The GDS850 is an ATEX-certified fixed industrial gas detector developed and manufactured in Italy by Tecnocontrol for the continuous monitoring of combustible gases in high-risk industrial environments. It has been designed to deliver maximum operational reliability, outstanding functional safety, and easy maintenance, even in the most demanding applications.
Certified according to ATEX, IECEx, SIL2 Hardware, SIL3 Software, and EN 60079-29-1 Performance, the GDS850 is the ideal solution for chemical and petrochemical plants, refineries, storage terminals, Oil & Gas facilities, power generation plants, and any hazardous area where reliable, standards-compliant gas detection is essential.
Accurate Detection of Combustible Gases
The GDS850 fixed ATEX gas detector is designed to continuously monitor a wide range of combustible and flammable gases, helping to prevent potentially hazardous situations that could threaten personnel, equipment, and infrastructure.
Its high measurement accuracy and fast response time enable early detection of gas leaks or abnormal conditions, allowing connected safety systems to react immediately.
Compliance with EN 60079-29-1 ensures certified detection performance, providing dependable operation even under the harshest industrial conditions.
ATEX, IECEx and SIL Functional Safety Certifications
When designing an industrial gas detection system, ATEX certification alone is often not sufficient.
The GDS850 combines installation safety with certified detection reliability through the following approvals:
- ATEX Certification
- IECEx Certification
- SIL2 Hardware
- SIL3 Software
- EN 60079-29-1 Performance Certification
These certifications make the GDS850 particularly suitable for safety-critical installations and applications where continuous operation and high functional integrity are essential.
Easy Installation and Maximum Flexibility
One of the key advantages appreciated by installers is the detector's exceptional wiring flexibility.
The GDS850 features four dedicated cable entries, providing greater freedom during installation and simplifying integration into both new and existing gas detection systems. This design reduces installation time while making future maintenance and system expansions significantly easier.
Its rugged industrial enclosure, rated IP66, provides excellent protection against dust, water, and harsh environmental conditions, making the detector suitable for demanding outdoor and industrial applications.
Integrated Bluetooth for Simplified Maintenance
The GDS850 introduces a smarter approach to gas detection maintenance.
Thanks to its integrated Bluetooth connectivity and dedicated mobile App, many diagnostic and configuration tasks can be performed without opening the flameproof enclosure. Operators can check sensor status, monitor remaining sensor life, review operating parameters, and verify detector performance directly from a smartphone or tablet.
This significantly reduces maintenance time while simplifying routine inspection procedures.
Integrated Display and Advanced Diagnostics
The GDS850 version with integrated display provides real-time indication of detected gas concentration together with the detector's operating status.
Operators can instantly view alarm, fault, or maintenance conditions, enabling faster decision-making and improved plant safety. The intuitive interface and high-visibility status indicators contribute to more efficient system management and quicker response to abnormal situations.
Industrial Communication and System Integration
The GDS850 SIL2 industrial gas detector has been designed for seamless integration into modern industrial automation and safety systems.
Multiple communication options allow easy connection to:
- Gas detection control panels
- Industrial PLCs
- SCADA systems
- Remote monitoring platforms
- Safety management systems
Standard 4–20 mA and Modbus RS485 outputs ensure straightforward integration into both new installations and retrofit projects.
Replaceable Sensor Cartridge
To minimize maintenance costs and downtime, the GDS850 features a plug-in replaceable sensor cartridge with an integrated socket connection.
The sensor can be replaced quickly and easily without complex servicing procedures, reducing plant downtime and ensuring maximum operational continuity.
