AEROSPACE LINEAR FORCE AND ROTARY TORQUE SENSORS:


    Linear Force and Rotary Torque Sensors:


    Honeywell’s force and torque sensors are often ideal for a number of measurement and feedback applications on aircraft. These sensors measure the forces applied by the pilot or co-pilot to the elevator, aileron, and rudder flight control systems. Sensor output is used both by auto-pilot and flight data recorder. Force is measured using integral load cells, and conditioned using internal electronics prior to transmission to the flight data recorder. A mechanism in each sensor allows the device to continue to function as a control linkage in the unlikely event of sensor failure.
