Series 103A 1
1.0 DESCRIPTION
The Series 103A microphones are high-sensitivity
pressure sensors featuring miniature size, built-in
solid state electronics and acceleration compensation.
The Model 103A (see installation drawing) has
pigtail leads extending radially from the side of the
unit and has a nominal sensitivity of 1500 mV/psi.
The Model 103A11 is similar in appearance and in
mode of electrical connection, but differs from the
Model 103A in that the sensitivity is nominally 500
mV/psi.
Models 103A and 103A11: ICP® Sound Pressure
Sensors
The Model 103A02 is similar physically to the 103A
and has similar sensitivity (1500 mV/psi), but the
electrical connection is made through a top mounted
10-32 coaxial connector.
The Model 103A12 also has the top connector like
the 103A02 but the sensitivity is 500 mV/psi.
These units are ideal for wind tunnel testing of
models because of the small size and high sensitivity.
Models 103A02 and 103A12: ICP®Sound
Pressure Sensors
2.0 DESCRIPTION
(Refer to installation drawing no. 103-1010-90
included as part of this manual.)
The 103A Series Sensors utilize a bimorph bender
crystal cantilevered from the side wall and attached to
the center of a thin recessed invar diaphragm.
Pressure acting on the surface of the diaphragm
results in a net force which strains (or deflects) the
diaphragm in proportion to the applied pressure. The
diaphragm bends the crystal creating an output
voltage which is also proportional to applied
pressure.
This voltage is fed to the gate of a miniature
MOSFET source follower amplifier which reduces
the output impedance to less than 100 Ohms allowing
the driving of long cables and permitting operating
directly into most readout instruments.
Refer to Bulletin G-0001B, “General Guide to ICP®
Instrumentation”for a detailed description of the
built-in amplifier concept.
Models 103A, A02, A11, and A12 have output
signals superimposed upon a +4 V (approx.) bias
level at the amplifier output. All PCB signal
conditioners are designed to eliminate this bias
voltage while supplying power to the internal
amplifier.

Series 103A 2
The result is a two-wire system, precluding the need
for multi-conductor cabling.
A second diaphragm, located behind the pressure
diaphragm and attached to another bimorph bender
crystal acting in opposition to the pressure crystal,
provides acceleration compensation to the Series
103A Sensors.
3.0 INSTALLATION
As shown in installation drawing 103-1010-90, the
Series 103A Microphones may be properly mounted
in several ways, the exact method chosen being a
function of the space available along with other use
dictated parameters.
The simplest method of mounting, and also the one
that utilizes the least volume, is the adhesive method.
The microphone is simply bonded directly to the
mounting surface with an (at least) .10”diameter hole
through the surface to feed the pressure signal to the
diaphragm.
Many different types of adhesives may be used to
bond the 103A in this manner. The important point
being to apply the adhesive very sparingly so that
removal does not damage the sensor.
The 103A may also be mounted using the Model
061A04 Servo clamps if space is available.
The Model 060A11 Clamp Nut may only be used
with the top connector Models 103A02 and 103A12
since the radial wire leads of the Model 103A and
103A11 would interfere with the clamp nut. The
installation drawing gives detailed instructions on
preparation of the port for this type of installation.
3.1 ELECTRICAL
For the Models 103A and 103A11 (pigtail models),
connect the center conductor from the “Xducer”
output of any ICP®power unit to the white (Pwr/Sig)
lead and connect the outer shell of the “Xducer”
connector to the black (ground) lead. The black lead
is electrically connected to the outer case. (See figure
below.)
Models 103A & All: Electrical Connection
NOTE: No electrical connection is made to the
blue (vent) lead. This lead serves to vent internal
pressure within the sensor when the 103A and
103A11 are used in evacuated chambers. The
internal pressure bleeds out slowly around the wires
of this lead. This lead may be cut off flush with body
if the sensor will never be used in this manner.
To make the electrical connection to the Models
103A02 and 103A12 (top connector models), simply
connect the “Xducer”output of the power unit to the
10-32 coaxial connector using a PCB Model 002C
Series coaxial cable.
The output signal is taken from the power unit
connector labeled “Scope”or “Output”. (See figure
below.)

OPERATION MANUAL FOR
MICROPHONE
Series 103A 3
Refer to Guide G-0001B for tips on power and signal
utilization.
NOTE: The internal low-noise amplifier in the
Model 103A, A02, A11 and A12 differ from the
standard ICP®amplifiers described in Guide G-
0001B in that the turn-on (or bias) voltage is
nominally +4 volts.
Proper turn-on for Models 103A02, A11 and Al 2
will not give center scale reading on the fault monitor
meters found on most PCB signal conditioners but
will show a reading of approximately 20% of F.S. on
these meters. This puts it at the lower limit of the
green (or normal) area of the meters. This is normal
and in no way indicates faulty operation.
4.0 OUTPUT SIGNAL
The output signal from the 103A Series is a voltage
proportional to input pressure. The polarity is
positive-going for increasing input pressure.
The signal is of high enough level and low enough
output impedance to be fed directly into most
oscilloscopes, tape recorders, strip chart recorders, A
to D converters, etc.
Consult the factory for information regarding galvo
driving since special amplifiers are needed to drive
most high-current galvanometers.
Low-frequency response is limited by sensor
discharge TC (given in the specification sheet) and by
coupling time constants throughout the system. To
take full advantage of the TC of the sensor, make sure
that coupling TC's from power unit to readout are at
least an order of magnitude longer than the discharge
TC or use a direct-coupled signal conditioner such as
the Model 484B. Consult factory for details.
5.0 CALIBRATION
The 103A Series Sensors must be dynamically
calibrated using a known step function or pulse, or
with a microphone calibrator.
At PCB, the units are subjected to various calibrated
steps of pneumatic pressure to obtain a linearity curve
over the full range of the instruments.
6.0 MAINTENANCE AND REPAIR
The small size and sealed construction of the Series
103A precludes field maintenance and repair.
Should the time constant degrade or an abnormality
appear in the normal bias voltage, bake the unit out in
a +250° F oven for 1 to 2 hours, then re-test.
If this is not effective or if other problems should
occur, contact the factory for assistance in tracing the
problem or for instructions on returning the unit for
repair.
7.0 PRECAUTIONS
l.) Do not apply voltage to the unit without a
current-limiting device in the line such as
incorporated in all PCB signal conditioners, (20 mA
maximum) to do so will destroy the internal amplifier.
2.) Do not subject these units to temperatures
higher than 250° F.
3.) Do not attempt to disassemble these units as
to do so voids the warranty.
4.) Use caution when removing units that have
been mounted with epoxies or other strong adhesives.
Excessive squeezing or torquing may damage the
units and/or cause a calibration shift.
5.) In vibratory environments, secure cables and
leads to surrounding structures to avoid lead or cable
damage.
6.) Do not over torque when using the Servo
clamps or the clamp nut since this could damage the
units.
7.) Do not overpressure (see specs for
maximum pressure), to do so may change the
calibration.
