Magnetic Length and Angle Measuring Systems
Magnetic distance and angle measuring systems are a cheap and flexible solution for the implementation of you measurement task.
Operating principle:
The alternating polarization of a coded magnetic scale is scanned by a magnetic sensor without physical contact. One sine/cosine wave is generated per pole. The shape of the sine/cosine wave is electronically interpolated and defines the measurement resolution depending on the interpolation procedure and pole spacing of the magnetic scale.
Special analysis electronics (interpolation) are used to evaluate the sine signal. These generate square-wave output signals from the signal information of the magnetic scale, which are compatible with conventional rotary encoders or optical linear encoders. Magnetic scales for absolute distance measurements are magnetized on 3 tracks: one digital track and two tracks with absolute coding.
Our magnetic distance and angle measurement system consists of a sensor head and a magnetic strip or ring. Magnetic sensors for incremental, absolute or quasi-absolute distance measurements are available in diverse designs. There are different accuracy classes between 5 µm and 1 mm, suitable for any purpose. The magnetic scales can be issued up to a length of 100 m. They are magnetized with pole pitches of 1, 2 or 5 mm. The magnetic scales can be permanently connected to a substrate support tape made of stainless steel.
Magnetic rings, for example in combination with a magnetic sensor, constitute a precise solution with special advantages when it comes to rotatory distance, angle or rotational speed detection. Our magnetic rings stand out through their particularly flat design, resistance against dust, humidity and chips as well as wear-free scanning and high resolution.
