All active protection systems require a range of sensors to actuate them. For fire and explosion protection systems the principle sensors are CO monitor, flame and spark detection, break wire and pressure detection.
The Atex CO detection system uses advanced carbon monoxide (CO) sensors to detect early stages of powder combustion before a fire or explosion can be ignited. This allows the problem to be resolved either manually or automatically, reducing fire and explosion protection costs.
The Spark Detection and Extinguishing System from Atex is an effective and economical detection method for ignition sources in transit. It prevents explosions in attached vessels by quenching the spark within the ductwork.
Assume you have a bag filter in the middle of the plant which cannot be vented. You need a slam shut valve in the inlet to prevent over pressure back down the duct and suppression on the filter to extinguish the explosion. These will require the pressure sensor PXD.
The milk dryer has a problem with exothermic build up resulting in glowing nests. Apply an ATEX CO monitor to snese CO alarm, shutdown the dryer or actuate a fire extinguishing system.
If you are milling timber and blowing it into a silo you do not want sparks or flame reaching the silo from entrapped material. Then apply a spark detection system.
