Installation and connection (continued)
5.3 Floating magnets
Observe the following when installing the magnet:
– To ensure the accuracy of the magnetostrictive linear
position sensor, fasten the magnet to the moving
member of the machine only 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. 5-4 to Fig. 5-8).
– For distance B between the magnet and the BTL and
for the center offset C (see Fig. 5-4 to Fig. 5-8) the
following values must be maintained:
Magnet type Distance B
1)
Offset C
BTL5-P-3800-2 0.1…4 mm ±2 mm
BTL5-P-5500-2 5…15 mm ±15 mm
BTL5-P-4500-1 0.1…2 mm ±2 mm
BTL6-A-3800-2 4…8 mm
2)
±5 mm
BTL6-A-3801-2 4…8 mm
2)
±5 mm
1)
The selected distance must remain constant over the entire measuring
length.
2)
For optimal measurement results: 6…8 mm
