3.  Transducer Installation 

 

General; mount the transducer as close to the action as possible, the sensing face is 

VERY

 sensitive and easily damaged, be very careful with it.  

 
Only mount the transducer in the Vacuum Interceptor when no other option is practical – 
it will still work well but in high vacuum loss situations the vacuum at the cups will be 
lower than at the transducer sensing face due to friction losses in the plant pipe work. 
 

Herringbone Dairy 

– mount in the Hygienic Can as first choice or Milk Receiver as 

second choice. The Hygienic can be drilled and a standard mounting kit used or insert in 
the Milk Receiver, this will require the tri-clover fitting welded in (see photo) and creates 
a point that must be cleaned periodically and therefore provides a risk of damaging the 
transducer.
