rotatsioonisensor

Rotatsioonisensor, also known as a rotary sensor or angular position sensor, is a type of transducer that measures the angle of rotation or the position of a rotating shaft. These sensors convert mechanical rotational movement into an electrical signal that can be processed by other electronic components. They are essential for applications requiring precise control and monitoring of rotational motion.

There are several types of rotatsioonisensor technologies. Absolute rotary encoders, for instance, provide a unique digital code for each angular position, meaning they know their position even after power loss. Incremental rotary encoders, on the other hand, output pulses as the shaft rotates, requiring a reference point for determining absolute position. Other types include potentiometers, which provide an analog voltage output proportional to the angle, and resolvers, which use electromagnetic principles to determine angular position.

The applications of rotatsioonisensor are widespread. They are commonly found in industrial automation, robotics, automotive systems (for steering angle, throttle position), medical equipment, and consumer electronics. Their ability to accurately track and measure rotation makes them critical for controlling motor speed, positioning robotic arms, monitoring vehicle dynamics, and ensuring the proper functioning of various mechanical systems. The choice of rotatsioonisensor depends on factors such as required accuracy, resolution, operating environment, and cost.
