Representation and evalu-
ation is carried out by the
software’s client/server structure,
allowing users to access and ob-
tain relevant data.
The performance and quality of the whole data acqui-
sition system is determined by
measurement. Each
application requires the ideal sensor for the job, and for
this reason we offer several sensors – according to spe-
ci cation and area of application – for identical measur-
ing categories. While a customer, for example, implicitly
requires sensors in a steel housing, another application
might necessitate the need for a differential pressure sen-
sor with display. Due to our experience in various projects
we are not only able to recom-
mend, when it comes to sensors,
the best possible solution for each
application to our customers, but
we also possess a variety of alter-
natives so that each user can nd
the ideal product.
Data storage naturally takes
place in the central computer whe-
re data is collected at its collection
point in real time. What happens
if the system crashes? In cases of
maximum data security we have
integrated data logger modules
in the measurement chain. These
are situ ated between the sensor
and the central computer and represent a type of “Ham-
mock”. If the central computer does not receive all the
data, then the data can be read “of ine” and transferred
from the temporary storage devices (data loggers).
Nowadays modern data logging systems are independent
of measurement rates, or rather measurement clocks.
The data loggers establish an average value per sensor
according to the user’s requirements. With particle sen-
sors this is the total sum per time unit.
In industry, data
transfer is sent analogically to a com-
puter in the network. Due to the technical connection
with the IP Network, data recording sites each receive an
IP address and are linked by means of existing network
architecture.
Qualifi cation completes the successful system imple-
mentation procedure; calibration ensures an error-free
and long-term precise operation. In summary, the best
solution is based on two conditions: the rst of which
is the complete information of the customer’s require-
ments, the other being a exible system representing
the customer’s demands. For more detailed information
concerning our procedures and what measurements you
can yield, please consult our technical description. At the
same time we provide a long-term
traceability of processes.
Today’s industrial data acquisition generally takes place in real time. The conditions and process
environments of measured values regarding room climate change slowly, but are, nevertheless,
permanent. Therefore, modern data recording systems that are implemented in this industry
have to be reliable like Lufft products. Our products feature the following characteristics:
modular design, a fl exible and expandable sensor archive, freely programmable representation
of measured values, as well as a monitoring system that is precisely tailored to the respective re-
quirements and reacts as quickly as possible to potential nonconformities by setting off an alarm.
For many pharmaceutical and
clean room applications the most
important link in the chain is the
alarm. Ultimately, it is imperati-
ve to act immediately to any pos-
sible deviations and take approp-
riate action.
It is essential, for example, that processes such as “long-
term stability tests” or clean room production be put right
straight away if an error in the process chain arises.
