IR3 Flame detector, RFD3X is efficient, compact device to detect flame / fire incidence. RFD3X works on IR3 spectrum detection technology. As it is IP67 ingress protected with IECEx, ATEX, FM certified approval, it can be install at non-hazardous atex-explosion-imageareas like electrical room, cold stores, warehouse etc, or explosion proof areas like oil rig, refinery, bottling plants, battery rooms, cracker unit.

Due to highly efficient detection and wide view angle, it ideal for flame detection for 90° horizontal and vertical view upto 60 meter distance. It can be easily integrated with analog or digital system controller / BMS / SCADA system, with its standard analog signals, digital output and digital RS485 signals. With its unique feature, it provides fault and warning signals, in case of abnormal operation.

Explosion proof or flameproof gas sensor transmitter - ATEX, Zone 1, 2 for all toxic, flammable gas, oxygen
Being stainless steel enclosed with IP67 protection, it can be install at application area, be it coal mines, offshore platform, cold stores, refinery, power plants etc
