1 Safety instructions

Use in accordance with the regulations

Displacement transducers of the WA type series are suitable for all situations

where there are strict ruggedness and accuracy requirements, such as in

research, development and industrial applications. Use for any additional

purpose shall be deemed to be not in accordance with the regulations.

In the interests of safety, the transducer should only be operated as described

in the Mounting Instructions. It is also essential to observe the appropriate legal

and safety regulations for the application concerned during use. The same

applies to the use of accessories.

The transducer is not a safety element within the meaning of its use as

intended. Proper and safe operation of this transducer requires proper

transportation, correct storage, assembly and mounting and careful operation

and maintenance.

General dangers due to non‐observance of the safety instructions

The WA displacement transducer corresponds to the state of the art and is

fail‐safe.

The transducers can give rise to residual dangers if they are inappropriately

installed and operated by untrained personnel.

Everyone involved with the installation, commissioning, maintenance or repair

of a displacement transducer must have read and understood the Mounting

Instructions and in particular the technical safety instructions.

Residual dangers

The scope of supply and performance of the transducer covers only a small

area of displacement measurement technique. In addition, equipment planners,

installers and operators should plan, implement and respond to the safety

engineering considerations of displacement measurement technique in such a

way as to minimize residual dangers. Prevailing regulations must be complied

with at all times. There must be reference to the residual dangers connected

with displacement measurement technique

In these mounting instructions residual dangers are pointed out using the

following symbols:

Symbol Significance

CAUTION This marking warns of a potentially dangerous

situation in which failure to comply with safety

requirements can result in slight or moderate physical

injury.

Notice This marking draws your attention to a situation in

which failure to comply with safety requirements can

lead to damage to property.

Emphasis

See….

Italics are used to emphasize and highlight text and

references to other chapters and external documents.

CE mark

The CE mark enables the manufacturer to guarantee that the

product complies with the requirements of the relevant EC

directives (the Declaration of Conformity can be found at

http://www.hbm.com/HBMdoc).

Conversions and modifications

The transducer must not be modified from the design or safety engineering

point of view except with our express agreement. Any modification shall

exclude all liability on our part for any damage resulting therefrom.

Qualified personnel

This instrument is only to be installed by qualified personnel strictly in

accordance with the technical data and with the safety rules and regulations

which follow. It is also essential to observe the appropriate legal and safety

regulations for the application concerned. The same applies to the use of

accessories.

Qualified personnel means persons entrusted with the installation, fitting,

commissioning and operation of the product who possess the appropriate

qualifications for their function.

Accident prevention

The relevant accident prevention regulations of the trade safety associations

must be taken into account.

Introduction

WA… A00546_11_YI0_01 HBM: public 7

2 Introduction

HBM's WA displacement transducers are particularly well suited for use with all

applications requiring a high degree of durability and precision, such as

research, development and industry.

To provide documentary evidence of quality, a separate test report containing

the test data is included in the list of components supplied with the product.

All versions

Accuracy class options 0.2 or 0.1 are available for the transducers. An indi

vidual transducer characteristic is also supplied for both these accuracy

classes, as a test report. This documents the linearity error (including hyster

esis).

Probe version

Their external structure allows the displacement probes to be used like com

parators. They are distinguished by excellent resolution and accurate reprodu

cibility. The measuring element with the probe tip that is screwed into the probe

pin can be replaced with other measuring elements conforming to DIN 878

when required.

Displacement transducers can detect the displacement of measurement

objects occurring in the transducer axis direction. It is permissible to have

motion components perpendicular to the axis, if they do not exert any notice

able lateral force on the probe tip. This means that it is also possible to mea

sure irregularities, differences in thickness or ovalities on rolling or rotating

objects. It is also an advantage to use the transducers for high-precision mea

surements of the lengths and thickness differences of series of measurement

objects.

Mounting

8A00546_11_YI0_01 HBM: public WA…

3 Mounting

All versions

The transducers can be clamped at the enclosure tube. But the best mounting

position is in the center of the transducer. The mounting blocks shown on page

28 can be obtained from HBM for a diameter of 12 mm.

The transducer axis must point in exactly the same direction as the displace

ment, moving components or change in length to be measured. They can

occupy any position in the space. It can be an advantage to only finally clamp

the transducer in conjunction with adjusting the zero position and the zero bal

ance.

Probe version Standard and High temperature

Transducers also have a cylindrical shaft diameter corresponding to fit 8h6 of

the standard for comparators, which allows them to be held in all clamping

devices and measuring systems designed for comparators. If under rough con

ditions, there are significant contamination and deposits on the probe pin, then

this must be cleaned at regular intervals with a lint-free cloth and, if necessary,

gently wetted with a low-viscosity, thermally stable oil. Make sure that the sur

face of the probe pin is intact.

The probe pins of the displacement transducer are conditionally corrosion-

proof. The transducers have been designed for industrial applications.

In humid environments, the probe versions require cleaning and oiling at regu

lar intervals. If there is surface rust, the probe pin can be cleaned using steel

wool or fine emery cloth and subsequently greased.

Using the transducers in humid and at the same time cold environments is not

recommended. Frosting and icing can influence the measuring system and

lead to errors. If these conditions occur the transducers have to be cleaned

constantly or actions to prevent the conditions have to be taken.

Probe version Low temperature

Transducers also have a cylindrical shaft diameter corresponding to fit 8h6 of

the standard for comparators, which allows them to be held in all clamping

devices and measuring systems designed for comparators. If under rough con

ditions, there are significant contamination and deposits on the probe pin, then
