2.1 Intended use

The BTL7 Micropulse Transducer, 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 transducer or non-approved use are not

permitted and will result in the loss of warranty and liability

claims against the manufacturer.

2.2 General safety notes for the position

measuring system

Installation and startup may only be performed by

trained specialists with basic electrical knowledge.

Qualified personnel are those who can recognize

possible hazards and institute the appropriate safety

measures due to their professional training, knowledge,

and experience as well as their understanding of the

relevant conditions pertaining to the work to be done.

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 position measuring system will not result in

hazards to persons or equipment.

If defects and unresolvable faults occur in the transducer, it

should be taken out of service and secured against

unauthorized use.

2.3 Explanationof the warnings

Always observe the warnings in these instructions and the

measures described to avoid hazards.

The warnings used here contain various signal words and

are structured as follows:

SIGNAL WORD

Hazard type and source

Consequences if not complied with

►Measures to avoid hazards

The individual signal words mean:

NOTICE

Identifies a hazard that could damage or destroy the

product.

DANGER

The general warning symbol in conjunction with the

signal word DANGER identifies a hazard which, if not

avoided, will certainly result in death or serious

injury.

2.4 Disposal

►Observe the national regulations for disposal.

3.1 Construction

Electrical connection: The electrical connection is made

via a cable or a connector (see Type code breakdown on

page21).

Housing: Aluminum housing containing the waveguide

and processing electronics.

Magnet: Defines the position to be measured on the

waveguide. Magnets are available in various models and

must be ordered separately (see Accessories on

page18).

Nominal length: To optimally adapt the transducer to the

application, nominal lengths from 50mm to 7620mm are

available.

3Construction and function (continued)

3.2 Function

The BTL7 transducer contains the waveguide which is

protected by an aluminum housing. A magnet is moved

along the waveguide. This magnet is connected to the

system part whose position is to be determined.

The magnet defines the position to be measured on the

waveguide.

An internally generated INIT pulse interacts with the

magnetic field of the magnet to generate a torsional wave

in the waveguide which propagates at ultrasonic speed.

The component of the torsional wave which arrives at the

end of the waveguide is absorbed in the damping zone to

prevent reflection. The component of the torsional wave

which arrives at the beginning of the waveguide is

converted by a coil into an electrical signal. The travel time

of the wave is used to calculate the position. Depending

on the version, this information is made available as a

voltage or current with rising or falling gradient.

The following functions can be selected for the output

values:

– Position

– Speed (with or without leading sign)

The entire function scope can only be

configured with the PC software "Micropulse

Configuration Tool". To do this, the USB

communication box must be connected (see

Accessories on page18).

4.1 Installing the transducer

NOTICE

Improper installation

Improper installation can compromise the function of the

transducer and result in damage.

►For this reason, ensure that no strong electrical or

magnetic ﬁelds are present in the immediate vicinity

of the transducer.

►The recommended spacing for the installation must

be strictly observed.

Any orientation is permitted. Mount the transducer on a

level surface of the machine using the provided mounting

clamps and cylinder-head screws. A sufficient number of

mounting clamps is supplied.

In order to avoid the development of resonant

frequences from vibration loads, we

recommend arranging the mounting clamps at

irregular intervals.

The transducer is electrically isolated from the machine

with the supplied insulating bushes (see Fig. 3-1).

1. Guide the transducer into the mounting clamps.

2. Attach transducer to the base using mounting screws

(tighten screws in the clamps with a max.2Nm).

3. Insert magnet (accessories).

The micropulse transducer in profile housing is

suitable both for floating, i.e.non-contacting

magnets (see Fig. 4-4 toFig. 4-8) and for

captive magnets (see Fig. 4-1 to Fig. 4-3).

4.2 Captive magnets

The following must be observed when installing the

magnet:

– Avoid lateral forces.

– Connect the magnet to the machine member with a

joint rod (see Accessories on page18).

4.3 Floating magnets

The following must be observed when installing the

magnet:

– To ensure the accuracy of the position measuring

system, 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 track

parallel to the transducer.

– Ensure that the distance A between parts made of

magnetizable material and the magnet is at least

10mm (see Fig. 4-4 toFig. 4-8).

– Maintain the following values for distance B between

the magnet and transducer and for center offsetC (see

Fig. 4-4 toFig. 4-8):

Type of magnet DistanceB1) OffsetC

BTL5-P-3800-2 0.1…4mm ±2mm

BTL6-A-3801-2 4…8mm2) ±5mm

2) The selected distance must stay constant over the entire measuring length.

1) For optimum measurement results, a distanceB of 6 to 8mm is

recommended.
