Smart NOx Sensors: Functions and Benefits

Use technical content to support OE cross-reference, diagnostics awareness, and buyer confidence before the RFQ stage.

A critical diesel emissions component used to support regulatory compliance.

Introducción

A NOx sensor, or nitrogen oxide sensor, is used to detect nitrogen oxide emissions from diesel vehicles and support compliance with emissions regulations. Most engines use two NOx sensors: one upstream and one downstream.

As emissions regulations become stricter, accurate NOx detection has become increasingly important. The NOx sensor downstream of the SCR catalyst is used to monitor catalyst performance. Many NOx sensors can also measure O2 concentration, similar to a wide-range air-fuel sensor.

Solicitud

Este sensor puede medir simultáneamente la concentración de NOx en el escape. Al permitir el control de NOx en aplicaciones diésel y de combustión pobre, el sensor contribuye a una mejor economía de combustible y un aire más limpio.

Características

  • Medición simultánea en tiempo real de NOx y O2 concentración
  • Respuesta rapida
  • El diseño impermeable completamente sellado no requiere aire de referencia externo
  • Alta resistencia al agua
  • Alta resistencia a la toxicidad
  • Activación temprana
