Sensor Replacement: 

The sensor is an oxygen driven fuel cell. At the end of its typical life of 12 - 15 
months, the output of the cell will fall to zero in less than a day. If the sensor will no 
longer recalibrate, it should be replaced. It is recommended that sensors be replaced 
regularly at 12 month intervals. 
 

Sensor Handling Warnings: 

 

do not expose open end of sensor housing to liquids, particulates, grease etc. 

 

do not touch top of sensor within open end of sensor housing 

 

do not allow vacuum grease to coat open end of sensor 

 

do not expose sensor housing to sudden mechanical or electrical shocks 

 

do not expose sensor to temperature extremes below 0°C or above 45°C 

 

sensors may be stored for up to one year in a refrigerator at 7°C. DO NOT 
FREEZE. 

 

S Sensor Replacement Procedure: 

1.

 

Remove Sensor Cable from the existing sensor. Cable is removed by unscrewing 
the locking nut. 

2.

 

Remove the old Sensor by unscrewing counterclockwise from Sensor base/process 
fitting. Discard Sensor to prevent accidental re-use. 

3.

 

Remove and discard the old O-Ring from sensor housing. 

4.

 

Install pre-greased O-Ring into O-Ring groove on sensor housing. MAKE SURE 
O-RING IS PROPERLY SEATED. 

5.

 

Install the replacement Sensor onto the base/process fitting by threading on 
clockwise. Fully had tighten sensor to ensure O-Ring compression. 

6.

 

Connect cable to Sensor by screwing locking nut. 

7.

 

Perform leak test. (with positive pressure - apply leak solution)
