GERMANY • BST ProControl, a subsidiary of BST eltromat International, announced it is expanding its sensor offerings for layer thickness and basis weight measurement with a new highlight for K 2016, the new PC16S-wave transmission sensor. The company will premiere the sensor at its booth in Hall 10, Stand E46.

The sensor does not work with ionizing electromagnetic waves, therefore, neither its operation nor its transport and disposal require national or international permits. Thanks to its EMC characteristics, the PC16S-wave guarantees smooth operation and fulfills all legal requirements, the company said. With its touch-free absorption measurement procedure in transmission, it measures polymer-based monofilms. 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.


The PC16S-wave offers some characteristics that offer help when measuring polymer-based monofilms. That is how with this transmission sensor, among other things, materials can also be measured if large amounts of fillers were added to the polymer in production as a colorant. For instance, white films are frequently filled with titanium dioxide 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, the company said.

In comparison with sensors with ionizing radiation, the PC16S-wave achieves high measurement accuracy of up to 0.05 g / m². In addition, the innovative sensor covers a large measurement area of up to 2,000 g / m². And because its measurement method is based on non-ionizing technology, with the PC16S-wave, the costs for radiation protection that come with traditional transmission sensors are gone.

The company said it can be adapted for various applications and outfitted with the respective necessary components for these tasks. Even with service cases, the modular construction, in combination with technical innovations, almost guarantees a high availability of the new transmission sensor. Therefore, the PC16S-wave has a clamping device for mounting the sensor and a changing device for measurement windows. A quick-change mechanism for the measurement window was included, because measurement windows are typically made of thin plastic films that can tear or get dirty. In addition, the emitter module, including the transmitter, can be changed in about five minutes. The exchange of the complete unit takes five minutes. All components of the new transmission sensor are accessible, which simplifies its replacement and 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 Siemens. Additional advantages of the new transmission sensor, the company said, are its compact construction, the possibility of combining it with other types of sensors, and the ease of integrating it into existing production systems.
