The Sensitron SMART3G-C3 gas detector is designed to meet industrial requirements. Its enclosure is explosion-proof and can be installed in ATEX Zone 2 and, when equipped with a dust adapter, Zone 22.
The sensing element is placed in the stainless steel head with a 40 mm diameter.
The infrared sensors employed for flammable and refrigerant gas detection are poison-free, have high accuracy, and have a long lifetime.
The gas detector has a 12-24 Vdc power supply and a standard 4-20 mA 3-wire output. Optionally, the SMART3G-C3 can be equipped with serial RS485 communication and a 1 or 3 relay board.
The enclosure measures 106 x 160 x 62 mm and has an M20 cable gland on the upper side.

| STS/CKD+ | Enhanced calibration keypad with 7-digit display and SD-CARD slot. It can be connected to all SMART detectors to adjust the Zero, Span and 4-20 mA values. Via the SD-CARD, it is also possible to update the detector’s firmware (a feature not enabled on old SMART3G and NC detector) |
| STS/CKD-OLED | Enhanced calibration keypad with OLED display and SD-CARD slot. It can be connected to all SMART detectors to adjust the Zero, Span and 4-20 mA values. This version offers enhanced features like: – visualisation of the instantaneous concentration in graphic format; – possibility to monitor the detector trend and download the data stored in the SD-CARD – detector’s firmware update via SD-CARD (feature not enabled on old SMART3G and NC detector) |
| STS1REL | 1-Relay card for SMART3G. Relay at 12÷24V |
| STS3REL | 3-Relay card for SMART3G. Relay at 12÷24V |
