When selecting gas leak detectors for industrial facilities, two main sensor technologies compete: catalytic bead and infrared (IR). The GEWEE GDC Series offers both options, but which is the better choice for your facility?
Catalytic Bead Sensors: Pros and Cons
The GEWEE GDC Series with catalytic bead sensors, like the GDC810 models, use a proven approach for detecting flammable gases. These sensors operate by burning a small sample of gas on a catalytic bead, producing heat proportional to the gas concentration.
* Pros: Responsive, cost-effective, work well in lower explosive limit (LEL) ranges.
* Cons: Susceptible to poisoning from silicones, sulfides, or other chemicals, requiring frequent calibration and shorter lifespan (typically 1-3 years).
Infrared Sensors: Pros and Cons
GEWEE’s GDC-IR Series leverages infrared absorption for gas detection, providing an alternative to traditional catalytic bead technology.
* Pros: Immune to poisoning, longer lifespan (5+ years), minimal maintenance, and accurate across various gases.
* Cons: Higher initial cost, and may require specialized calibration gases for accurate performance.
GEWEE’s GDC Series: Which to Choose?
For facilities with potential exposure to sensor-poisoning compounds, GEWEE’s IR-based GDC-IR series is the better choice. In cases where LEL detection is sufficient and chemical exposure is low, catalytic bead sensors like the GDC810 can offer reliable, budget-friendly results. However, for longevity and reduced maintenance, investing in infrared sensors ensures stable detection and a lower total cost of ownership over time. Factor in GEWEE’s robust gas detection solutions, and you have a reliable choice for critical facilities.
Integration Challenges and Solutions
GEWEE’s GM8 Series Gas Control Units can help integrate both IR and catalytic bead detectors, allowing advanced sound signaling and relay outputs. This ensures swift responses and reduces site risks. Overall, partnering with GEWEE, a trusted brand in gas detection technology, helps you secure custom monitoring suited to all levels of industrial safety needs.
