Quick Specs

GD2G Catalytic Fixed Gas Detectors

The GD2G Catalytic Gas Detector was developed to quickly and reliably detect flammable and explosive gases in the environment. With its economical price, the GD2G offers a budget-friendly solution that provides long-lasting and accurate measurements with regular calibration maintenance. Compliant with international standards and certified according to ATEX and IECEx regulations, the GD2G is the ideal choice for ensuring maximum safety in your industrial facilities.

Its advanced microcontroller-based smart circuit board, powered by embedded software algorithms, guarantees high-performance detection under all environmental conditions. Additionally, software optimizations tailored to your facility’s specific needs are possible.

Thanks to its digital relay outputs (NOC), the GD2G Catalytic Fixed Gas Detector can be used as a standalone unit and can be easily integrated into existing control and automation systems with its industry-standard 4-20 mA analog outputs. The detector instantly detects the presence of the target gas and responds quickly when the lower and upper alarm limits are reached. This helps to prevent potential hazards from escalating, which in turn maximizes personnel and facility safety.

Key Features:

Communication Options: Flexibility Tailored to Your Process

4-20 mA Analog Output (GD420)

  • This model does not have a relay. It connects directly to process control loops. This requires minimal field wiring and maintenance.

Optional Modbus RS-485 (GD485)

  • It enables you to digitally transfer measurement data to your central SCADA, DCS, or PLC systems and facilitates multi-device monitoring and diagnostics.

These two options allow you to seamlessly integrate your GD2G detector into your existing automation architecture, ensuring the reliable and continuous transfer of critical gas data to management.
