Measurement Principle & Electrical Performance

Adopts sealed galvanic fuel cell sensing principle, the internal chemical reaction generates current linearly proportional to oxygen partial pressure inside gas samples. This model targets ppm trace oxygen detection with selectable measuring ranges including 0–10 ppm, 0–20 ppm, 0–10000 ppm. Built-in inherent temperature correction characteristic reduces temperature drift during operation. Linear accuracy reaches ±2%FS, repeatability ≤±1%FS, with stable signal output under long-term continuous sampling. Original calibration data matches oxy.IQ host algorithm without extra correction after replacementManualsLib. Operating temperature ranges from 0 ℃ to 45 ℃, applicable sample pressure below 10 psig normal working pressure.

Structural Design & Environmental Adaptability

Wetted structural components resist acidic gas corrosion such as CO₂, solving the corrosion failure problem of ordinary OX-1 sensors in acid media. The flow cell matches standard 1/8 inch NPT sampling pipeline interfaces, paired with sampling filters and pressure stabilizing assemblies to block liquid mist and particulate impurities. Sealed cell structure prevents electrolyte leakage, adapts to chemical process pipelines, natural gas purification systems and inert gas preparation sampling cabinets, and has good vibration resistance for industrial field operation. Wetted parts adopt stainless steel and corrosion-resistant sealing materials to meet industrial medium compatibility requirements.

Matched Equipment & Application Scenarios

Exclusive supporting sensor for GE oxy.IQ two-wire oxygen transmitters. Widely used for trace oxygen monitoring in CO₂ raw gas, chemical process acid gas, inert protective gas, heat treatment annealing atmosphere and semiconductor high-purity gas pipelines. It serves as core consumable spare part when the original oxygen cell is depleted, poisoned or drifts severely.

Stability & Maintenance Advantages

Each sensor undergoes factory gas calibration and aging screening to guarantee consistent measuring performance across batches. No movable mechanical parts inside the fuel cell lower daily maintenance workload; simple plug-in installation shortens field replacement downtime. Original GE OX-2PPM cells avoid measuring deviation and host circuit abnormal current caused by generic substitute sensors. Shockproof sealed packaging meets long-term spare parts storage requirements, and sensing performance remains stable under dry constant-temperature storage conditions.
