Repair and Maintenance
PCB guarantees Total Customer Satisfaction through its
“Lifetime Warranty Plus” on all Platinum Stock Products
sold by PCB and through its limited warranties on all other
PCB Stock, Standard and Special products. Due to the
sophisticated nature of our sensors and associated
instrumentation, field servicing and repair is not
recommended and, if attempted, will void the factory
warranty.
Beyond routine calibration and battery replacements
where applicable, our products require no user
maintenance. Clean electrical connectors, housings, and
mounting surfaces with solutions and techniques that will
not harm the material of construction. Observe caution
when using liquids near devices that are not hermetically
sealed. Such devices should only be wiped with a
dampened cloth—never saturated or submerged.
In the event that equipment becomes damaged or ceases
to operate, our Application Engineers are here to support
your troubleshooting efforts 24 hours a day, 7 days a
week. Call or email with model and serial number as well
as a brief description of the problem.
Calibration
Routine calibration of sensors and associated
instrumentation is necessary to maintain measurement
accuracy. We recommend calibrating on an annual basis,
after exposure to any extreme environmental influence,
or prior to any critical test.
PCB Piezotronics is an ISO-9001 certified company whose
calibration services are accredited by A2LA to ISO/IEC
17025, with full traceability to SI through N.I.S.T. In
addition to our standard calibration services, we also offer
specialized tests, including: sensitivity at elevated or
cryogenic temperatures, phase response, extended high
or low frequency response, extended range, leak testing,
hydrostatic pressure testing, and others. For more
information, contact your local PCB Piezotronics
distributor, sales representative, or factory customer
service representative.
Returning Equipment
If factory repair is required, our representatives will
provide you with a Return Material Authorization (RMA)
number, which we use to reference any information you
have already provided and expedite the repair process.
This number should be clearly marked on the outside of
all returned package(s) and on any packing list(s)
accompanying the shipment.

OPERATION MANUAL FOR
SPARK PLUG ADAPTOR
MODEL 65
Model #65 Spark Plug Adaptor provides convenient mounting of miniature quartz
transducers in spark ignition engines for measuring combustion pressures. Most standard
spark plugs (with exception of a few very long reach or experimental plugs) can be
modified. Drawing 065-1010-90 shows details of the miniature transducer mounted in the
spark plug adaptor.
When ordered together the transducer is mounted in the spark plug, pressure tested and
ready to operate. The clamp which holds the transducer in place is locked with a small
amount of epoxy at the base of the threads. If necessary to install or remove the
transducer hold the hex at the adaptor base with one wrench while turning the clamp with
another. This prevents torque being applied to the small diameter tube connecting the
adaptor body to the spark plug. Mounting torque on the clamp should be around 25 inch
pounds. Excessive torque may cause the seal sleeve to collapse and the transducer
diaphragm to bottom against the adaptor base which will cause a completely erratic trace.
The seal sleeve should maintain a clearance between the transducer diaphragm and base
of about .003”to .007”.
It is advisable to pressure test the adaptor after installing or removing the transducer to
assure it does not leak. Even a very small leakage of high temperature gas causes high
heat transfer rate and may damage the crystal.
When the spark plug transducer is operated on a stationary engine it is necessary to air
cool the adaptor housing the transducer. This is usually accomplished by placing the
Teflon tube over the transducer housing and direct a jet of compressed air thru it. On
operating engines which have the cooling fan to create air flow around the transducer the
Teflon tube may be used around the ignition wire to insulate between the transducer
housing and spark plug. DO NOT USE THE TEFLON TUBE OVER THE
TRANSDUCER HOUSING UNLESS COMPRESSED AIR IS BEING BLOWN THRU
IT.
ICB Transducer systems are not nearly susceptible to ignition interference as the charge
systems. Equipping the engine with high resistance ignition cable will minimize ignition
interference with either system.
MAINTENANCE
After prolonged use carbon deposits may build up at the transducer diaphragm and in
small diameter passage. At the first sign of signal distortion disassemble transducer from
spark plug and clean carbon from adaptor base. Run a piece of piano wire through the gas
passage to clean it. When reinstalling the transducer use a new seal if necessary and make
sure adaptor base is clean so it will seal. The seal has a taper on one end which should
mount against the adaptor base. Use a small dab of epoxy , Loctite , or other binding
compound on the adaptor base threads to prevent vibrations from loosening it.

POINTS TO REMEMBER
Spark Plug Transducer assemblies supplied from the factory are sealed and
pressure tested for leaks. If disassembled be sure to pressure test for leaks before
reuse.
On stationary engines (especially those with cooling fans removed) direct a jet of
cooling air thru the Teflon tube placed around transducer housing. When road
testing engines remove the Teflon tube from around the transducer housing so the
engines cooling fan will provide adequate air cooling.
