The Patol 5000 series of infrared flame sensors is designed to protect establishments and systems where a movement of materials with a potential fire hazard is a routine occurrence, such as within the Power Generation, Coal Mining, Process Plant and Road / Rail Terminals industries.

A 5710/5710SS Sensor employs enhanced infrared monitoring technology that enables the detection of fire initiating materials, whilst they are being transported, and before they have reached a flame condition. The 5710 is ATEX/IECEx approved to be installed in hazardous areas and offers an air purged system for dusty environments.

Technical information

The Sensor is located above the materials transit path (e.g. conveyor) by means of the adjustable mounting bracket and aligned such that the monitored hazard passes through the unit’s field of view. The height and angle of the sensor determine the width of the monitored path.

The 5710 / 5710SS Sensor case is equipped with a 10mm hose fitting for connection of a compressed air supply. This is required such that a positive air pressure is maintained around the unit’s sensor “windows”.

There is a continuous air flow from the optical path visor which stops dust settling on the sensor ‘glazed’ optical aperture.

The air purging is essential in dusty environments such as coal conveyors, and is recommended in even relatively clean applications.
