Vääntöanturit

Vääntöanturit, commonly known as torque sensors, are devices used to measure rotational force, or torque. They are essential components in various industrial and automotive applications where precise control and monitoring of torque are required. These sensors work by detecting the strain or deformation that occurs in a shaft when torque is applied. This deformation is then converted into an electrical signal, which can be displayed or used by control systems.

There are several types of torque sensors, including strain gauge, optical, and magnetostrictive sensors. Strain gauge sensors are the most common, utilizing thin, resistive wires that change their electrical resistance when stretched or compressed due to torque. Optical torque sensors use light to measure angular displacement, offering high accuracy and non-contact operation. Magnetostrictive sensors employ the magnetostrictive effect, where a material changes its magnetic properties in response to mechanical stress.

The applications of torque sensors are widespread. In automotive testing, they are used to measure engine torque, steering effort, and driveline performance. Industrial applications include monitoring torque in manufacturing processes, calibrating tools, and ensuring the proper functioning of rotating machinery like pumps and motors. They are also found in robotics, fitness equipment, and research and development settings. The data provided by torque sensors enables improved efficiency, enhanced safety, and better product quality.
