PC16S®-wave transmission sensor
exchange of the complete unit barely
takes five minutes. All components of
the new transmission sensor are very
easily accessible, which additionally
simplifies its replacement and further
increases system availability.
The measurement data, transferred at
a sampling rate of 100 Hz, are quickly
transferred via the Profinet protocol,
because the PC16S® -wave is equipped
with an open analysis unit from Sie-
mens. That is advantageous for many
customers because they are confident
in using the programming language
of the analysis unit, which is very wide-
spread in this market, and, in the event
that service is needed, replacement
parts are easily acquired. Ultimately, for
BST ProControl customers, both aspects
mean cost benefits. Additional advan-
tages of the new transmission sensor
are its compact construction, the pos-
sibility of combining it with other types
of sensors, and the ease of integrating
it into existing production systems.
The PC16S®-wave offers some spe-
cial characteristics that offer BST
ProControl’s customers additional
possibilities for help when measuring
polymer-based monofilms. That is how
with this transmission sensor, among
other things, materials can also bemea-
sured if large amounts of fillers were
added to the polymer in production
as a colorant. For instance, white films
are frequently filled with titanium di-
oxide and black films with soot. While
these fillers often strongly influence
the measurement results of traditional
measurement materials, such as x-ray
or infra-red technology, for example,
the influence is typically negligible with
this new transmission sensor.
In comparison with sensors with ion-
izing radiation, the PC16S®-wave
achieves extremely high measurement
accuracy of up to 0.05 g / m². In ad-
dition, the innovative sensor covers
a large measurement area of up to
2,000 g/m². And because its measure-
ment method is based on non-ionizing
technology, with the PC16S®-wave, the

with ionizing electromagnetic waves. Therefore, neither
its operation nor its transport and its disposal require
national or international permits. Thanks to itsoutstanding
EMC characteristics, the PC16S®-wave guarantees smooth
operationand fulfills all legal requirements.With its touch-
free absorption measurement procedure in transmission,
it measures polymer-based monofilms particularly quickly
and precisely. Typical examples of implementation are
the measurement of basis weights, measurements of flat
web materials, and the control of calenders and flat film
extrusion systems.
inevitable costs for radiation protection
that come with traditional transmission
sensors are gone.
In addition, its use is versatile. Thanks
to its modular construction, it can be
efficiently adapted for various applica-
tions and outfitted with the respective,
necessary components for these tasks.
Even with service cases, the modular
construction, in combination with tech-
nical innovations, guarantees a high
availability of the new transmission sen-
sor. Therefore, the PC16S®-wave has a
quick clamping device for mounting
the sensor and a quick changing device
for measurement windows, among
other things. Because measurement
windows are typically made of thin
plastic films that can tear or get dirty,
simple interchangeability was sought
after here. Thanks to the quick-change
mechanism for the measurement win-
dow, this market demand is fulfilled
in a particularly intelligent way on the
PC16S®-wave. In addition, the emitter
module, including the transmitter, can
be changed in about five minutes. The
