A.1.1 Scope. This procedure is for the installation of a transducer. The ballistic pressure
transducer must be seated properly in the test barrel or sensitivity block with sufficient and
proper torque to ensure accuracy and reliable operation.

A.3 EQUIPMENT
A.3.1 Equipment listed in the appropriate Inspection Equipment List shall be used in
addition to the following:
a. Lint-free industrial paper wipes.
b. Degreaser spray
c. High vacuum grease: Heat Stable Silicone type
A.4 SEALING SURFACE PREPARATION
A.4.1 The following procedure shall be followed for all transducer installations, i.e.
sensitivity block, chamber and port positions of the test barrel.
a. Shallow annular grooves (0.001 or 0.002 inches in depth) in sealing surface are
normal; any burning, combustion particle residue or corrosion shall be removed by touching up
the surface with a flat-end reamer.
b. Clean cavity and transducer thoroughly: use clean, lint-free industrial paper wipes and
degreaser spray.
c. Transducer threads shall be coated with a thin film of high vacuum grease prior to
installation.
d. The signal connector on the transducer and interconnecting line shall be wiped clean
with lint-free industrial wipes.
A.5 TRANSDUCER INSTALLATION
a. The sealing ring Type 1100 shall be placed on the face of the DIAG 6215 transducer
and a very small amount of silicon grease shall be placed in the vee impression of the transducer
to make the ring adhere. The diaphragm protection Type 6567 shall then be placed over the face
of the transducer and snapped evenly over this face. A second Type 110 sealing ring shall
