Infrared Transit Heat and Flame Sensors
Detection of heat in moving product on conveyor systems
Many goods carried on conveyor systems are highly combustible and have the potential to self-ignite. If they combust upon an unprotected belt, the likelihood is that the system will enable fire to spread into the holding hoppers, blending, crushing areas of the plant.
Patol produce IECEx/ATEX approved infra-red transit heat sensors for hazardous areas designed to detect high energy emissions from abnormal 0but relatively low temperature product. In addition to detection at belt loading points, IR sensors can be installed within a water spray zone prior to the conveyor system discharge points to silos and hoppers.
Infrared Transit Heat Sensors Monitor and detect in the presence of ambient light, ‘hot spots’ or embers at temperatures as low as 100˚C on conveyor systems travelling at speeds of between 0.5 and 6 metres per second.
Infrared Transit Flame Sensors Monitor and detect in the presence of ambient light, small flames at temperatures over 240˚C on conveyor systems travelling at speeds of between 0.5 and 6 metres per second.
General information
Infrared Transit Heat Sensors
- Coal and biomass
Coal products and dust have the ability to self combust under certain conditions. Biomass is particularly prone as it can be composed of a multitude of unknown refuse items.
- Waste recycling
Mixed recyclable waste, collected, sorted, stockpiled and processed from highly combustible materials is highly susceptible to potential ignition from processing machinery.
Infrared Transit Flame Sensors
- Food manufacture
Pop corn, crisps or cornflakes has the potential to ignite. Sensors located above the conveyor monitor the food product as it leaves a fryer, oven or dryer.
