The information contained in this document supersedes all similar information that
may be found elsewhere in this manual.
Service –Due to the sophisticated
nature of the sensors and associated
instrumentation provided by PCB
Piezotronics, user servicing or repair is
not recommended and, if attempted,
may void the factory warranty. Routine
maintenance, such as the cleaning of
electrical connectors, housings, and
mounting surfaces with solutions and
techniques that will not harm the
physical material of construction, is
acceptable. Caution should be observed
to ensure that liquids are not permitted
to migrate into devices that are not
hermetically sealed. Such devices
should only be wiped with a dampened
cloth and never submerged or have
liquids poured upon them.
Repair –In the event that equipment
becomes damaged or ceases to
operate, arrangements should be made
to return the equipment to PCB
Piezotronics for repair. User servicing or
repair is not recommended and, if
attempted, may void the factory
warranty.
Calibration –Routine calibration of
sensors and associated instrumentation
is recommended as this helps build
confidence in measurement accuracy
and acquired data. Equipment
calibration cycles are typically
established by the users own quality
regimen. When in doubt about a
calibration cycle, a good “rule of thumb”
is to recalibrate on an annual basis. It is
also good practice to recalibrate after
exposure to any severe temperature
extreme, shock, load, or other
environmental influence, or prior to any
critical test.
PCB Piezotronics maintains an ISO-
9001 certified metrology laboratory and
offers calibration services, which are
accredited by A2LA to ISO/IEC 17025,
with full traceability to SI through
N.I.S.T. In addition to the normally
supplied calibration, special testing is
also available, such as: sensitivity at
elevated or cryogenic temperatures,
phase response, extended high or low
frequency response, extended range,
leak testing, hydrostatic pressure
testing, and others. For information on
standard recalibration services or
special testing, contact your local PCB
Piezotronics distributor, sales
representative, or factory customer
service representative.
Returning Equipment –Following
these procedures will ensure that your
returned materials are handled in the
most expedient manner. Before
returning any equipment to PCB
Piezotronics, contact your local
distributor, sales representative, or
factory customer service representative
to obtain a Return Warranty, Service,
Repair, and Return Policies and
Instructions Materials Authorization
(RMA) Number. This RMA number
should be clearly marked on the outside
of all package(s) and on the packing
Service, Repair, and Return
Policies and Instructions

list(s) accompanying the shipment. A
detailed account of the nature of the
problem(s) being experienced with the
equipment should also be included
inside the package(s) containing any
returned materials.
A Purchase Order, included with the
returned materials, will expedite the
turn-around of serviced equipment. It is
recommended to include authorization
on the Purchase Order for PCB to
proceed with any repairs, as long as
they do not exceed 50% of the
replacement cost of the returned
item(s). PCB will provide a price
quotation or replacement
recommendation for any item whose
repair costs would exceed 50% of
replacement cost, or any item that is not
economically feasible to repair. For
routine calibration services, the
Purchase Order should include
authorization to proceed and return at
current pricing, which can be obtained
from a factory customer service
representative.
Contact Information –International
customers should direct all inquiries to
their local distributor or sales office. A
complete list of distributors and offices
can be found at www.pcb.com.
Customers within the United States may
contact their local sales representative
or a factory customer service
representative. A complete list of sales
representatives can be found at

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-0001B, 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
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
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

threaded adaptor with floating clamp nut 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".
Models 102A21 and 102A22 are high-temperature
ICP® versions to 400 F (204 C), with a 3/8-24
straight threads adaptor and 1/8-27 NPT adaptor,
respectively.
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-0001B for 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-0001B 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 484B 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.
