Product Overview
The Sensitron SMART 3G D2 is a high-performance gas detector specifically designed for use in hazardous areas (ATEX Zone 1, Category 2). It is suitable for the detection of flammable gases, toxic gases, and oxygen, combining high accuracy with a robust design. With its 4-20 mA output and RS485 Modbus communication, the SMART3G-D2 is easy to integrate into existing safety systems. The detector features a replaceable sensor module, automatic self-diagnosis, and status LEDs. Its stainless steel housing makes it ideal for demanding industrial applications such as petrochemical plants, offshore installations, and power generation.
What is it?
The Sensitron SMART?3G-D2 is a high-performance gas detector specifically designed for use in hazardous environments (ATEX Zone?1, Category?2). It detects flammable gases, toxic gases, and oxygen, combining high accuracy with a robust industrial design. With its 4-20?mA output and RS-485 Modbus communication, the SMART?3G-D2 can be easily integrated into existing safety systems. Equipped with automatic self-diagnosis, status LEDs, and a replaceable sensor module in a stainless steel housing, it is ideally suited for demanding applications such as petrochemical plants, offshore facilities, and power generation.
How does it work?
The SMART?3G-D2 continuously measures gas concentrations using an advanced replaceable sensor. If preset alarm thresholds are exceeded, the system triggers visual and audible alerts and switches relay/communication outputs to activate ventilation, alarms, or PLCs. Automatic self-tests and fault messages ensure reliable operation.
What problems does it solve?
In hazardous zones, timely and reliable gas detection is critical to prevent accidents, environmental incidents, and equipment damage. The SMART?3G-D2 offers a safe, scalable, and industrial-grade solution that protects personnel and assets while supporting compliance with safety standards and regulations.
