About ELMI-Elektronik & SBE
ELMI-Elektronik GmbH develops and manufactures explosion-proof electrical equipment for mining machinery and mining installations, in particular electronic modules for use in hazardous areas of the mining, chemical and oil industries. The product range includes measuring systems such as two-roller belt scales (dLS 2000 BBG), bulk density measuring systems (dLS 2000 BDM) using laser and weighing technology, laser scanners for roadheaders (TSM scanner), metal search and monitoring devices, Ex-protected network cameras as well as temperature and level monitors for hydraulic power units. In addition to manufacturing electronic modules, the company offers design, development, ATEX certifications, process visualization into local networks and custom manufacturing on request. Mechanical components such as roller chairs are CNC-machined; housings and structures are made predominantly of (acid-resistant) CrNi stainless steel and steel. The company is based in Gummersbach-Vollmerhausen and brings over 30 years of experience in electronics; customers and project partners have included Ruhrkohle AG (RAG), Sandvik Mining & Construction and the Fraunhofer IML.

Materials & Processes
Stainless steel (CrNi)
Used for the flameproof enclosures of the Ex-protected network camera and for the speed sensors.
Acid-resistant stainless steel
Used for maintenance-free temperature and level monitors (STN-Ex[ia]) in hazardous areas.
Fiber optic cable Multimode 50/125 µm / 62.5/125 µm
Fiber type for fault-tolerant fiber optic Ethernet and Profibus rings of the data evaluation units.
Fiber optic cable Singlemode 9/125 µm
Enables long ranges (up to 40 km) for process data transmission via fiber optic ring.
