OPERATION MANUAL FOR
CONFORMAL BALLISTICS PRESSURE SENSOR
Series 117B
1
1.0 INTRODUCTION
The Model 117B Conformal Sensor measures
pressure inside metallic cartridges and paper or
plastic shotshell, during firing of the round, without
drilled holes in the round.
The sensor is mounted flush with the chamber walls,
matching the curvature exactly. The expanded
cartridge or shotshell transmits forces through the thin
wall to the sensor.
The Model 117B is a conventional charge output
type sensor using synthetic quartz as the piezoelectric
sensing material.
An alignment guide now standard on all 117B
Models, simplifies installation by automatically
controlling rotational alignment of the sensor, leaving
only the depth adjustment consideration.
2.0 DESCRIPTION
Refer to enclosed installation drawing for outline
dimensions and physical description.
The basic sensor is a probe design with captivated
hollow clamp nut. The clamp nut rotates
independently of the probe body and serves to lift the
sensor out of the mounting port as it is unscrewed.
The alignment device consists of a pin and slotted
clamp assembly which fits tightly over the collar of
the sensor.
The hardened steel pin is accurately aligned with the
axis of the diaphragm curvature and when assembled
into a precisely drilled mating hole in the barrel or
calibration chamber, achieves near perfect rotational
alignment of sensor diaphragm.
The slotted clamp arrangement allows for tolerance in
the location of the guide pin hole in an axial direction
on the test barrel or calibration adaptor.
The precise depth adjustment is obtained by the use
of the correct thickness spacer selected from a set of 9
spacers of various thicknesses supplied with each
sensor.
Once the proper thickness spacer is found, removal
and re-installation now becomes a routine matter.
3.0 INSTALLATION
3.1 PORT PREPARATION
Prepare mounting port in accordance with installation
drawing 117-20 (XX)-90 supplied as part of this
manual.
NOTE: The installation port for the 117B is identical
to that for the 117A.
Drill guide pin hole as shown in installation drawing,
paying particular attention to locating C/L of hole
exactly on C/L of barrel.
Do not use a drill that is worn, as this may cause the
hole to be slightly undersized and the guide pin may
bind as it is drawn into the hole.
It is extremely important that the guide pin hole be
drilled parallel to the sensor mounting port to permit
the guide pin to move freely into the hole.
NOTE: Each model variation of the 117B is designed
to fit in a specific location (measured from the bolt
face) on a specific ammunition caliber. Changing
location and/or caliber will cause a mismatch of
diaphragm curvature with cartridge case diameter
since most cartridge cases are tapered.
3.2 INSTALLING THE SENSOR
After mounting holes have been prepared, proceed
with installation as follows:
1. On most models of 117B, it is not important
which side of the sensor is mounted toward
the muzzle.
However, on certain types of ammunition
(such as 20 mm cannon) which have a severe
taper, the diaphragm has a matching taper in

Series 117B
2
the curvature. In these latter cases, the
sensor forward side is identified with the
legend “FWD”etched on the guide collar to
which the slotted clamp is attached. The
clamp must be removed to find this legend.
If it does not appear, the sensor may be
mounted with either side toward the muzzle.
2. Loosen slotted clamp, but do not remove
clamp.
3. Select the middle thickness (.014) spacer
from the set of nine (065A19) supplied and
place it around sensor barrel.
4. Begin threading the sensor clamp nut into
the threaded mounting port, sliding slotted
clamp fore and aft as needed to allow guide
pin to fully enter hole.
Continue to turn clamp nut into hole by hand
or using 5/16 open end wrench.
Do not tighten when sensor bottoms.
5. Now tighten the screw closing slotted clamp.
6. Using open end wrench, tighten sensor
clamp nut.
NOTE: It is not necessary to put large amounts of
torque on this nut since a pressure seal is not
necessary. Approximately 5 to 10 ft. lbs. is
sufficient.
7. Now inspect flushness of diaphragm with
inside surface of chamber. This can be
accomplished visually in most cases.
If the diaphragm extends too deeply into the
chamber, select a thicker spacer and repeat
mounting procedure.
If the diaphragm is too deeply recessed,
select a thinner spacer and remount.
Once the proper thickness is found for
perfect flushness, the sensor may be
removed and reinstalled using this same
spacer and the proper depth will be achieved
each time.
NOTE: For best accuracy of results, use
same charge amplifier for calibration and for
actual operation. Use long TC for
calibration, medium or short TC for best
drift free operation.
4.0 POLARITY
Polarity of the Model 117B is negative i.e., the
charge output is negative for increasing pressure
input, making it compatible with inverting type
charge amplifiers.
5.0 CALIBRATION
Calibration of the Models 117B is facilitated by a
calibration adaptor which exactly matches the
chamber dimensions of the cartridge under test. An
actual cartridge case is hydraulically pressurized with
reference pressure to obtain a point-by-point sensor
calibration.
These calibration adaptors can be fabricated by the
user or can be purchased from PCB as our Model
090B calibration adaptor. Simply specify caliber and
longitudinal location of sensor.
For most rimfire applications, the sensor is located
.25 inches forward of the boltface.
For center fire cartridges a location .175 inches back
from the cartridge shoulder is preferred. Consult PCB
for recommendations on sensor locations if questions
arise.
Since most cartridge cases are tapered and diameter is
dependent upon longitudinal location, this location
may not be changed after the sensor is fabricated
since it is essential for proper operation that the
sensor curvature exactly match chamber curvature.

