Special Safety Instructions on NOₓ Sensor P/N 56.03.003

 

Explosion hazard!

Only use the NOX sensor for measurement in non-explosive gas mixtures, as explosive gas mixtures can ignite at the hot sensing element. Especially in the event of an engine malfunction, make sure that no unburned gas mixture enters the exhaust pipe. Also comply with all locally applicable explosion protection regulations.

   

Operational safety!

Proper functioning of the NOX sensor is only guaranteed if the sensing element does not overheat at the mounting location. Avoid accumulated heat at the sensing element and ensure sufficient ventilation of the sensing element by ambient air.

   

Operational safety!

To ensure proper functioning of the NOX sensor throughout its service life, be sure to observe the following:

  • The probe must not come into contact with condensation water, other liquid components such as oil and grease, or sealants.
  • Contamination in the exhaust gas, e.g. due to corrosion or material escaping from the catalytic converter, must be avoided.
  • The sensor and its electronics must not be painted or otherwise coated.
  • Do not open the cover of the evaluation unit's connector.

   

Operational safety!

The NOX sensor must not be used any further under any circumstances if it is damaged or the sensing element of the NOX sensor has been mechanically shocked (e.g. by dropping it on the floor or impacts on the sensing element). In these cases, contact MOTORTECH for sensor replacement (see Customer Service Information).

   

Operational safety!

The sensing element may be mounted a maximum of one time. The electrical connection to the NOX sensor's evaluation unit may be established and disconnected a maximum of 20 times. After that, proper functioning of the sensor can no longer be guaranteed.
