Gas detector WG-41.Fx WG-41.FX

Gas Detectors – Reliable Safety in Any Environment

Gas detectors of the WG/Fx series are advanced devices that integrate the functionality of four separate components: a detector with a replaceable sensor module and three alarm thresholds, a control module with relay and voltage outputs, an audio-visual alarm indicator, and a power supply. This comprehensive solution enables precise detection of hazardous gas concentrations, flammable liquid vapors, toxic substances, and oxygen level monitoring in air. These devices are suitable for use in technical rooms as well as industrial environments.

Versatility and Modularity are key features of the WG/Fx detectors. Replaceable sensor modules allow easy adaptation to diverse requirements and ensure cost-effective operation. The wide range of detectable media—from flammable gases to toxic gases and oxygen—makes these detectors ideal for a broad spectrum of applications. The WG-41.Fx model is specifically designed for ammonia (NH3) detection in the range of 500/1500/2000 ppm.

Design and Functionality for Professionals

The WG/Fx detectors have been engineered with ergonomics and reliability in mind. The new sensor housing ensures rapid response to gas presence while maintaining splash protection (IP44 rating). Advanced interfaces—including three relay outputs and two alarm outputs A1 and A2 (12 V / 100 mA)—enable seamless integration with control and alarm systems. Built-in event history and thermal compensation ensure measurement accuracy and simplify data analysis.

Additionally, the devices feature a built-in self-test procedure upon power-up and support external testing without opening the enclosure. An optional mechanical protection cover AR-1d increases resistance to mechanical damage, making them especially suitable for demanding industrial conditions such as warehouses or storage facilities.

Broad Range of Applications

Thanks to their universal design, WG/Fx gas detectors are suitable for numerous applications:

• Enclosed garages and underground parking lots: Control of exhaust ventilation to maintain safe levels of exhaust fumes.
• Solid fuel boiler rooms: Monitoring for carbon monoxide (CO) or other hazardous gases generated during combustion.
• Machinery rooms with refrigerants and cold storage rooms: Detection of refrigerant leaks or oxygen deficiency.
• Technical rooms with air conditioning equipment: Monitoring air quality and safe operation of devices.
• Areas at risk of oxygen excess: Oxygen therapy rooms, HFNO units—monitoring oxygen levels to ensure patient safety.
• Chemical and petrochemical industries: Protection against explosions or poisoning by toxic gases.

Gas detectors WG/Fx represent an investment in safety and user comfort—for both installers and end users. Their reliability, versatility, and ease of operation make them the ideal solution for a wide range of industrial and commercial applications.
