OPERATION MANUAL FOR
ICP® HIGH PRESSURE SENSORS
Series 108 & 109
1
1.0 INTRODUCTION
The 108 & 109 Series are acceleration-compensated,
high pressure, ICP® (Integrated Circuit Piezoelectric)
sensors primarily developed to measure ballistics
chamber pressures for R & D and production testing
of ammunition. They may also be used for explosive
air blast and other high pressure measurements in
extreme shock environments where ultra-fast, micro-
second response is required. These types of tests are
usually accompanied by large acceleration pulses,
which can add considerable error to output signals of
un-compensated sensors.
The shoulder seal design features a one-piece
diaphragm machined integral with the housing for
ruggedness.
For applications where strain sensitivity from stress
within the mounting port is a concern, the 108A1X,
108B1X, 109B1X and 109C1X utilize a floating
clamp-nut design to reduce the effects, where “X”
denotes pressure range.
2.0 DESCRIPTION
The 108 & 109 Series contain an acceleration-
compensated piezo element, which is coupled to a
microelectronic amplifier. The quartz element
contains an integral seismic mass that counteracts the
acceleration effects of the end piece and diaphragm.
This compensation acts to extend the frequency
characteristics and enhance the transient response of
the sensor.
The machined diaphragm is made from maraging
steel, selected because of its high strength and
durability. The combination of the short, rigid
element and stiff diaphragm give these sensors a high
natural frequency and linearity.
The microelectronic amplifier converts the high-
impedance voltage from the quartz package into a
low-impedance, high-level output signal. See the
Technical Information section of our website for
more complete coverage of ICP® instruments.
3.0 INSTALLATION
With a 3/8-24 (M10x1.0 for metric mount) mounting
thread and flush diaphragm design, the 108 & 109
Series transducers mount directly in existing ports
machined for PCB Series 118 & 119.
Unlike conventional diaphragm type sensors, the 108
& 109 Series are pressure sensitive over the entire
frontal area. Extra care should be exercised to avoid
bottoming in the mounting hole when recess mounted
or when mounting into existing ports.
Install the sensor, using only one of the seals
provided, with the aid of a torque wrench to monitor
the mounting torque value. The recommended torque
range can be found on the installation drawing. Seals
should be replaced each time the sensor is re-
installed.
3.1 MOUNTING IN EXISTING
RECESSED PORTS
Before installing the sensor in previously used
mounting ports, clean out the residue from previous
tests. The port can be cleaned by hand reaming the ¼
inch diameter hole using a PCB Model 040A end
cutting reamer (040A07 for metric mount) guided by
PCB Model 041A pilot bushing (M041A for metric
mount).
Pay particular attention to the sealing surface,
keeping it free from tool chatter marks, nicks and
other imperfections that could adversely affect the
seal. If the sealing surface requires re-machining
after prolonged use, refer to the installation drawing
to ensure that the ¼ inch hole is deepened to avoid
bottoming of the sensor when re-installed.

If waveform distortion occurs during prolonged
testing, remove the sensor and clean the residue as
illustrated above.
3.2 PREPARING NEW MOUNTING
PORTS
Refer to the installation drawing provided in this
manual for instructions on mounting hole
preparation. For best results, do not deviate from the
steps outlined in this drawing.
To assist new mounting port preparation, PCB offers
the 040B20 Tooling Kit (040B21 for metric mount).
These installation kits provide all of the necessary
tooling required to drill, ream, and tap the mounting
ports for proper installation of the 108, 109, 118 and
119 Series transducers.
Use good machining practice in preparation of the
mounting port, paying particular attention to the seal
surface. It is important that this surface be perfectly
smooth and free from tool chatter marks, nicks and
other imperfections which might cause leaks at high
pressures.
3.3 RECESSED MOUNT
The recessed installation is shown in the Recessed
Mount figure. This type of mounting protects the
sensor diaphragm from the effects of high-flash
temperatures and particle impingement due to blast
effects, thereby prolonging sensor life.
The recommended range of passage diameters is
0.090 to 0.125 inch (2.29 to 3.18 mm) diameter.
The limitation in this type of installation lies in the
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. The length may
have a limiting effect on pressure pulse rise time and
cause passage ringing in cases where the passage is
too long.

