Drilling kit
A drilling kit with formed tools for drilling, reaming and tapping is available to facilitate correct preparation of the assembly seat.
The assembly seat must be perfect to assure proper transducer function and long lifetime. Drilling kits are available in the following
versions: KF12, KF18.
Drilling procedure
1) To drill hole (D4) up to a distance from the hole equal to the sum of (A+B+C) (tool 3).
2) Make the pass through hole (D2) by the tool 1.
3) To create the seal seat at a distance from the hole equal to dimension (A) (tool 4).
4) With a roughing tap, create threading 1/2-20UNF-2B (recognizable from the greater number of threads
mouth) (tool 5).
5) With a finishing tap, go over threading 1/2-20UNF-2B up to a distance from the bottom equal to the sum
6) To ream the hole (D2) with reamer (tool 2).
Installation seat check
The dimensions of the assembly seat have to be checked after preparation and before the transducer installation.
Use dummy plug SC 12/18 as follows:
1) Coat the end of the rod with the appropriate ink.
2) Lubricate the threaded part to prevent friction.
3) Insert the dummy plug and screw it fully down.
4) Remove the rod and examine it.
With the exception of 45° surfaces, the ink should be intact on the entire surface.
