3504 Series Piezoresistive Shock Accelerometer Operating Guide
1
1.0 Introduction
This Operating Guide contains information that will
familiarize the user with the basic operation and installation of
the 3504 Series Piezoresistive (PR) Shock Accelerometers.
However, it is not intended to cover all of the specific
measurement challenges that one may encounter while using
the device. Therefore, if you have detailed questions or are
unsure of how to properly operate the sensor after reading this
Operating Guide, please contact a PCB Application Engineer
using our 24-Hour SensorLineTM at 716-684-0001.
2.0 Principle of Operation
PR accelerometers are passive devices which require stable
external power, typically a regulated dc voltage such as 10V,
or more recently 5V or 3.3V to operate with new electronics.
They include silicon strain-sensing elements which change
resistance proportionally to the applied acceleration, half of
which increase in value with positive acceleration, and half
which decrease, as shown in the Wheatstone-bridge circuit of
Figure 1. All four resistors in the sensors are active, providing
twice the sensitivity of half-bridge device for the same strain
levels. The sensitivity of the bridge is proportional to the
Excitation voltage.
Figure 1 –Wheatstone Bridge Circuit
Terminology related to PR devices includes:
ZMO –Zero Measurand Output, also called bias or offset, is
the output when no input acceleration is applied.
TSS –Thermal Sensitivity Shift, the change of sensitivity due
to temperature. The sensors are uncompensated, so they
display a slight linear decrease in sensitivity as temperature
increases.
TZS –Thermal Zero Shift, the change in ZMO due to
temperature. This is less predictable, and from unit to unit may
have positive or negative slope, although it will be stable for
any one unit.
3.0 Features
The 3504 Series use micro-electromechanical systems
(MEMS) technology, in which all structural and electronic
components are manufactured in silicon using electronic
microfabrication technologies. MEMS devices are preferred in
many high shock impact measurements over piezoelectric
elements, since these PR devices are inherently DC coupled,
exploit the strength of single crystal silicon (SCS) and display
minimal zero shift. However, an additional characteristic of
SCS is extremely low internal damping, which results in
susceptibility to overshoot and resonant excitation. Although
the stiffness of silicon can allow extremely high resonant
frequency in some MEMS shock sensor designs, PCB MEMS
uses a different approach in which the resonance frequency is
intentionally lowered to reduce the response to higher
frequency energy present in shock events. The relatively low
resonance also creates displacements of the seismic element
sufficient to introduce squeeze film damping. Air is used rather
than a fluid so thermal effects on damping are negligible.
Manufactured using recent advances in semiconductor
processing, the PCB MEMS design aims at an optimally
damped sensor with sufficient bandwidth to accurately track
rigid-body vehicle deceleration. Resonant amplification is
reduced by orders of magnitude, and survivability is increased.
Ruggedness is enhanced through the use of mechanical stops.
The sensors are manufactured as the sandwich of three wafers,
with the active core surrounded by the two outer wafers which
provide hermetic protection and restrict the travel of the proof
mass.
Because many such applications are coupled with battery
powered conditioning and data acquisition, the PCB MEMS
was designed with relatively high value resistors
(approximately 10 times that of other devices) to maximize
battery life.
4.0 Common Applications
The 3504 Series PR Shock Accelerometers achieve true DC
response for measuring long duration shock. For this reason,
they are preferred for applications in which integration from
acceleration to velocity or displacement may be performed.