The following relationship approximates this
resonant frequency (f r):

Where: f r = Resonant frequency of passage (Hz)
V = Velocity of sound in air (ft/sec)
L = Length of column (ft)

Passage Resonance vs. Passage Length
Actual resonant frequencies measured in practice
may differ slightly from the chart values. These
differences are due to variations in the velocity of
propagation of sound in air caused by changes in
temperature and pressure of the air in the passage.
For best matching of passage to diaphragm, maintain
the 0.010 inch (0.254 mm) clearance ahead of the
diaphragm as shown in the Recessed Mount figure on
the previous page.
3.4 FLUSH MOUNT
In the flush mount installation, there is no reduced
area passage from the sensor diaphragm to the test
chamber; rather the sensor diaphragm is mounted
flush with (or slightly recessed from) the inside
surface of the test chamber.
Use this type of installation only if space or rise time
considerations preclude the use of recessed
installation.
In severe pyrotechnic environments, sensor life may
be severely limited with flush installation.
3.5 FLASH TEMPERATURE
EFFECTS
If more protection from flash thermal effects is
required with the recessed mount, the passage can be
filled with silicone grease (DC-4 or equivalent).
Several layers of black vinyl electrical tape directly
on the diaphragm have proven effective in many
cases as well.
Flash temperature effects are usually longer term and
will show up as a baseline shift long after the event to
be measured has passed.
For flush mount installations, a silicone rubber
coating approximately 0.010 inch thick can be
effective; RTV 106 is recommended, and is available
from PCB as Model 065A67. Follow manufacturer’s
instructions to apply. It is best to recess the
diaphragm 0.010 inch for this type of protection.
3.6 INSTALLING CABLES
It is convenient, though not necessary, to use coaxial
cable, such as PCB 002 Series, to connect the
transducer to the power unit. Cable need not be low-
noise treated.
If the use of lighter, more flexible cable is desired,
PCB Model 070B09 solder connector adaptors may
be used to employ twisted pair or other types of two-
wire cable.

3.7 CIRCUIT CONNECTIONS
The figures below show two typical circuit
connections normally used to connect the 108 & 109
Series to power units.
The first figure is the connection scheme used for
most applications. In this set up, the signal is AC-
coupled from the bias voltage meaning the voltage at
the "scope" terminal will be at a zero volt bias level.
Normal Connection AC-Coupled Output
In this case, the system discharge time constant will
be determined by the input resistance and capacitance
of the power unit. Most PCB power units have
approximately a 10 second discharge time constant.
Alternate Connection to take Advantage of Sensor
Discharge TC
The second figure illustrates an optional connection
scheme which can be used during calibration to take
full advantage of the sensor’s discharge time
constant.
With this arrangement, the readout is direct-coupled
to the sensor and the output signal will be added to
the DC bias voltage (11 VDC nominal).
The discharge time constant will then be determined
only by the sensor and should be in the order of 2000
seconds; this is sufficient for most types of static
calibration methods. (See Calibration Section 4.0)
Typical Connection
The figure above shows the 108 & 109 Series
connected to a PCB Model 484B06 power unit. The
484B06 is a power unit that can be AC or DC-
coupled.
In the DC-couple mode, a level-shifting circuit
removes the bias level and provides a zero adjust
feature at the front panel. The system’s discharge
time constant is determined by the sensor in this
mode.
An AC-coupled mode is provided for normal AC-
coupled operation.
4.0 CALIBRATION
PCB 108 & 109 Series sensors are supplied with a
calibration certification from the factory.
Recalibration services are provided at the factory for
a nominal fee.
Static calibration methods may be employed using
the set-up shown in the Alternate Connection figure
or by use of the Model 484B06 Power Unit as shown
in the figure above – use the 484B06 in DC mode.
Following thermal stabilization of the sensor, use a
high pressure pump with dial reference sensor or a
dead weight tester to apply pressure in desired
increments to full scale. Release pressure after taking
the reading and before proceeding to the next higher
pressure level.
With a 2000 second discharge time constant, 1% of
the signal will be lost in 20 seconds, so it is
imperative that the pressure setting and recording of
output be accomplished quickly.
A calibration graph can be plotted using output
voltage vs. input pressure to determine sensitivity and
linearity.

5.0 OPERATION
Select desired mode of circuit connection and turn
power unit on.
Observe fault monitor meter at the front panel of the
power unit.
Normal operation is indicated by an approximate
midscale reading. Shorted cable or connections are
indicated by a zero reading (red area).
Open cable or connections are indicated by a full-
scale (yellow area) reading.
Allow instrument several minutes to warm up and
thermally stabilize.
When output from the power unit is connected to
readout equipment, a drift in the voltage signal will
be noticed; this is normal. This voltage signal drift is
caused by the charging of the coupling capacitor in
the power unit and will cease within several minutes.
6.0 POLARITY
The 108 & 109 Series are designed to produce a
positive output voltage for increasing pressure at the
diaphragm.
7.0 MAINTENANCE
The small size and sealed construction of the 108 &
109 Series precludes field maintenance and repair.
