The SMART3G-D2 detector is suitable for installation in industrial areas and ATEX zones; thanks to the explosion-proof case it can be installed in zone 1 and, if equipped with the dust adapter, in zone 21.

The sensitive element is housed in the stainless steel head. For the detection of flammable substances the catalytic sensor is used, which combines excellent linearity up to 100% LFL with fast response times.

The detector has a 12-24 Vdc power supply, at the output it has a 4-20 mA signal and three relay. RS485 serial communication can be added as an option.

The case is made of aluminum with a total size of 145 x 187 x 108 mm. Everyone the inlets are threaded with 3/4” NPT thread. The SMART3G-D2 is equipped with a 7-segment display to view concentration in real time and sensors such as Hall effect for non-intrusive field calibration.
