The Net Safety SC310 Catalytic Bead Combustible Gas Sensor is designed for reliable fixed combustible gas detection in demanding industrial environments. Built for use with the Millennium II Series transmitters, including the M21, M22, and M2B, the SC310 provides fast and dependable 0–100% LEL detection for a wide range of flammable gases. Its non-selective catalytic bead sensing technology allows it to detect both hydrocarbon and non-hydrocarbon combustible gases, including methane, propane, butane, ethylene, propylene, and hydrogen.
Engineered for harsh process environments, the SC310 combines rugged housing options, strong resistance to shock and vibration, and stable performance with minimal zero drift related to pressure, humidity, and temperature changes. The sensor’s built-in SensorGuard protection system helps reduce premature sensor burnout during exposure to high gas concentrations, supporting longer sensor life and dependable field performance.
Westech Industrial supplies and supports the Net Safety SC310 in British Columbia, Alberta, and Saskatchewan, helping industrial facilities select, configure, install, and maintain fixed gas detection solutions for their specific applications. For projects requiring more than a standalone sensor, Westech can also support custom fabrication needs, including gas detection panels, mounting arrangements, enclosures, and integrated safety system packages designed for site-specific requirements.

Description
Reliable 0–100% LEL Combustible Gas Detection
The SC310 is built for fixed combustible gas monitoring where early and dependable detection of flammable gas hazards is critical. Its catalytic bead sensing technology provides %LEL measurement across a 0–100% LEL range, making it suitable for industrial facilities that need continuous monitoring for combustible gas leaks.
Detects Hydrocarbon and Non-Hydrocarbon Combustible Gases
Unlike gas-specific detectors that are limited to a narrower target gas, the SC310 offers a non-selective response to a broad range of combustible gases. It can detect common industrial gases such as methane, propane, n-butane, isobutylene, hydrogen, ethane, pentane, hexane, heptane, ethylene, and propylene.
SensorGuard Protection for Longer Sensor Life
The SC310 includes SensorGuard technology, which helps protect the sensor from oversaturation when gas concentrations exceed 100% LEL. This microprocessor-based protection helps reduce premature sensor burnout when concentrated gas remains in the monitored area, supporting longer service life and more reliable operation.
Designed for Harsh Industrial Environments
The SC310 is available with aluminum or stainless steel housing options and is designed for rugged field performance. Its construction supports operation in demanding environments where vibration, shock, weather exposure, and hazardous area requirements must be considered.
Compatible with Millennium II Transmitters
The SC310 is designed for use with the Net Safety Millennium II Series transmitters, including the M21, M22, and M2B. Facilities can configure single or dual channel detection using toxic and/or combustible gas sensors on a Millennium II transmitter, helping reduce the need for separate gas-specific detector installations.
Long-Range Sensor Separation
The SC310 supports sensor separation of up to 2,000 feet / 600 metres using 18 AWG cabling. This provides added flexibility for installations where the sensor must be positioned at the detection point while the transmitter or controller is installed in a more accessible or practical location.
Strong Performance and Fast Response
The SC310 is designed with quick response times, repeatable readings, and stable accuracy for combustible gas detection. With a T90 response time of 12 seconds or less, the sensor supports timely detection in safety-critical applications where fast awareness of gas hazards matters.
Accessories for Field Installation
Available accessories include termination boxes, calibration cup/rain shield/splash guard/dust filter options, inline calibration adaptors, and IP66/67 filters for enhanced protection from dirt and moisture. The instruction guide also outlines compatible sunshade and universal mounting kit options for Millennium transmitter and junction box enclosures exposed to direct sunlight.
Applications
The Net Safety SC310 Catalytic Bead Combustible Gas Sensor is well suited for industrial applications where flammable gas leaks may create safety, environmental, or operational risks.
Common applications include oil and gas production facilities, natural gas processing sites, refineries, petrochemical plants, compressor stations, chemical processing facilities, tank farms, power generation sites, hydrogen-related applications, wastewater and biogas facilities, industrial manufacturing plants, and hazardous area monitoring where fixed combustible gas detection is required.
For facilities upgrading or expanding their fixed gas detection systems, the SC310 can be used as part of a broader plant safety strategy alongside transmitters, alarm devices, control panels, custom mounting, and integrated gas detection system packages.
