The SMART3G-C2-LD is equipped with an infrared sensor and is designed to meet industrial requirements. The enclosure is explosion-proof and can be installed in ATEX Zone 1. It can be used in Zone 21 when fitted with a dust adapter.
The sensing element is placed in the stainless steel head with a 48 mm diameter.
The infrared sensors employed for 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, a standard 4-20 mA 3-wires output, and three relays. Optionally, the SMART3G-C2-LD can be equipped with serial RS485 communication.
The aluminium enclosure has dimensions 145 x 187 x 108 mm. The enclosure has three cable entries that are 3/4” NPT threaded. The multi-colour LED light ring assures an immediate visual indication of the detector status.
The SMART3G-C2-LD is SIL2 hardware and SIL3 software with a redundant system; the hardware is SIL3.
