Company profile

Business divisions

Since 1981 we develop and manufacture high-quality temperature sensors for plastic and rubber extruders as well as rubber mixers. Our sensors are suitable for measuring melt and mass temperature, being installed at production sites of leading plastic and tire manufacturers. Moreover, our sensors have become industry standard for various manufacturers of industry plants.


In 1981 BBL was founded as a split-off company from the Institute of Plastics Processing (IKV) at RWTH Aachen University (Rheinisch-Westfälische Technische Hochschule Aachen) by Dipl.-Ing. T. Binnenkade , Dipl.-Ing. Bergweiler, and Prof. Dr.-Ing. J. Lutterbeck and built up in close cooperation with several industry partners. After 1983 the company was owned and successfully managed by Mr. T. Binnenkade for 36 years. In 2020 Dr. rer. nat. L. Binnenkade succeeded the family business as managing director in 2nd generation. Currently, we are happy to celebrate our 40-year jubilee!


The industry and technology region of Aachen offers BBL an attractive location with regard to industrial and academic collaborations, availability of highly qualified employees, short supply chains, and not at least the centered geographic location in Europe. Moreover, the presence of RTWH Aachen University plays a key role for BBL, since most of our employees have a RTWH background.



We take our responsibility seriously for an eco-compatible and CO2-neutral industry. You receive our goods in sustainable packaging made of recycled and fully degradable materials (wastepaper). This facilitates its disposal and saves valuable resources! Moreover, we use CO2-neutral shipment services and our products are manufactured with 100% green electricity.

Projects and perspectives

At BBL we are maintaining a healthy balance between long-term experience and proven processes on the one hand – and innovations and new developments on the other hand. Currently, we focus on digitalization of internal processes and development of new sensor variants for modern plastic- and rubber industry applications.
