Nitrogen Oxide (NOx) Sensors

Key Features

• [SUPERIOR PERFORMANCE] – Bosch NOx sensors deliver highly accurate measurement of nitrogen oxides in exhaust gases with precision down to ±5 ppm — ensuring optimal SCR performance and reduced emissions
• [OE-TRUSTED] – Bosch is a leading OE supplier of NOx sensors worldwide, with millions installed across passenger cars, commercial vehicles, and off-highway applications — and the same OE-proven quality available in the aftermarket
• [LONG LIFETIME] – With a service life of up to 15,000 hours, Bosch NOx sensors feature robust construction — including stainless steel sensor housings, TSP coating and molded Sensor Control Units to ensure dependable operation in the hars
• [FAST RESPONSE] – Bosch NOx sensors feature advanced electrochemical sensing that reacts in as little as 1,000 ms to load changes — allowing for <60 second light-off times, and precise control during acceleration, deceleration, and cold sta
• [ADVANCED SENSOR PRINCIPLE] – Bosch NOx sensors utilize a ceramic electrochemical double-chamber design to detect NOx, oxygen, and ammonia — delivering continuous, simultaneous, and selective signals for precise SCR control and emission com
• [EFFICIENT DEF USAGE] – With precise NOx measurements, dosing of DEF is better matched to demand — ensuring maximum catalyst efficiency, reduced emissions, and lower operating costs through optimized DEF consumption
