High Precision NDIR Methane Gas Sensor for Industrial Leak Detection

For industrial safety and process monitoring, a HIGH PRECISION NDIR METHANE GAS SENSOR for industrial leak detection is a cost-effective choice. Sangbay Sensor’s 4NCH4 infrared methane sensor stands out with practical performance and industrial adaptability, tailored to diverse on-site demands.

Based on non-dispersive infrared technology, this type of high precision NDIR methane gas sensor covers a 0~100%Vol detection range, with T90 response 0s and 1-minute preheating time—enabling real-time alerts for even little methane leaks. Built-in temperature compensation ensures linear, accurate output even in temperature-fluctuating environments. What is more, anti-water vapor and anti-poisoning design extends service life over 5 years, saving production costs and reducing maintenance times for long-term industrial operations.

Equipped with 3.6~5.5VDC wide voltage supply and mA low power consumption, our high precision NDIR methane gas sensor supports UART and 0.4~2V analog output for seamless integration into PLC systems, gas detectors and IoT monitoring platforms, etc.. Compact (Φ20mm×21.4mm) and IP54-rated, it operates stably in harsh conditions: from -20~60℃ industrial workshops and coal mine ventilation ducts to high-humidity biogas plants and HVAC air quality control systems in commercial buildings.

Ideal for industrial pipeline leak monitoring (oil & gas, chemical), agricultural biogas fermentation process control, and warehouse flammable gas safety pre-warning, the high precision NDIR methane gas sensor replaces traditional catalytic sensors with more reliable performance. Sangbay 4N-CH4 sensor delivers cost-efficient, stable gas detection solutions for global industrial partners across manufacturing, energy, and agriculture sectors.
