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 strip 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 strip.

Special analysis electronics (interpolation) are used to evaluate the sine signal. These generate square-wave output signals from the signal information of the magnetic strip, which are compatible with conventional rotary encoders or optical linear encoders. Magnetic strips 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 strips can be issued up to a length of 100 m. They are magnetized with pole pitches of 1, 2 or 5 mm. The magnetic strips can be permanently connected to a carrier strip 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.

Rotary Encoders
The company Willtec Messtechnik distributes rotary encoders manufactured by the company Scancon from Denmark and the company Fiama from Northern Italy. These rotary encoders are based both on the optical as well as the magnetic measurement principle. Rotary encoders made by Scancon maintain the global top postion of number of pulses at the smallest spatial requirements. Incremental encoders can be issued with an outside diameter between 9 mm and 50 mm with 1000 to 12500 true pulses per revolution and in quill or solid shaft design, combined with various different mechanical or electronic interfaces.
