30 Extrusion International 1/2017 MEASUREMENT PC16S ® -wave transmission sensor www.bst-procontrol.com 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 thebrandnewPC16S ® -wave transmission sensor, BST ProControl, a subsidiary of BST eltromat International, is expanding its extensive sensor offerings for layer thickness andbasisweightmeasurement. The innovative sensorwas celebratingitsworldpremiereatK2016,anddoesnotwork 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 The PC16S ® -wave transmission sensor from BST ProControl works with an innovative sensor technology based on non-ionizing electromagnetic waves and stands out due to its outstanding performance as well as flexibility
