts to be non-concentric without overstressing the sensor or affecting accuracy. BI’s expertise in innovative sensor packaging is a key element in the development of solutions for custom applications.
