Inserting/Removing the insertion sensor

   WARNING – PRESSURIZED EQUIPMENT   

 

When inserting or removing the insertion sensor, the 
safety mechanism (see page 16) must be 

fitted 

and engaged 

to prevent the insertion sensor being 

forced out under pressure. Ensure the valve is fully 
open.

Suitable valve pre-

fitted to process

Valve open/ 

close handle

25 mm (1 in)  

Minimum clearance
