GSME Hotspot Detector
Plants that are at risk of explosive dust must frequently be provided with explosion protection measures since ignition sources are often unavoidable. In addition to electrostatic phenomena and mechanically generated functions, the most frequent ignition sources particularly include glowing embers, open flames and hot surfaces. Alongside grounding monitoring systems and spark extinguishing systems, the GSME detector series make an enormous contribution to increasing explosion safety. The GSME series have been developed for the early identification of combustion reactions and thermal events, which can ultimately be ignition sources for explosions.

Application
The compact GSME pyrolysis gas detector is specifically tailored for the early detection of hot surfaces and fire in dust-handling equipment, such as silos, dryers, mills, conveyors or dust collectors.
Mechanism
The well-proven multi-criteria technology on a semiconductor base already enables foolproof early detection by the GSME of all types of concealed and open glowing embers and smouldering fires in the emergent phase. The sensor elements of the detectors are protected from dust and moisture with the unique diffusion filter technology. The GSME is also protected from the penetration of moisture and dust due to its robust design. It is specifically designed for use in areas up to Zone 20 and tested in accordance with ATEX and IECEx.
