Conversions and modifications
The pressure transducer must not be modified from the design or safety engineering
point of view except with our express agreement. Any modification shall exclude all liabil­
ity on our part for any damage resulting therefrom.
Qualified personnel
The pressure transducer is only to be installed and used by qualified personnel, strictly in
accordance with the specifications and with the safety rules and regulations which fol­
low. It is also essential to comply with the legal and safety requirements for the applica­
tion concerned during use. The same applies to the use of accessories.
Qualified personnel means persons entrusted with the installation, assembly, commis­
sioning and operation of the product, who possess the appropriate qualifications for their
function.
Once the pressure device has been mounted, it must be tested.
The manometers themselves are not systems that need monitoring, but if necessary,
recurrent testing can be carried out by competent personnel (bP) as per §10 of the Euro­
pean Health and Safety at Work Act (BetrSichV).
Recalibration and repair
When you send the transducer back to HBM for calibration or repair, please specify which
pressure medium is being used. It is always possible that residual medium could be
trapped in the measurement aperture. We need this information so that we can take
appropriate action and choose the correct cleaning agent, where necessary. If we do not
know the media, we may have to refuse to calibrate or repair.
Remaining dangers
The scope of supply and performance of the transducer covers only a small area of mea­
surement technology. In addition, equipment planners, installers and operators should
plan, implement and respond to the safety engineering considerations of pressure mea­
surement technology in such a way as to minimize remaining dangers. Prevailing regula­
tions must be complied with at all times. There must be reference to the remaining dan­
gers associated with pressure measurement technology.
Although the transducer is designed for maximum safety, safety engineering regulations
demand that burst protection is implemented around the transducer. This is particularly
important for frequent or dynamic loading.
The transducer must be protected against mechanical stresses or knocks. The resis­
tance of the steel of the measuring body only applies if temperatures are never allowed
to fall below or rise above the limits specified in the data sheet. If these temperature lim­
its are exceeded, in the event of fire, for example, the transducer will be unusable.
