Hotspot

checks the surface temperature of the processed material.

REMBE® HOTSPOT
Made in Germany
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 Hotspot detector series make an enormous contribution to increasing explosion safety. The Hotspot series have been developed for the early identification of combustion reactions and thermal events, which can ultimately be ignition sources for explosions.
Application
The Hotspot thermographic 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.

Junction box

Advantages
  • Explosion prevention with early detection of smouldering and developing fires.
  • Highest moisture and dust resistance with unique diffusion filter technology.
  • Comprehensive explosion safety concepts through the integration of the detectors into the REMBE® EXKOP® Express control system.
Funktionsweise GSME
Mechanism
Hotspots are freely parametrisable infrared camera systems in the form of detectors with integrated signal evaluation. In addition to process monitoring, they are also particularly suitable for the detection of overheating plant components and glowing embers.

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.
