NDIR Gas Sensors for Underground Mining Safety
Methane & CO₂ Detection with Non-Dispersive Infrared Gas Technology
Protect lives with accurate methane (CH₄) and carbon dioxide (CO₂) monitoring in underground mines.
Dynament designs advanced NDIR gas sensors for industrial safety, delivering reliable non-dispersive infrared gas detection for methane, CO₂, and other hydrocarbon hazards in harsh mining environments. Our sensors provide stable, low-maintenance performance for fixed and portable underground mine gas detection systems.
The Challenge of Gas Safety in Mining
Why Underground Mines Need Reliable Gas Detection
Methane (CH₄) and carbon dioxide (CO₂) pose serious hazards in confined mining environments:
- Methane: Highly flammable, risk of explosive concentrations
- CO2 is toxic and displaces oxygen, creating asphyxiation hazards
Traditional detection methods often fail under harsh conditions, risking worker safety and compliance.
Why Choose NDIR Sensors for Mining
Non-Dispersive Infrared Gas Detection Delivers Accuracy, Reliability, and Safety
Dynament’s NDIR Methane and CO₂ sensors use optical measurement rather than chemical reactions, making them ideal for continuous underground mine gas detection.
Our NDIR gas sensors for industrial safety provide:
- High accuracy with minimal drift
- Low maintenance with no consumable elements
- Resistance to poisoning and contaminants
- With appropriate protection provide reliable operation in dust, humidity, and temperature swings
- Fast response for early methane leak detection
