Description

The SMART 3G-C3 is a high-performance fixed gas detector designed for demanding industrial environments. Certified to SIL2 standards, it offers reliable and accurate monitoring of toxic, flammable, and refrigerant gases across a wide range of hazardous and classified areas. Whether deployed in refineries, chemical plants, or manufacturing facilities, this detector provides robust gas detection and safety assurance where it matters most. Its rugged construction and proven technology make it an ideal solution for challenging applications where precision and reliability are critical.

Comprehensive Gas Detection Capabilities

One of the key strengths of the SMART 3G-C3 is its flexibility. It supports the detection of over 50 different gases, including a wide selection of flammable, toxic, and refrigerant options. This broad compatibility ensures it can be tailored to meet the specific safety needs of virtually any industrial application. Whether you need to monitor ammonia, methane, carbon monoxide, or specialised refrigerants, the SMART 3G-C3 can be configured with the appropriate sensor to provide accurate and timely detection.

Ongoing Self-Diagnosis and Optional Modbus Communication

To enhance operational reliability, the SMART 3G-C3 features continuous self-diagnosis, allowing the device to monitor its own functionality in real time. This proactive system alerts users to potential faults or maintenance needs before they can affect performance, helping to minimise downtime and ensure consistent protection. In addition, the device offers an optional RS485 interface, enabling seamless integration with Modbus communication systems. This makes it easy to connect the detector to existing control panels or supervisory systems, streamlining data sharing and system management across large or complex installations.

High-Level SIL Certification for Enhanced Safety

Safety Integrity Level (SIL) certification is a crucial measure of a system’s reliability and functional safety, especially in critical industrial environments. The SMART 3G-C3 is SIL2 certified in both hardware and software, ensuring it meets stringent international safety standards. For systems requiring even greater redundancy, the hardware can be configured to meet SIL3 requirements as well. This high level of certification gives operators and safety managers confidence that the SMART 3G-C3 will perform reliably when it matters most—protecting personnel, assets, and the environment from hazardous gas leaks.

FAQs
What gases can the SMART 3G-C3 detect?

The SMART 3G-C3 is capable of detecting over 50 different gases, including flammable gases (e.g., methane, propane), toxic gases (e.g., carbon monoxide, hydrogen sulphide, ammonia), and refrigerant gases (e.g., R-134a, R-404A).

Is the SMART 3G-C3 suitable for hazardous areas?

Yes, the SMART 3G-C3 is certified for use in classified and hazardous areas. It is designed to operate in environments where explosive gas atmospheres may be present.

What type of communication outputs does the SMART 3G-C3 support?

The detector features a standard 4–20mA analogue output, and also offers optional RS485 Modbus communication. This allows easy integration with modern control systems for real-time data exchange and diagnostics.

Does the SMART 3G-C3 have a self-diagnostic function?

Yes, it includes ongoing system self-diagnostics to continuously monitor the detector’s functionality. This helps identify any internal faults or calibration drift, ensuring the detector remains in optimal working condition.

How often does the SMART 3G-C3 need to be calibrated?

Calibration frequency depends on the type of gas being monitored and the environment. However, Sensitron recommends regular calibration, typically every 6 to 12 months, to maintain accuracy and compliance with safety standards.
