-Replacing the measuring cell  

▸

Switch off the electronics, remove the measuring probe from the protection tube and let 
the probe cool down.

▸

To replace the O

2

 measuring cell,  first remove the inner part of the probe (6) (

see 

“Replacing the O

2

 measuring cell”, page 63

).

▸

Then unscrew filter head (1) and remove test gas distributor (2) by loosening the two 
hexagon socket screws.

▸

Now loosen the 4 hexagon socket screws on measuring cell flange (3b) and remove 
measuring cell (3) from measuring probe tube (4). Also carefully remove the old 
measuring cell flange seal (3a).

▸

Clean the flange on the measuring probe tube with fine sandpaper. 

▸

When assembling, the volume reducer must be installed so that the product is Ex-
compliant.

▸

Screw the new measuring cell to the measuring cell flange of the probe tube with a new 
gasket and 4 new screws. 

Note:

It is only necessary to replace the measuring cell if it leaks (jumping or incorrect 
measured values) and a two-point adjustment was faulty.

WARNING:  Risk of burns

The temperature of the probe filter head and all parts in the process gas is 150 °C to 
800 °C (302 °F to 1472 °F) during operation. Directly touching the parts for 
disassembly or maintenance causes serious burns! 

▸

Use heat protection gloves when removing the probe. 

▸

Switch the electronics supply voltage off before removing the probe.

▸

Place the probe in a safe, protected area after removal and wait until the probe 
temperature has cooled down to the ambient temperature.
