OPERATION MANUAL FOR
MINIATURE ICPPRESSURE SENSOR
105A AND 105C SERIES
1
1.0 INTRODUCTION
This model series is designed to satisfy the need for
measurement of dynamic pressures where space is
limited, such as in model testing.
The series consists of three basic mechanical
configurations or styles, each featuring a .099”
diameter diaphragm and each with a built-in
impedance-converting amplifier for simple,
convenient, two-wire, low-impedance operation.
2.0 DESCRIPTION
The Series 105A sensors utilize two quartz discs in a
thickness compression mode to produce a high-
impedance level signal which is impressed across the
input of a microminiature impedance
converter built into the sensor housing.
The signal is superimposed upon a +11 volt (nominal)
bias level at the amplifier output and is normally
decoupled from the bias voltage in the power unit.
This signal can be fed directly into most common
readout instruments such as oscilloscopes, digital
voltmeters, AC meters, peak meters, recorders, etc.
The output impedance is less than 100 ohms.
Consult guide G-0001B "General Guide to ICP
Instrumentation" for a more complete treatment of the
ICP(Integrated Circuit Piezoelectric) principle.
3.0 INSTALLATION
Because of the miniature size of these units, extra
care should be exercised in preparation of mounting
ports and in installation of sensors into the ports.
Individual dimensional, performance and installation
drawings are included in the manual for each
particular model. Adhere carefully to instructions on
these drawings.
It is not necessary to use low-noise treated coaxial
cable as with high-impedance type sensors. PCB
Model 002A Cable is recommended.
3.1 MODEL 105A
This is the smallest of the three styles and it is
supplied in only the 100 psi range.
The Model 105A is normally mounted using Model
060A04 Clamp Nut (supplied); however, if lack of
space precludes the use of the clamp nut, the sensor
may be epoxied in place if necessary.
Do not over torque clamp nut, as to do so may distort
the body of the sensor and affect the sensitivity of the
device.
The electrical connection to this model is made by
soldering the positive (center conductor) lead from
the power unit to the .040 diameter solder terminal
provided.
(IMPORTANT! See Section 8.0, page 4)
NOTE: Do not overheat this terminal. Use a small
iron with only enough heat to obtain good solder
joint.
The electrical ground return is made to the sensor
body. This connection can be made by attaching
electrically to the structure or by using the metal
ribbon spotwelded to the sensor body.
3.2 MODELS 105C02, C12 & C22
This style utilizes a 10-32 external thread to facilitate
mounting. It is supplied in three full-scale ranges:
100, 1000 and 5000 psi.
Prepare mounting port in accordance with installation
drawing provided in manual. Do not over torque.
Use only enough torque to obtain a seal.
The electrical connection is made via a 5-44 coaxial
connector. Use coaxial 002G10 cable, 5-44 to 10-32
microdot.

3.3 MODELS 105C03, C13, 23, C33,
C43
This style is the largest and is supplied in five models
with full-scale ranges to 100, 1000, 5000, 10,000 and
30,000 psi.
The electrical connection to this style sensor is made
via a 10-32 coaxial connector.
3.4 FLASH TEMPERATURE
PROTECTION
It is good practice to protect the diaphragm against
flash thermal effects, especially when flush-mounted,
to minimize spurious outputs generated by high heat
influx due to blasts, high compression heating, etc.
One or more layers of black vinyl electrical tape on
the diaphragm can be useful for this purpose in many
cases. RTV-type silicone rubber has also proven
effective.
Experimentation is the best method for determination
of effectiveness of protective material for each sensor
application.
3.5 RECESSED INSTALLATION
If ultra-high frequency response is not needed, it is
good practice to use a recessed diaphragm
installation.

.010 Gap
Typical Recessed Installation
Because of its one-piece machined diaphragm
construction, the 105A series is sensitive over its
entire frontal area. Use extreme care when preparing
recessed installation port to ensure that no particles,
burrs or other residue are entrapped in the .010”gap
ahead of the diaphragm. Force on the diaphragm due
to such entrapped particles may change the
calibration of the sensor.
Recessed mounting protects the sensor diaphragm
from the effects of high-flash temperatures and
particle impingement due to blast effects, thereby
prolonging sensor life.
The limitation is that this type of installation lies in
the high-frequency limiting effects of the passage, due
to its length.
The passage behaves like an underdamped second
order system, the resonant frequency being
determined by the passage length. This can have a
limiting effect on pressure pulse rise time while
causing passage ringing in cases where the passage is
too long with respect to pulse rise time. (See chart
below.)
The following relationship determines this resonant
frequency (fr):

fr (Eq. 1)
Where: fr= Resonant frequency of passage (Hz)
V = Velocity of sound in air (ft/sec)
L = Length of column (ft)

Where L = Passage length (in.)

Passage Resonance vs. Passage Length
Actual resonant frequencies measured in practice may
differ slightly from the chart values due to variations
in the velocity of propagation of sound caused by
changes in temperature and pressure of the medium in
the passage.
For best matching of passage to diaphragm, maintain
the .010”clearance ahead of the diaphragm as shown
in Typical Recessed Installation figure.

NOTE: All PCB signal conditioners for ICPsensor
contain current-limiting circuitry to set the input
current in the range of 2 to 20 mA.
Do not connect a power supply to these units without
current limiting. To do so will destroy the built-in IC
amplifier.
All PCB signal conditioners feature fault-monitoring
voltmeters on the front panel. During normal
operation, the meter will indicate about mid-scale
(+11 volts). If one of the connections to the sensor is
open, the meter will read full scale (yellow area).
Should a short occur on the sensor line, the meter will
read 0 volts (red area).
5.0 CALIBRATION
Because of the relatively short discharge time
constant of this series, static calibration means cannot
be used. Fast dynamic means such as step function or
pulse generators must be used instead.
Contact the factory for help in solving specific
calibration problems.
6.0 MAINTENANCE
The small size and sealed construction of these
sensors precludes field maintenance and repair.
Should a problem develop, contact the factory for
assistance.
