Honeywell has launched a new gas sensor that employs optical non-dispersive infrared (NDIR) technology to identify flammable gases like methane, propane, and butane in industrial environments. The NDIR Hydrocarbon Gas Sensor is designed to enhance safety for workers and facilities across sectors such as mining, oil and gas, petrochemicals, and plastics manufacturing.
Carmen Becker, president of Honeywell Sensing Solutions, emphasized that “accuracy, precision, and reliability are essential in gas detection for worker safety.” She added that the new sensor demonstrates Honeywell’s expertise and commitment to innovative technology that improves operational safety in industries vital to global infrastructure.
The 4-Series NDIR Hydrocarbon Gas Sensor is designed to integrate into fixed and portable gas detectors carried by workers in the field, deep underground or within a processing facility. It is vital for these detectors to use advanced and accurate sensors that can alert workers to potential exposure to hazardous gases.
Because the NDIR sensor will be exposed to harsh conditions, such as dust in mines, methane leaks or extreme indoor versus outdoor temperature fluctuations, it is designed to be durable and reliable in a wide range of settings. The sensor has an integrated condensation reduction system, allowing it to clear excess moisture and maintain performance in humid environments and confined spaces like refineries.
Unlike traditional pellistor or catalytic bead sensors that can degrade or become “poisoned” in harsh environments, the NDIR sensor has high poisoning resistance, limiting the risk of sensor failure and reducing instances of false positives. With infrared technology, the NDIR sensor is also able to consume less power than traditional flammable gas sensors, extending the operational lifespan and prolonging a portable gas detector’s battery.
