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.
For dimensions, see Fig. 4-1 on page 7.
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. 5-1 and Fig. 5-2).
– For distance B between the magnet and the BTL and
for the center offset C (see Fig. 5-1 and Fig. 5-2) the
following values must be maintained:
Magnet type
BTL6-A-3800-2
BTL6-A-3801-2
The selected distance must remain constant over the entire measuring
1)
length.
For optimal measurement results: 6...8 mm
2)
Tab. 5-1: Distance and offset for magnets (see Fig. 5-1 and Fig. 5-2)
– When using multiple magnets a minimum separation of
65 mm must be maintained between them (see
Fig. 5-3).

The BTL is installed on a flat surface of the machine using
mounting clamps or cuffs (available accessories). Any
orientation is permitted. Note the recommended spacing
for the location of clamps or cuffs (see Fig. 4-1 on
page 7).
1. Slide BTL into the mounting clamps or cuffs.
2. Align BTL slot in the direction of the magnet(s)!
3. Attach the BTL to the base (tighten screws in clamps
or cuffs to max. 4 Nm tightening torque).
4. Install the magnet (accessory).
5. Check orientation of the BTL. If the groove does not
point in the direction of the magnet, loosen the
mounting screws and repeat steps 2 to 3.
