Sentronic Oil Pressure Safety Control 

(4D & 6D compressors before March 2011).   

All Sentronics utilize a pressure sensor and an electronic control module to precisely measure oil 
pump differential pressure.  The main advantage of Sentronic is the elimination of the traditional 
capillary tubes, bellows, and pressure connections that mechanical pressure switches require to 
measure differential oil pressure.  These require careful handling and are known to be a source of 
leaks in refrigeration systems.   

 

A second advantage of Sentronic is in the use of a precise electronic clock for the two minute time 
out circuit.  Traditional mechanical controls use resistance heaters to provide the time to trip in the 
event of low oil pressure.  208 volt systems, low ambient temperatures or brown-out type conditions 
cause the heater output to be reduced, thus increasing the time out period from two minutes to three 
or four minutes when low oil pressure conditions exist.  With the electronic clock, the time  out will 
always be the same.   

 

As  a  result  of  the  elimination  of  the  capillary  tube  measuring  system  and  a  more  precise  timing 
circuit, Sentronic will improve the overall reliability of the refrigeration system.  As in the past, all 
new  and  replacement  Copelametic  compressors  equipped  with  oil  pumps  require  the  use  of  a 
Copeland approved oil pressure safety switch.  Failure to use an approved oil pressure safety switch 
will  be  considered  as  misuse  of  the  compressor,  and  can  adversely  affect  warranty  replacement  of 
the compressor should a lubrication connected failure occur.
