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 ATEX pressure eXplosion Detector PXD. This Ceramic Rate of Rise detector is modular and can be configured in PXD 1, 2 or 3 sensor and /or combinations. As a 2 out of 3 option, it has redundancy and can dramatically reduce the possibility of spurious operations. Individual Sensors can be located up to 10 meters apart to reduce mechanical impact
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.
