Application Note using: FUTEK’s MBA500 Torque and Thrust Biaxial Sensor!
Professional and hobbyist level quadcopters and drones are becoming more popular in the marketplace. Therefore, Drone Propeller Testing has become a necessity for manufacturers. A quadcopter by definition uses its four propellers to generate air lift and change directions.
The propellers work in conjunction with each other to ensure that there are no torque imbalances to send the vehicle spinning out of control.
Firstly, by fixing the MBA500 Torque and Thrust Bi-Axial Load Cell to the motor’s end, we can characterise the thrust and torque generated by each motor and propeller. Secondly, when the motor is powered and rotating, the thrust of the propellers will be measured by the MBA500’s Fz channel. The back-torque of the motor measured by the Mz channel, all while maintaining low crosstalk.
This multi-axial sensor, when used with a USB220, allows for a portable setup where a hobbyist/test engineer can use a laptop to analyse the live test data both in an outdoor setting or in a more controlled, indoor environment.
The MBA500 Torque and Thrust Bi-Axial Load Cell is designed to measure reaction torque moments as well as tension and compression loads, all in one transducer. Temperature compensated and constructed of all aluminium, this torque/thrust sensor is able to achieve an impressive 0.2% nonlinearity and yet provide 150% (22.7 to 68 kg) 125% (90.7 kg) over-capacity. Excellent performance and high precision are achieved through two separate outputs for applied torque and thrust forces.
Therefore, Force/Torque sensors are used for drone propeller testing, product testing, robotic assembly, grinding and polishing. Sensors are used in robotic surgery, haptics, rehabilitation, neurology as well as many other applications.
