Pöördenurgaandurid

Pöördenurgaandurid, also known as angle sensors or rotary position sensors, are electronic devices used to measure the angle of rotation of a shaft. They are essential components in various applications where precise control and monitoring of rotational movement are required. These sensors convert the angular position of a rotating component into an electrical signal, which can then be interpreted by a control system.

There are several types of pöördenurgaandurid, each with its own operating principle. Magnetic encoders, for instance, use magnetic fields to determine the angular position. Optical encoders employ a coded disc and a light source to generate signals corresponding to the rotation. Potentiometric sensors, a simpler type, utilize a resistive element and a wiper to produce a voltage output proportional to the angle. More advanced technologies include Hall effect sensors and resolvers, which offer high accuracy and durability.

The output signal from a pöördenurgaandur can be analog or digital. Analog sensors typically provide a voltage or current that varies linearly with the angle, while digital sensors output discrete values representing specific angles or incremental changes. The choice of sensor depends on the required precision, operating environment, and cost considerations.

Pöördenurgaandurid find widespread use in industries such as automotive (e.g., steering angle sensors, throttle position sensors), industrial automation (e.g., robotic arms, conveyor systems), aerospace, and medical devices. Their ability to accurately track rotational movement enables sophisticated control algorithms, enhances safety features, and improves the overall efficiency and performance of complex machinery.
