Sensing the invisible, protecting the irreplaceable.
Deploying the next iteration of gas safety mechanisms. Xinhaosi invests extensively in semiconductor technology, micro-electromechanical systems (MEMS), and optical gas spectroscopy.
By utilizing micro-machined silicon wafers, our next-gen MEMS gas sensors reduce power consumption by up to 80% while significantly shortening warm-up times. This makes them ideal for integration into smart wearable personal monitors and IoT utility networks.
Non-Dispersive Infrared (NDIR) and Tunable Diode Laser Absorption Spectroscopy (TDLAS) platforms offer selective target gas calibration (such as CH4, CO2, or SF6) without cross-sensitivity or danger of catalyst poisoning in oxygen-depleted atmospheres.
By pairing sensors with custom AI algorithms on intelligent gateways (like the FDG-X304SE), our systems dynamically filter out environmental noise (relative humidity, ambient heat, pressure swings), cutting false alarm rates by 95%.
Protecting assets and processes from toxic, combustible, and suffocating gas hazards. Xinhaosi tailors system architectures to specialized operational zones.
Industrial refineries demand robust explosion-proof ratings (Ex d IIC T6) and structural reliability. Our XP4000 series monitors toxic VOCs and combustibles in extreme temperatures. These are configured directly with automated industrial shut-off valves (XF3 series) for swift mechanical override in crisis situations.
Enclosed parking spaces pose dynamic CO accumulation risks. The AT2004BIV-CO sensor array coordinates with the ventilation controller system, automatically spooling up exhaust fans when carbon monoxide levels rise above preset limits. This preserves power and cuts building carbon footprints.
Gas utility networks require low-maintenance, battery-operated monitoring devices. By using wireless smart pressure monitors and low-power LoRa/NB-IoT data terminals (like the GT-AT0636), utilities can map line pressures and spot trace leaks across vast municipal service areas in real time.
At our advanced production plant, safety is engineered into every component. Our production line operates on digitalized traceability protocols, ensuring every gas sensor is tracked through fabrication, assembly, gas calibration, and environmental stress testing.
We welcome third-party inspections (SGS, TÜV SÜD, Intertek) to audit our Chengdu manufacturing facility. Our processes are ISO 9001, ISO 14001, and ISO 45001 certified.
Xinhaosi Quality Assurance Guarantee
Each sensor is shipped with a unique batch test record, enabling immediate traceability down to the raw silicon component.
Working with global EPCs and safety officers requires strict adherence to international explosion protection and functional safety standards.
Our heavy industrial explosion-proof transmitters are designed to meet Zone 1 and 2 hazard profiles. Their flameproof enclosures (Ex d) and intrinsically safe electronics (Ex ia) prevent electric sparks or thermal discharge from igniting surrounding flammable mixtures.
Designed to meet IEC 61508 standards, Xinhaosi safety controllers carry SIL2 ratings, supporting redundancy configurations that reduce failure probabilities. This satisfies safety integration requirements for critical oil, gas, and power systems.
Through partners and localized service centers, we supply on-site system integration support, field calibration assistance, and commissioning support, helping safety managers keep safety loops operating with minimal downtime.

Get expert answers to common questions about choosing, installing, and maintaining gas detection equipment.
Catalytic bead sensors rely on the oxidation of combustible gases on a heated bead, altering its electrical resistance. They are effective for monitoring LEL levels of explosive hydrocarbons, but they require oxygen to function and can be poisoned by silicones, lead, or sulfur. Electrochemical sensors, by contrast, measure changes in current as targeted toxic gases (like CO, H2S, or NH3) react chemically on an electrode. They operate in oxygen-depleted zones and are sensitive to parts-per-million (ppm) changes.
Sensing cells naturally degrade over time, causing their zero and span values to drift. While most factory specifications suggest a 6-month calibration window, factors like constant background gas exposure, dust accumulation on gas membranes, extreme temperatures, and ambient humidity can require more frequent adjustments. Deploying smart gateways like the FDG-X304SE lets technicians monitor sensor health remotely, helping them plan maintenance cycles more effectively.
Safety Integrity Level (SIL) ratings measures safety reliability. A SIL2-certified gas safety loop (which pairs a controller like the JB-TB-AT2020SEL with an industrial solenoid valve like the XF3 series) ensures a low probability of failure on demand (PFD). If a leak is detected, this rating guarantees the automated safety systems will step in and shut off the gas flow, protecting workers and plant equipment.
Our wireless terminals (such as the GT-AT0636 and pressure monitors like the AT0635) use low-power sub-GHz networks (LoRaWAN, NB-IoT, or Zigbee). These networks bypass physical barriers like walls and piping to send data to centralized controllers. Working on long-lasting internal lithium batteries, these wireless sensors are ideal for remote monitoring where running conduit and wiring is impractical.