5.1 LOW-END NONLINEARITY
It will be noticed during calibration, especially with
metallic cartridges, that a certain amount of pressure
is necessary before linear output is attained from the
conformal sensor.
This is due to the fact that since the cartridge cases
are made nominally smaller in diameter than the
chamber to allow easy insertion and extraction, the
case must be expanded slightly by the internal
pressure before force can be transmitted to the sensor.
See the enclosed guide “An Improved Technique for
Utilization of Conformal Ballistics Sensor Calibration
Data”for methods of dealing with this topic.
6.0 MAINTENANCE
It is essential for normal operation of the Model 117B
that the insulation resistance be maintained above
1012 ohms. If insulation resistance should deteriorate,
wipe connector with clean cloth or paper wipe dipped
in a solvent compatible with Teflonsuch as
isopropyl alcohol, then bake in oven at 250F for ½
hour.

AN IMPROVED TECHNIQUE FOR
UTILIZATION OF CONFORMAL BALLISTICS
SENSOR CALIBRATION DATA
1
The PCB Series 117B Conformal Ballistics Sensor
(patented) measures chamber pressure in a novel
manner.
The sensitive surface of the sensor, when properly
installed in the gun chamber, conforms or blends in
precisely with the inside surface of the chamber actually
forming a portion of the wall adjacent to the cartridge
case.
When the round is fired, the pressure builds up rapidly
inside the case, obturating the case outward against the
chamber. The force, transmitted through the thin
cartridge case wall stresses the sensor crystals producing
an output charge analogous to chamber pressure.
An exclusive calibration technique has been developed
in conjunction with the conformal sensor, consisting of a
simulated gun chamber which positions the sensor at the
same location as in the test barrel and provides for
hydraulic pressurizations of an actual cartridge case.
Using this system and a reference standard pressure
source, a point by point calibration is performed on
samples of the actual lot of ammunition under test to
take into account transmissibility characteristics of the
cartridge case for each lot of ammunition.
Because a certain amount of pressure is required to fully
obturate the cartridge case in the test chamber, a rather
severe non-linearity is exhibited over the first several
thousand psi of input pressure, i.e. until the cartridge
case is pressed firmly against the inside chamber walls.
Figure 1 illustrates a typical calibration result with .22
caliber rimfire ammunition.
Figure 1: Typical calibration graph
Conformal sensor with .22 caliber rimfire.
As shown in figure 1, the best straight line that can be
drawn through the majority of the data points in the
linear portion of the curve, does not pass through the
origin.
Because of this, the widely accepted zero based best
straight line method of linearity determination cannot be
applied to the conformal sensor. Also, the actual
sensitivity of this sensor may only be specified at one
input pressure level since the sensitivity is not a
constant, but varies with input pressure level.
This paper outlines a simple alternative approach to
utilization of conformal sensor data.
The most universally accepted method of defining
conventional sensor nonlinearity is the full scale error
band method used in conjunction with the zero based
best straight line.

Figure 2: Zero based best straight
line method of linearity determination.
To utilize the zero based best straight line method, the
corresponding value of the sensor output is plotted for
each value of input measurand up to full scale as shown
in Figure 2.
A straight line, intercepting the origin as shown, is fitted
to the data points by equalizing the error between the
points below the line and the points above the line.
Error bands, as delineated by the instrument
specification are constructed as shown in figure 2.
Typically, plus and minus one or two percent of full
scale is specified for quartz sensors.
An acceptable instrument is then defined as one whose
data points all fall within this error band.
The "sensitivity" of an instrument so calibrated is simply
the full scale output (charge or voltage) divided by full
scale input pressure, where F.S. output is determined by
the straight line as defined above.

ySensitivit (Eq. 1)
The units for sensitivity are commonly pC/psi or
mV/psi.
Note that in this case, the sensitivity is identical to the
slope of the line, since the line does intersect the origin
by previous definition.
The general equation for a straight line in terms of the
dependent variable is:
y = mx + b (Eq. 2)

Where C is the X-axis intercept.
Equation 4 is directly applicable to the conformal sensor
even through the X variable (psi) becomes the
dependent variable when using the sensor output to
determine pressure.
Consider again the calibration graph of a typical
conformal sensor, shown in figure 4.
To calibrate a conformal sensor, the input pressure is
increased in discrete steps from 0 psi to full scale with
the corresponding output recorded at each step. The
information must be taken only once and only with
increasing pressure. A repeat run on the same cartridge
case will not yield the same values as the initial run due
to work hardening of the cartridge case metal.
Figure 4
At the lower pressures, the sensor has very little output
because there is a certain amount of clearance between
the cartridge case and the chamber wall. Obturation of
the cartridge occurs in this region.
However, when obturation is complete, the sensor
output is then linear with pressure from this point up to
maximum rated pressure.
In the past, a common procedure has been to calibrate
the conformal at the expected nominal pressure, deriving
a sensitivity at this point, e.g. point Po, Qo in figure 4.
The sensitivity determined by dividing output Qo by
corresponding pressure input Po, would then yield the
exact result if the input pressure was always exactly Po.
However, should the input pressure change to Pa, it is
clear that the reading would be in error, as shown in Fig.
4, since the actual sensitivity of the instrument is not the
same at Po, as it is at Pa.
A solution to this problem lies in utilization of equation

