Rotary encoder provides an inexpensive way to measure axis rotation or for example the rotation of the motor in conveyor lines. In an electric motor, the frequency converter can adjust the engine speed using the measurement provided by the rotary encoder. Rotary encoders are available with different pulse volumes, which makes it very easy to combine it with controls.
There are both contact and contactless sensors with several different measuring techniques, such as potentiometer, inductive and magnetic contactless. Output signal is analog potentiometer / 0,5-4,5 / 0-10 VDC or 4 – 20 mA, or digital.
Angle sensors measure the angle between two objects. The angle measurement can be either absolute or incremental: absolute sensors provide the angle reading straight away after switching the sensor on whereas incremental sensors require for you to visit the home station first and start the measuring again from there.
