LOGISTICS ! ............A definition of “the handling of an operation involving movement of labour and / or materials”. The term more associated by many, with road / rail / air transportation from supplier to consumer, but equally as relevant in the context of material movement as an integral part of a production process .
Without the un-interrupted movement of such materials – industries “life blood”- negative financial consequences will ultimately be felt by producer and consumer alike. One of the greatest risks to this material transportation has to be – FIRE!
Coal fired Power Generation Plants and Mining industries, regularly report fires on their conveyor systems. Investigations have proven that in the majority of events, the cause of the fire was NOT from already ignited material being loaded onto and transported by the conveyor -as many may have originally believed – but due to friction between belt support roller bearings and material that had spilled from the conveyor belt…..ie.. an undetected overheat condition which was allowed to progress to a combustion stage.
DIGITAL linear heat detection, by monitoring operating temperatures at the exact point of risk, offer end users the ability to detect the overheat condition and signal an alarm. Thereby allowing local action to be taken to prevent progression to a fire stage, and in many cases removing the need for costly replacement of conveyor system hardware.
The pre-specified / pre-selected alarm temperature rating of an installed digital linear heat detection system, is not dependant upon how much of the length of heat sensitive cable is exposed, constant system sensitivity therefore being assured . Nor is any complicated system set up, installation, commissioning, calibration or special site personnel training required – unlike some competitive linear detection systems. Integration of digital linear detection with central fire control systems is also simpler – being achieved in many installations without the need for any special interface unit.
An alarm location identification feature can be provided (via dedicated interface ) by the digital linear detection system. This proving invaluable to many end users because of the lack of visible flame in an overheat alarm situation!

Where additional protection is required for monitoring and detection of glowing embers along a moving belt , and / or at conveyor material loading / transfer points , our FLAME detector may be specified .
