Rotatsioonisensori

Rotatsioonisensori is a Finnish term that translates to "rotation sensor" in English. It refers to any sensor designed to detect and measure rotational motion or speed. These sensors are crucial components in a wide array of applications, from automotive systems to industrial machinery and consumer electronics.

Common types of rotation sensors include encoders, which are often optical or magnetic. Optical encoders use a coded disc that interrupts a light beam, generating digital pulses proportional to the angle of rotation. Magnetic encoders, on the other hand, utilize magnetic fields and Hall effect sensors or magnetoresistive elements to detect changes in magnetic patterns as the shaft rotates. Another type is the tachometer, which typically generates an analog voltage or frequency that is proportional to the rotational speed. Some rotation sensors also employ gyroscopic principles to measure angular velocity.

The output of a rotation sensor can vary depending on its type and intended use. It might provide discrete pulses, a continuous analog signal, or digital data representing position, speed, or acceleration. These signals are then processed by control systems, microcontrollers, or displays to enable functions such as speed control, precise positioning, or safety monitoring. The selection of a specific rotation sensor depends on factors like required accuracy, operating environment, speed range, and cost.
