In the course of four research and development projects, transducers for the central monitoring of underground operations were developed and tested along with the associated data collection and transmission equipment. Close cooperation with companies and improvement of the electrical and mechanical construction during equipment testing were the main aspects of the work. At the same time, technical support was given in the establishment and introduction of analog and digital interfaces for German hard coal mining. A measurement system was thus developed, with sensors to monitor: - pressures in gaseous and liquid media; - mechanical stresses; - angles of rotation; - temperatures in different media and at parts of machines; - electrical values. The measurement system comprises data collection equipment, either connected in series via a bus system to wider remote control and transmission systems, or capable of operating independently. As regards its explosion proof characteristics, its essential components rate as inherently safe, and the system has thus been approved for use underground.
