Safety instructions
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 resid­
ual medium could be trapped in the measurement aperture. We need this infor­
mation 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 measurement technology. In addition, equipment planners, installers
and operators should plan, implement and respond to the safety engineering
considerations of pressure measurement technology in such a way as to mini­
mize remaining dangers. Prevailing regulations must be complied with at all
times. There must be reference to the remaining dangers associated with pres­
sure measurement technology.
Although the transducer is designed for maximum safety, safety engineering
regulations demand that burst protection is implemented around the trans­
ducer. This is particularly important for frequent or dynamic loading.
The transducer must be protected against mechanical stresses or knocks. The
resistance 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 limits are exceeded, in the event of fire, for example, the
transducer will be unusable.
If, during operation the zero signal changes by more than 5% (with no change
in the ambient conditions), the user should check the transducer to make sure
that it is not being overloaded (and causing the transducer characteristic to
vary).
