Magnetostrictive Linear Position Sensor – Profile Style
4
Installation and connection (continued)
4.3
Floating magnets
Note when installing the magnet:
–
To ensure the accuracy of the linear position sensor,
the magnet is attached to the moving member of the
machine using non-magnetizable screws (stainless
steel, brass, aluminum).
–
The moving member must guide the magnet on a
parallel line to the BTL.
–
Distance A between the magnet and parts made of
magnetizable material must be kept to at least 10 mm
(see Fig. 4-4 to Fig. 4-8).
–
For distance B between the magnet and the BTL and
for the center offset C (see Fig. 4-4 to Fig. 4-8) the
following values must be maintained:
Magnet type
BTL5-P-3800-2
BTL5-P-5500-2
BTL5-P-4500-1
BTL6-A-3800-2
BTL6-A-3801-2
The selected distance must remain constant over the entire stroke length.
1)
For optimal measuring results a distance B of 6...8 mm is recommended.
