Description

The SMART 3G-D2 is a high-performance, SIL2 certified fixed gas detector designed for a wide range of industrial applications. Built to withstand harsh and hazardous environments, it offers reliable detection of toxic, flammable, and refrigerant gases, making it suitable for use in classified areas such as petrochemical plants, refineries, and processing facilities.

One of the standout features of the SMART 3G-D2 is its non-intrusive calibration. This function enables safe and easy calibration via Hall-effect switches, eliminating the need to open the device. This makes it ideal for use in difficult or hazardous locations, where traditional calibration methods may be impractical or unsafe. The non-intrusive design ensures both convenience and accuracy, reducing maintenance time and minimising downtime.

The detector is equipped with a 4-digit backlit display that clearly shows the gas concentration reading, even in low-light conditions. A 5-mode status LED and a high-visibility multi-colour LED light ring provide immediate visual feedback on the detector’s operational status, enhancing onsite safety by making status recognition quick and intuitive.

The SMART 3G-D2 offers detection capabilities for over 50 different gases, including a wide range of flammable, toxic, and refrigerant gases. This flexibility allows the device to be tailored to various industrial needs, ensuring comprehensive protection against potentially dangerous gas leaks.

In terms of safety assurance, the SMART 3G-D2 meets SIL2 certification for hardware and SIL3 certification for software. When used in a redundant system configuration, the hardware can also meet SIL3 requirements. This high level of certification underscores the detector’s reliability in safety-critical applications, helping organisations maintain compliance with stringent safety standards.

Overall, the SMART 3G-D2 is a robust, feature-rich solution for fixed gas detection, offering advanced functionality, flexible gas monitoring options, and industry-recognised safety certifications.
