GX-CO2-30 Carbon Dioxide Gas Sensor

GX-CO2-30 CO₂ Sensor: Safety for Gastronomy and Technical Facilities – Precise, Robust, Compliant

In gastronomy, cold storage rooms, or technical installations with CO₂ cylinders, an invisible leak can become a deadly hazard – but with the GX-CO2-30 NDIR sensor from Elektrotechnik Schabus GmbH & Co. KG, you stay in control.

This high-precision external carbon dioxide sensor has been specifically developed for the demanding daily use in the beverage industry, breweries, and food processing environments.

With practical alarm thresholds – pre-alarm at 1.5 %vol. CO₂, main alarm at 3.0 %vol. CO₂ – it complies with beverage dispensing regulations and avoids false alarms caused by normal ambient CO₂ levels. Thanks to non-dispersive NDIR infrared technology, the GX-CO2-30 provides long-lasting, drift-free measurements, while the IP54 protection rating with a high-tech membrane keeps out splash water and dust.

Whether used as a standalone active sensor with integrated buzzer, status LEDs, and test button, or as an accessory for the GX-A1+ and GX-HS gas warning devices – the GX-CO2-30 is your reliable partner for safety, compliance, and operational continuity. Made in Germany, supplied with 6 m cable, mounting accessories, and a detailed manual – ready for immediate use.

The GX-CO2-30 technology is based on the proven NDIR principle: infrared light passes through ambient air, and the absorption at the CO₂-specific wavelength is precisely measured – without chemical reactions, without wear, and without calibration.

The result: stable measurements for years, even in humid, dusty, or temperature-fluctuating environments. The sensor operates autonomously: green LED indicates operation, yellow LED signals malfunction, red LED and loud buzzer indicate alarm.

At the same time, it transmits an analog voltage signal to the GX-HS or GX-A1+ to switch relays – for automatic ventilation, solenoid valves, or building management systems. The 6 m connection cable (3x0.14 mm²) can be extended if required: up to 20 m with 0.14 mm² or up to 50 m with 0.5 mm² cross-section.

The splash-resistant IP54 housing allows installation directly in cold rooms, beverage systems, or storage areas – cleaning with water? No problem, the sensor stays functional. The GX-CO2-30 is not fully TRGS-certified but fulfills all major requirements and provides a smart, practical solution for operators seeking safety and comfort in combination.

The GX-CO2-30 is more than a measuring instrument – it is the backbone of professional CO₂ monitoring in technical and commercial environments. In small, poorly ventilated rooms, CO₂ concentration can rise rapidly in case of leaks – the GX-CO2-30 detects this early, before health or safety limits are exceeded.

Its higher threshold values (1.5 % / 3.0 %vol.) are deliberately chosen: they ignore normal CO₂ loads from people or ventilation but react immediately to technical leaks from bottles, pipelines, or dry ice. Combined with Schabus warning devices, an intelligent safety network is created: local alarms, automatic shutdown, and remote notification.

The robust design, simple test button operation, and German workmanship make the GX-CO2-30 a worthwhile investment – preventing accidents, lowering insurance costs, and enhancing operational safety. Whether in large kitchens, wine cellars, or logistics warehouses: the GX-CO2-30 protects lives, equipment, and reputation – quietly, precisely, and uncompromisingly.

The GX-CO2-30 impresses with technical sophistication:

• NDIR technology: Drift-free, durable, precise – no calibration required.
• Practical alarm thresholds: Pre-alarm at 1.5 %vol., main alarm at 3.0 %vol. – in accordance with beverage dispensing regulations.
• Standalone & networked: Integrated buzzer, LEDs (operation/fault/alarm), test button + connection to GX-A1+/GX-HS.
• IP54 protection: Splash proof, dust resistant – with high-tech membrane for humid environments.
• Flexible installation: 6 m cable (3x0.14 mm²), 2 screws, wall plugs – extension possible up to 50 m.
• Analog control: Voltage signal triggers relays in warning devices – for ventilation, shutdown, or alarm chains.
• Made in Germany: Top quality, service, and compatibility by Elektrotechnik Schabus.

Applications: Where the GX-CO2-30 is indispensable

The GX-CO2-30 ensures safety and compliance across a wide range of commercial and technical environments:

• Gastronomy & dispensing systems: Monitors CO₂ cylinders, taps, and beer lines – prevents dangerous concentrations.
• Breweries & filling plants: Secures production, storage, and logistics – early leak detection.
• Cold rooms & dry ice storage: Detects CO₂ leaks from containers – protects personnel and goods.
• Large kitchens & cafeterias: Controls CO₂ in sparkling systems and refrigeration – ensures a safe working environment.
• Food production: Monitors CO₂ atmospheres in packaging and storage – meets hygiene and safety standards.
• Wine cellars & vinotheques: Protects against CO₂ from fermentation or cylinders – ensures quality and safety.
• Research & laboratories: Safeguards CO₂ use in climate chambers and incubators – precise and reliable.

With the GX-CO2-30, you choose a system that not only warns but actively protects – before CO₂ becomes a hazard.

It is the perfect complement to the GX-A1+ and GX-HS and a clear commitment to safety, sustainability, and operational continuity. Its easy integration, robust construction, and German quality make it the first choice for restaurateurs, brewers, logistics operators, and facility managers. Order now and breathe easy – literally. The GX-CO2-30: your silent guardian in noisy workplaces.
