GSME

for storage points, extraction + filter systems for the detection of combustion gases.

Particularly plants that are at risk of explosive dust must frequently be provided with explosion protection measures, as 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.

Advantages

Explosion prevention with early detection of smouldering and developing fires.
Highest moisture and dust resistance with unique diffusion filter technology.
Approvals in accordance with ATEX and IECEx.
Comprehensive explosion safety concepts through the integration of the detectors into the REMBE^® EXKOP^® Express control unit.

Mechanism

The well-proven multi-criteria technology on a semiconductor basis 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.

Productinformation GSME

In contrast to conventional fire detection systems, the selection and positioning of special fire detectors is a particular challenge for industrial environments. The arrangement and alignment of the detectors should therefore be exclusively specified by specialist planners.