The straight line is the best line that can be constructed
through the linear portion of the curve as shown in
Figure 4 and the pressure intercept (or offset) is the
point at which this line crosses the pressure axis, in psi.
Instead of establishing the sensitivity parameter (which
has been shown to have little meaning for this sensor)
the user now determines the slope as defined in Eq. 6
and the accompanying pressure offset by constructing
the best straight line as described previously.
Pressures P1 and P2 are arbitrarily established at some
point well above and well below the expected nominal
pressure of the test.
The corresponding outputs at these pressures should be
an average of at least 20 cartridges taken from the same
lot of ammunition as is under test.
The main difference between utilization of the data with
this method is that now a constant (pressure offset) must
be added to each reading. However, this can be easily
handled by most data reduction methods in use today.
Example:
In actual practice, this is how a conformal sensor/charge
amplifier system could be utilized:
Assume that averaging the data from 20 consecutive
calibration runs performed on a conformal sensor
yielded a slope of .04 pC/psi and an intercept of 7,500
psi, determined by constructing the best fitting straight
line as described previously.
Assume also that average expected peak pressure is
25,000 psi.
Approximate full scale charge output is:
pC1000pC/psi.04psi25,000


Set range of charge amplifier output to 1000 pC/volt (or
other desired range).
Read peak output voltage of .800 volts during test.
Peak indicated charge is then:
1000 pC/volt x .80 volts = 800 pC
Indicated peak pressure is:

(pk)Pressure 
psi7,500
pC/psi.04 pC800
P
P = 20,000 psi + 7500 = 27,500 Psi
As previously stated, this method will yield accurate
results anywhere within the linear portion of the sensor
calibration curve without inherent errors due to
variability of sensitivity with pressure level.
Accuracy should be close to that expected for standard
piezoelectric sensors within the limitation of
transmissibility variations in the cartridge cases.
Simplified standardization techniques for Conformal
Sensor
The technique described by the previous example
outlines one basic method of output signal utilization.
This method in actual practice may be cumbersome for
repeated testing because of the conversions that must be
made from measured charge output to indicated peak
pressure.
Other system scaling methods exist which further
simplify signal utilization.

Dial Gain Standardization
Many charge amplifiers feature a calibrated gain pot for
dialing in sensor sensitivity for the purpose of setting
system sensitivity to standardized unit of output voltage
(PCB Model 462A).
To utilize such amplifiers, dial in the actual value of
slope as determined by the calibration graph for the
particular ammunition lot.
Using the slope value effectively displaces the
calibration curve to pass through the origin (0) of the
calibration graph.
See Figure 5.
Figure 5
The indicated peak pressure P2 from the conformal,
which through scale factoring can be read to read
directly in psi (on a digital peak meter for example) is
simply added to the offset pressure to arrive at true peak
pressure, P1 + P2
This process can be further refined to, include a variable
voltage source as a bias in series with the output of the
charge amplifier. This voltage bias can be set to
simulate the offset pressure, and then the true peak
pressure can be read directly. (See figure 6 on the next
page)
Example:
Assume a 20 round calibration lot and attendant graph
yield a slope of .250 pC/psi and an offset of 5,000 psi.
Proceed as follows:
Dial the slope (.250) into the dial gain pot and select a
convenient full scale range over which to operate.
For example, for an expected full scale range of 40,000
psi, select 10,000 units/volt.
Now the indicated peak pressure can be read directly
from a digital peak holding meter such as the PCB
Model 451B.
If the offset supply is not used, simply add the offset
pressure (5,000 psi) to the indicated pressure to arrive at
true peak pressure.
If an offset supply is used as in figure 6 simply dial in
the offset voltage equivalent to offset pressure. Now the
offset will be automatically added and the true peak
pressure can be read directly from the peak meter.

Calibrate Signal Insertion
Another method that is useful especially when utilizing
a storage oscilloscope readout is to use a charge
calibrator to inject a full scale charge signal into the
charge amplifier. Multiply the sensor slope value by full
scale pressure to find full scale picocoulombs.
40,000 psi x .250 pC/psi = 10,000 pC
Set the charge calibrator for 10,000 pC and apply this
signal to the input of the amplifier. Now adjust the gain
of the oscilloscope (or charge amplifier if gain adjust is
available) to make full scale equal to a selected number
of oscilloscope divisions.
For example: 6 Div = 40,000 psi
Now the peak value can be determined from the
oscilloscope face or scope photo using a variable scale
or other interpolative methods.
Then, add the offset pressure to this value to determine
true peak pressure.
