Magnetostrictive Linear Position Sensor – Rod Style
The CE Mark verifies that our products
meet the requirements of the current
EMC Directive.
Intended use
The BTL magnetostrictive linear position sensor, together
with a machine controller (e.g. PLC), comprises a position
measuring system. It is intended to be installed into a
machine or system and used in the industrial sector.
Flawless function in accordance with the specifications in
the technical data is ensured only when using original
Balluff accessories. Use of any other components will void
the warranty.
Opening the BTL or non-approved use are not permitted
and will result in the loss of warranty and liability claims
against the manufacturer.
General safety notes
Installation and startup may only be performed by
trained specialists.
The operator is responsible for ensuring that local safety
regulations are observed. In particular, the operator must
take steps to ensure that a defect in the BTL will not result
in hazards to persons or equipment.
If defects and unresolvable faults occur in the BTL, take it
out of service and secure against unauthorized use.

Dimensions and function
The BTL contains the waveguide which is protected by an
outer stainless steel tube (rod). A float is moved along the
waveguide. This float also rises and falls with the level of
the liquid whose position is to be determined.
The float defines the position to be measured on the
waveguide.
Ensure vertical mounting! The BTL is shown in a
horizontal position in the Figure.

Installing the BTL
NOTICE!
Interference in function
Improper installation can compromise the function of the
BTL and result in increased wear.
► Only vertical mounting from above is permitted!
► The mounting surface of the BTL must make full
contact with the supporting surface and be perfectly
sealed through the use of a seal and tri-clamp.
► Mounting must be done in a manner where the rod
cannot touch the container wall. Deflection of the
rod to the side, e.g. through flow currents, must
be prevented by a suitable, cleanable bracket or
appropriate positioning in the tank.
► Be sure that no foreign bodies can end up in the
product area.
