Installation
NOTICE
Improper installation
Improper installation can compromise the function of the
BTL and result in damage.
► Ensure that no strong electrical or magnetic fields
are present in the direct vicinity of the BTL.
► Be sure to maintain the specified distances and
separations.

Installation (continued)
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.
– The distanceA between the magnet and parts made of
magnetizable material must be at least 10mm.
A A
– For distance B between the magnet and the BTL and
for the center offset C (see image) 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
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
– When using multiple magnets a minimum separation of
65 mm must be maintained between them.
Any orientation is permitted. Mount the BTL on a level
surface of the machine using the provided mounting
clamps and cylinder-head screws.
In order to avoid resonant frequencies caused by
vibrations, we recommend positioning the
mounting clamps at irregular intervals.
