Import Cirius1 Miniature Infrared Methane Gas Sensor — Buy in wholesale FOB from Supplier in China

The Cirius1 Miniature Infrared Methane Gas Sensor from Week Technology Ltd. is a non-dispersive infrared (NDIR) device designed for detecting methane and hydrocarbon gases at concentrations from 0 to 100% LFL or 0 to 100% volume. It operates using a pulsed infrared source at 2 to 4 Hz, with dual-element detection that separates active and reference wavelengths to isolate gas absorption signals. The sensor outputs a small AC signal superimposed on a DC pedestal, requiring external circuitry for amplification and linearization. Its all-metal housing and sealed optical path ensure durability and immunity to ambient light interference.

The sensor includes an embedded thermistor for internal temperature monitoring, enabling compensation for drift under varying environmental conditions. Typical industry standards for NDIR methane sensors specify a response time under 15 seconds and operating temperature ranges from -20°C to +55°C, which this model meets. The electrical interface follows the industry-standard 7-pin configuration, with isolated housing to prevent ground loops. No consumables or filters are required, and the design eliminates susceptibility to sensor poisoning from silicones or sulfides common in industrial environments.

This sensor is commonly used in industrial safety systems, landfill monitoring, and natural gas leak detection where precise, maintenance-free methane measurement is critical. Buyers include manufacturers of fixed gas detectors, OEMs in process automation, and safety equipment integrators in oil and gas. Packaging is bulk or tray-packed with anti-static protection. Lead time and minimum order quantities must be confirmed directly with Week Technology Ltd. as they are not stated in the listing.
