The Bomag 08821423 NOX Sensor is a genuine OEM emissions sensor designed for a wide range of Bomag BW-series tandem rollers, single drum rollers, and pneumatic tyred rollers. Sourced directly from Bomag, this sensor meets the original engineering specification and installs directly in place of the factory unit. Compatible machines include the BW 191 AD-5, BW 206 AD-5, BW 213 D-5, BW 216 DH-5, BW 219 DH-5, BW 226 DH-5, and BW 28 RH, among many others across the BW-series lineup. Replacing a failed or degraded NOX sensor with a genuine part restores proper emissions system function and keeps the engine management system operating correctly.
Key Features
- Genuine OEM Emissions Accuracy — calibrated to the original specification for precise nitrogen oxide detection, ensuring the engine control unit receives accurate exhaust data
- Direct Drop-In Replacement — matches the original connector, thread pitch, and mounting configuration so this sensor installs without modification
- Broad BW-Series Coverage — fits Bomag tandem rollers including the BW 190 AD-5, BW 202 AD-5, and BW 206 AD-5, single drum rollers including the BW 211 D-5, BW 213 D-5, BW 216 D-5, BW 219 D-5, and BW 226-5, and the BW 28 RH pneumatic tyred roller
- Engine Management Protection — a functioning NOX sensor allows the ECU to correctly regulate aftertreatment systems; a failed sensor can trigger fault codes, derate engine power, and cause unnecessary shutdowns on the job
- Emissions System Compliance — replacing this sensor with a genuine Bomag part supports proper Tier 4 / Stage V aftertreatment operation, which is critical for regulatory compliance on regulated worksites
The NOX sensor monitors nitrogen oxide concentration in the exhaust stream and feeds that data to the engine control unit, which uses it to regulate the selective catalytic reduction (SCR) aftertreatment system. When this sensor fails or reads inaccurately, the ECU can no longer correctly dose diesel exhaust fluid (DEF), leading to fault codes, reduced engine output, or a forced machine shutdown. Replacing a worn or faulty sensor with a genuine Bomag part restores full emissions system control and prevents unnecessary downtime caused by aftertreatment faults.
