NOx Sensor Module
NOxGuard/NOxTempGuard System Component
Item no.: 2050050
Only NOx sensors of the approved types (ENSERV Part No. 2050050 / MAN No. 51.15408-0017 or 51.15408-0029) may be connected to the NOxGuard/NOxTempGuard controllers. When replacing the sensors, their serial numbers and the MAN part numbers must be entered into the NOxGuard. Both values are compared with the sensor’s electronic passport, and only then is the new NOx sensor approved.The NOx sensor is installed downstream of the turbocharger as shown in the drawing. If the engine is equipped with a catalytic converter, it is advisable to install the sensor behind it, as some catalytic converters (depending on the coating) already have an effect on NOx reduction.Maximum permissible deviation from the vertical: 80°. The NOx sensor must be mounted in such a way that no condensation can accumulate inside the protective tube of the sensor element.A corresponding weld-on sleeve (90° version) is available from ENSERV. This sleeve is made of a special material (SUS304) to prevent mechanical stress on the probe and to ensure that the NOx probe’s readings are not distorted.

Description
Since both the NOx probe and the weld-on sleeve are made of stainless steel, it is essential to use ceramic mounting paste when installing the NOx sensors. Otherwise, the high temperatures involved can cause the two components to “weld” together, making them virtually impossible to separate.NO calibration is required when replacing the sensors. The sensors are factory-calibrated and come with calibration data. The NOxGuard automatically recognizes this data. Sensors with excessive operating hours (exceeding the end-of-life threshold) can no longer be activated.
