Generally, cleaning the electrical contacts or replacing filter elements is the extent of the maintenance requirements of this
transmitter.
Sensor Replacement
Periodically, the oxygen sensor will require replacement. The operating life is determined by a number of factors that are
influenced by the user and therefore difficult to predict.
The normal operating conditions and expected life of the standard sensor are defined in section 4 Specifications.
Serviceability: Except for replacing the oxygen sensor, there are no parts inside the transmitter for the operator to service. Only
trained personnel with the authorization of their supervisor should conduct maintenance.
Caution: DO NOT open the oxygen sensor. The sensor contains a corrosive liquid electrolyte that could be harmful if touched
or ingested, refer to the Material Safety Data Sheet contained in the Owner’s Manual. Avoid contact with any liquid or crystal
type powder in or around the sensor or sensor housing, as either could be a form of electrolyte. Leaking sensors should be
disposed of in accordance with local regulations.
