Vääntömomenttianturi

Vääntömomenttianturi is a Finnish term that translates to torque sensor. It is a device used to measure the torque applied to a rotating shaft or a stationary object. Torque, a rotational force, is a crucial parameter in many mechanical systems.

Torque sensors work on various principles, including strain gauges, magnetostrictive effects, and optical methods. Strain gauge-based sensors are common, where changes in electrical resistance due to material deformation under torque are measured. Magnetostrictive sensors utilize the property of certain materials to change their magnetic properties when subjected to mechanical stress. Optical sensors can measure torque by detecting changes in light polarization or diffraction patterns caused by applied forces.

The applications of torque sensors are widespread. They are used in automotive testing to measure engine torque, transmission performance, and braking forces. In industrial settings, they monitor motor performance, control robotic arms, and ensure the proper tightening of fasteners. In research and development, torque sensors are essential for understanding material behavior and validating mechanical designs.

Measurements from torque sensors can be used for monitoring, control, or calibration purposes. They provide valuable data for optimizing efficiency, ensuring safety, and maintaining the integrity of mechanical systems. The accuracy and range of a torque sensor depend on its design and intended application.
