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.

1.0 INTRODUCTION
This series of miniature dynamic pressure sensors is
specifically designed for shock tube and blast wave
measurements and for other applications requiring
very high frequency, near non-resonant response.
The term used to describe the transient response of
this model series is “Frequency Tailoring” and it
encompasses several mechanical and electrical design
features coupled with stringent in-process
fabrication/test procedures with heavy emphasis on
the shock tube as a tool.
2.0 DESCRIPTION
Although this series consists of sensors with three
basic mechanical configurations and six different
sensitivities, each model is basically similar in
internal design.
Typical ICP®Probe Style Sensor
Each utilizes the acceleration-compensated Series
113 quartz piezoelectric element coupled to a source
follower type miniature electronics. (See “General
Guide to ICP®Instrumentation,” G-0001, for a
detailed description of the ICP®concept.)
The figure above shows the components of the basic
ICP®probe, i.e. the piezoelectric element and the
ICP®source follower amplifier. These components
are joined together as an inseparable sealed assembly
at the factory. Disassembly should not be attempted
in the field.
Series 113B2x are in a probe configuration and are
installed with a hollow clamp nut with 5/16-24 or
M7x0.75 external threads. The housing of these
models is at electrical ground potential.
Series 113B3x are similar to the B2x Series with an
additional feature; all Invar construction. The all
Invar sensors are designed to have minimal
susceptibility to thermal transient events and are
specifically suited for high-temperature shock and
blast measurements.
Series 113: Probe Style Sensor
Series 102 consist of the basic 113 Series probe, as in
the above mentioned series, mounted in a 3/8-24 or
M10 x 1.0 threaded mounting adaptor. The probe is
installed at the factory in an "off ground"
configuration, i.e. the probe body is insulated from
the external mounting adaptor body.
The Model 102A12 utilizes the same inner probe
design as the above two designs but in a 3/8-24 or

M10x 1.0 threaded adaptor with floating seal to allow
adjustment of diaphragm mounting depth where it is
necessary to adapt to various wall thicknesses. These
models are supplied only as low-pressure (250 psi
and 100 psi) sensors and are also "off ground".
Series 102: Thread Mount Design, Ground-
Isolated Sensor
3.0 INSTALLATION
This manual contains outline and installation
information for your specific model.
Prepare mounting ports in accordance with
instructions given in specific installation drawings,
paying particular attention to sealing surfaces. These
surfaces must be smooth and free from chatter marks,
nicks and other irregularities which could preclude a
pressure tight seal.
To fully realize the high-frequency response
capabilities of this sensor series, flush mounting of
the diaphragm must be used.
In some cases, where flash temperatures such as those
generated by blasts and shock fronts are present, it
may be necessary to thermally insulate the diaphragm
to minimize signals generated by these effects.
Common black vinyl electrical tape has been found to
be an effective insulating material in many cases.
One or more layers may be used across the end of
diaphragm and adaptor.
A silicone rubber coating approximately .010” thick
has also been proven effective in many applications.
General Electric RTV type 106 is recommended.
Apply the rubber coating to the surface of the
diaphragm and allow it to cure in accordance with the
manufacturer’s instructions. (If you have ordered the
CA option, ablative coated models, further protection
will not be necessary.)
Although ICP®sensors have low-output impedance
and in general are not affected by moisture, in
extreme environments it is good practice to protect
cable connections with shrink tubing.
It is not necessary to use low-noise cable with this
sensor series. In fact, an optional Model 070B09
Solder Connector Adaptor allows the use of ordinary
two-wire cable if desired.
4.0 OPERATION
It is only necessary to supply the sensor with a 2 to 20
mA constant current at +20 to +30 VDC through a
current-regulating diode or equivalent circuit. (See
guide G-0001for powering and signal utilization
information pertaining to all ICP®instrumentation).
Most of the signal conditioners manufactured by PCB
have an adjustable current feature allowing a choice
of input currents from 2 to 20 mA. In general, for
lowest noise (best resolution), choose the lower
current ranges. For driving long cables (to several
thousand feet), use higher current, up to 20 mA
maximum.
To operate system using a PCB signal conditioner:
1. Switch power on.
2. Wait several minutes for the IC ampli-
fier to turn on and stabilize.
3. Proceed with measurements.
5.0 POLARITY
The sensors in this series produce a positive-going
output voltage for increasing pressure input.

6.0 LOW-FREQUENCY RESPONSE
The low-frequency response of an ICP®system is
determined by:
1. The discharge T.C. of the sensor
2. If AC-coupled at power unit, the coupling time
constant.
Consult Section 7.0 in guide G-0001 detailed
explanation of low-frequency characteristics of ICP®
instruments.
7.0 HIGH-FREQUENCY RESPONSE
Frequency tailoring and the very high-natural
frequency of the sensor give an extremely wide
usable frequency range (beyond 100 kHz).
Exceptionally fast response time (1 µsec) and clean,
virtually non-resonant response to rapid step
functions are also features of these sensors. As
mentioned previously, the diaphragm must be flush-
mounted to fully realize the high-frequency response
capabilities of this series.
8.0 CALIBRATION
Piezoelectric sensors are dynamic devices, but static
calibration means can be employed if discharge time
constants are sufficiently long. Generally, static
methods are not employed below several hundred
seconds time constant.
To employ static means, direct couple the sensor to
the DVM readout using a T-Connector from the
sensor jack or use the Model 484B06 or 482C24 in
the calibrate mode. Apply pressure with dead weight
tester and take readings quickly. Release pressure
after each calibration point.
For the shorter time constant, rapid step functions of
pressure are generated by a pneumatic pressure pulse
calibrator or dead weight tester and readout is by
recorder or storage oscilloscope.
PCB offers a complete calibration service. Consult
factory for details.
