Torque is the rotational force that causes an object to turn. Interface rotary torque transducers are versatile sensors that integrate electronics directly onto the rotating shaft. Engineers measure torque using torque transducers that convert a torsional mechanical input into an electrical output signal, typically a voltage or current. Rotary torque transducers are ideal for dynamic applications where continuous rotation is required, eliminating the need for complex wiring and reducing potential points of failure. They are commonly used in measuring torque for engines, gearboxes, robotics, aircraft, medical devices, tractors, and windmills. If it turns, it needs to be measured.
