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.
