Wide range of magnetic markers for various applications
The measuring device (waveguide) is made of a special iron-nickel alloy and has an external diameter of 0.7 mm and an internal diameter of 0.5 mm. A copper conductor runs along the entire length of this tube. The measurement process is initiated by a short current pulse. This current generates a magnetic field, which propagates by rotating along the waveguide. At the measured point of the path, a permanent magnet is used as a marking element, the field lines of which are directed at right angles to the electromagnetic field.
In the area of the waveguide where both magnetic intersect, the magnetostrictive effect leads to elastic deformation of the waveguide (deformation at the micro level), which generates a mechanical wave propagating in both directions. The propagation velocity of this wave in the waveguide is 2830 m / s and is practically insensitive to external factors (for example, temperature, shock loads, pollution).
The part of the wave that reaches the far end of the waveguide is suppressed, while the signal entering the signal transducer becomes electric due to the inverse magnetostriction effect. The wave propagation time from the point of origin to the transducer is in direct proportion to the distance between the permanent magnet and the signal transducer. Thus, the measurement of time allows you to determine the distance with exceptional accuracy.
There are 4 magnettrack data processing algorithms :
The track of the magnettrack positioning system consists of a system of markers that are installed along the path of the positioning object so that at least one marker is located at each positioning point in the active zone of the transducer. Markers are globally divided into two types: positional / incremental (PM) and interval (IM).
Below is a table of the main marker parameters for each caliber and type.
Caliber number | Type of amker | D0, мм | Vertical contact area, mm (S) | Lateral Contact Area, mm ( Sw ) |
Caliber 1 | PM | 170 | 15 | 30 (±15) |
Caliber 1 | IM | 170 | 15 | 30 (±15) |
Caliber 2 | PM | 200 | 30 | 60 (±30) |
Caliber 2 | IM | 200 | 30 | 60 (±30) |
Caliber 3 | PM | 260 | 45 | 80 (±40) |
Caliber 3 | IM | 260 | 45 | 80 (±40) |
Caliber 4 | PM | 300 | 60 | 100 (±50) |
Caliber 4 | IM | 300 | 60 | 100 (±50) |
Universal Sensor Holder for Flat Markers
Installation of elements of the magnettrack positioning system is carried out using a universal mounting system consisting of aluminum or steel profiles, corners and guides. Also, in some cases, custom-made fasteners are used to fulfill even the most stringent installation requirements.
Mounting the transducer is carried out using a system of aluminum profiles, allowing you to adjust the position of the transducer in three planes, and also, if necessary, change the angle of the transducer relative to the mounting surface.
The length of the profiles is selected taking into account the installation space at the sensor installation site and allows you to flexibly adjust the position of the transducer relative to the track of magnetic markers for reliable positioning along the entire length of the track.
Markers are fastened mainly using standard clamp holders suitable for installation on various structural elements, such as profile beams, stiffeners, and other protruding structural elements. If it is necessary to place markers on a plane, for example, on the base of the rail, U-shaped fasteners are used, mounted on the surface using bolts, studs or simple welding.
The magnettrack positioning system works reliably where it seems impossible. This video shows only some of the general benefits of magnettrack.
One of the main requirements for reliable systems
Magnetostriction technology allows positioning of objects with micron accuracy
Magnettrack system withstands high shock and vibration loads in accordance with European standards
Magnettrack is based on years- long magnetostriction technology
When creating the Magnettrack system , developers paid great attention to the ease of installation and speed of system startup
It can work in outdoor conditions at low temperatures, as well as in harsh industrial conditions at elevated temperatures
