sensitron SMART3G-D3 Gas Detector
The SMART3G-D3 gas detector is an explosion-proof device designed to meet industrial requirements. It can be installed in ATEX Zone 2 and, when equipped with a dust adapter, in Zone 22. The device features a sensing element placed in the stainless steel head with a 47.5 mm diameter. The infrared sensors used for flammable and refrigerant gas detection are poison-free, highly accurate, and have a long lifetime. The gas detector has a power supply of 12-24 Vdc and a standard 4-20 mA 3-wires output and three relays. It can also be equipped with serial RS485 communication as an option. The enclosure dimensions are 106 x 160 x 81 mm, and it has a M20 cable gland on the upper side. The SMART3G-D3 features a 7-segment display for real-time concentration visualization and Hall effect sensors for non-intrusive field calibration. The gas detector is SIL2 hardware and SIL3 software certified, and with a redundant system, the hardware becomes SIL3. The device is pending certification but can be ATEX marked as follows: 0722 II 3G Ex db ec nC IIC T5 Gb or 0722 when equipped with a dust adapter.
Product Usage Instructions
The SMART3G-D3 gas detector is designed for use in industrial areas and can be installed in ATEX Zone 2 and, when equipped with a dust adapter, in Zone 22. To use the device:
- Ensure that the power supply is connected to the device correctly. The gas detector has a power supply of 12-24 Vdc.
- Connect the output wires and relays as required. The device has a standard 4-20 mA 3-wires output and three relays. Optionally, it can be equipped with serial RS485 communication.
- Install the device in the desired location using the M20 cable gland on the upper side of the enclosure. The enclosure dimensions are 106 x 160 x 81 mm.
- Turn on the device and monitor the 7-segment display for real-time concentration visualization and Hall effect sensors for non-intrusive field calibration.
The SMART3G-D3 gas detector is SIL2 hardware and SIL3 software certified, and with a redundant system, the hardware becomes SIL3. The device is pending certification but can be ATEX marked as follows: 0722 II 3G Ex db ec nC IIC T5 Gb or 0722 when equipped with a dust adapter.
