Zirconia oxygen sensor ZS-ST-14

electrochemical4-wirerugged

Cubic ZS-ST-14 is a four-wire mini zirconia oxygen sensor that is designed on the basis of HTCC technology and adopts zirconia as its sensing element to detect the amount of oxygen in motorcycle exhaust systems. Cubic ZS-ST-14 measures oxygen concentration by detecting the potential difference generated by the oxygen ion concentration difference between exhaust gas and reference air. Cubic ZS-ST-14 features an ignition time less than 15 seconds, effectively reducing pollutant emissions during the cold-start phase. Additionally, Cubic ZS-ST-14 features a compact design that fits space-limited installation. With a Thermal Shock Protection (TSP) coated zirconia element, Cubic ZS-ST-14 demonstrates enhanced thermal cycling durability and resistance to condensation for continuous operation in 850°C exhaust environments. Cubic ZS-ST-14 is capable of simulating multiple signal outputs and interfaces directly with the ECU, enabling real-time closed-loop air-fuel ratio control. Produced through in-house manufacturing under an automotive-grade quality management system, Cubic ZS-ST-14 is suitable for both OEM motorcycle production and aftermarket applications. - Zirconia electrochemical technology with HTCC process. - Precise measurement of exhaust O₂ concentration and accurate AFR feedback. - Fast cold start within 15 seconds with a highly efficient integrated heater. - TSP coating resistant to violent engine vibration, dust, and moisture. - Planar and compact structure designed for space-constrained applications. - Four-wire design with plug and play operation for easy installation and integration. - Compatible with nearly all EFI motorcycle models on the market; ideal for OEMs, aftermarket modifications, and service applications.
