2760 In-Line models used with 2724-2726 series electrodes:

1.  The 2724-2726 can use a Signet installation 

fi

 tting. Electrodes are sealed by the O-ring when it is installed into a Signet 

installation 

fi

 tting.

2.  The lower threaded nut is required to attach the electrode to the 

installation 

fi

 tting when using a Signet 

fi

 tting.

HAND-TIGHTEN THE THREADED NUT ONTO THE 
INSTALLATION FITTING.

 

DO NOT USE TOOLS!

DO NOT USE THREAD SEALANT OR LUBRICANTS 
ON THE FITTING THREADS OR THE SENSOR CAP

.

3.  Lubricate O-rings with a non-petroleum based, viscous lubricant 

(grease) compatible with the system.

4.  Seat the 2760 DryLoc connector onto the top of the electrode.
 

Open the DryLoc connector by turning the upper locking ring ¼-turn clockwise.

5.  Turn the locking ring ¼-turn counter-clockwise to lock the preampli

fi

 er in place. The mechanism will “click” when it is locked.

 

When fully assembled the 2760 will stand about 100 mm (4 in.) above the installation 

fi

 tting.

2760 In-Line models used with 2764-2767 or 2774-2777 series electrodes:

BEFORE YOU START:
 

2764-2767: Install a 1 in. NPT pipe tee into the process line.

 

2774-2777: Install a ¾-in. reducing tee into the process line.

1.  Wrap the process threads on the electrode with an 

appropriate sealant (example: PTFE tape ) to create a 
water-tight connection. 

HAND-TIGHTEN

 the electrode into 

the installation 

fi

 tting. 

DO NOT USE TOOLS!

 

NOTE:

 The lower threaded nut may be dropped onto the top 

of the electrode or it may be discarded. It is not used with 
these electrodes.

2.  Lubricate O-rings with a non-petroleum based, viscous 

lubricant (grease) compatible with the system.

3.  Seat the 2760 DryLoc connector onto the top of the 

electrode.

 

Open the DryLoc connector by turning the upper locking ring ¼-turn clockwise.

4.  Turn the locking ring ¼-turn counter-clockwise to lock the preampli

fi

 er in place. The mechanism will “click” when it is locked.

 

When the 2760 Preampli

fi

 er is fully assembled with one of the threaded electrodes (276X and 277X models) it will stand 

approximately 178mm (7 in.) from the process threads to the top of the preampli

fi

 er.
