SMART3G-C3
with infrared sensor
SMART3G-C3 gas detector is designed to meet industrial requirements; the
enclosure is explosion proof and can be installed in ATEX Zone 2 and, when
equipped with dust adapter, in Zone 22.
The sensing element is placed in the stainless steel head with 47.5 mm
diameter.
The infrared sensors employed for the flammable and refrigerant gas detection
are poison free, with high accuracy and a long lifetime.
The gas detector has a 12-24 Vdc power supply and a standard 4-20 mA 3-wires
output. Optionally, the SMART3G-C3 can be equipped with serial RS485
communication and a 1 or 3 relays board.
The enclosure has dimensions 106 x 160 x 62 mm, on the upper side there’s a
M20 cable gland.
The gas detector is certification pending and it can be ATEX marked as
follows:
0722 II 3G Ex db ec nC IIC T5 Gb
Or, when equipped with dust adapter:
0722 II 3GD Ex db ec nC IIC T5 Gb
Ex tb IIIC T100°C Db
IP65
SMART3G-C3 is SIL2 hardware and SIL3 software; with a redundant system also
the hardware is SIL3.