These are violent events. Because of the critical nature of these
and similar test applications, PCB MEMS accelerometers have
been designed and manufactured with the following common
characteristics:
Rugged, all-welded titanium housing insures reliability
and durability in demanding applications and
environments.
The MEMS sensor includes overrange stops set at
approximately twice the full range.
Gas damping attenuates unwanted high-frequency output.
5.0 Sensor Installation
The 3504 series DC Accelerometers are available in titanium
packages and have a 10-32 threaded base that is supplied with
both standard and metric adaptor studs.
When choosing a mounting method, consider closely both the
advantages and disadvantages of each technique.
Characteristics like location, ruggedness, amplitude range,
accessibility, temperature, and portability are extremely
critical. However, the most important and often overlooked
consideration is the effect the mounting technique has on the
high-frequency performance of the accelerometer.
Shown in figure 2 are six possible mounting techniques and
their effects on the performance of a typical piezoelectric
accelerometer. (Note that not all of the mounting methods
may apply to your particular sensor). The mounting
configurations and corresponding graph demonstrate how the
high-frequency response of the accelerometer may be
compromised as mass is added to the system and/or the
mounting stiffness is reduced.
Figure 2. Assorted Mounting Configurations and Their
Effects on High Frequency
5.1 STUD MOUNT
This mounting technique requires smooth, flat contact surfaces
for proper operation and is recommended for permanent
and/or secure installations. Stud mounting is also
recommended when testing at high frequencies.
NOTE: Do NOT attempt mounting on curved, rough, or
uneven surfaces, as the potential for misalignment and limited
contact surface may significantly reduce the sensor’s upper
operating frequency range.
STEP 1: First, prepare a smooth, flat mounting surface, then
drill and tap a mounting hole in the center of this area as
shown in Figure 3 and in accordance with the enclosed
Installation Drawing.
Figure 3. Mounting Surface Preparation
A precision-machined mounting surface with a minimum finish
of 63 in (0.00016 mm) is recommended. (If it is not possible
to properly prepare the test structure mounting surface,
consider adhesive mounting as a possible alternative). Inspect
the area, checking that there are no burrs or other foreign
particles interfering with the contact surface.

STEP 2: Wipe clean the mounting surface and spread on a
light film of grease, oil, or similar coupling fluid prior to
installation as shown in Figure 4.
Figure 4. Mounting Surface Lubrication
Adding a coupling fluid improves vibration transmissibility by
filling small voids in the mounting surface and increasing the
mounting stiffness. For semi-permanent mounting, substitute
epoxy or another type of adhesive.
STEP 3: Screw the mounting stud into the base of
accelerometer and hand-tighten (this step is unnecessary for
units having an integral mounting stud). Then, screw the
sensor into the tapped hole that was prepared in the test object.
Tighten the unit in place by applying, with a torque wrench,
the recommended mounting torque, as listed on the enclosed
Installation Drawing.
NOTE: It is important to use a torque wrench during this
step. Under-torquing the sensor may not adequately couple
the device; over-torquing may result in stud failure.
5.2 ADHESIVE MOUNT
Adhesive mounting is often used for temporary installation or
when the test object surface cannot be adequately prepared for
stud mounting. Adhesives like hot glue and wax perform well
for temporary installations whereas two-part epoxies and
quick-bonding gels (super glue) provide a more permanent
installation. Two techniques are used for adhesive mounting;
they are via an adhesive mounting base (method 1 below) or
direct adhesive mounting (method 2 below).
NOTE: Adhesively mounted sensors often exhibit a reduction
in high-frequency range. Generally, smooth surfaces and stiff
adhesives provide the best high frequency response.
METHOD 1 - Adhesive Mounting Base
This method involves attaching a base to the test structure,
then securing the sensor to the base. This allows for easy
removal of the accelerometer. Also, since many bases are
manufactured of “hard-coated” aluminum, they provide
electrical isolation to eliminate ground loops and reduce
electrical interference that may propagate from the surface of
the test object.
STEP 1: Prepare a smooth, flat mounting surface. A
minimum surface finish of 63 in (0.00016 mm) generally
works best.
STEP 2: Stud-mount the sensor to the flat side of the
appropriate adhesive mounting base according to the
guidelines set forth in STEPS 2 and 3 of the Stud Mount
Procedure presented above.
STEP 3: Place a small portion of adhesive on the underside of
the mounting base (the underside is discernable by the
concentric grooves which are designed to accept the adhesive).
Firmly press down on the assembly to displace any extra
adhesive remaining under the base as shown in figure 5.
Figure 5. Mounting Base: Adhesive Installation
METHOD 2 - Direct Adhesive Mount
For restrictions of space or for convenience, most sensors can
be adhesive-mounted directly to the test structure (an
exception being units having integral mounting studs).
STEP 1: Prepare a smooth, flat mounting surface. A
minimum surface finish of 63 in (0.00016 mm) generally
works best.
STEP 2: Place a small portion of adhesive on the underside of
the sensor. Firmly press down on the top of the assembly to
displace any adhesive as shown in Figure 6. Be aware that
excessive amounts of adhesive can make sensor removal
difficult. Also, adhesive that may invade the tapped mounting
hole in the base of the sensor will compromise future ability to
stud mount the unit.

Figure 6. Direct Adhesive Mounting
5.2-1 ADHESIVE MOUNT REMOVAL (other than wax)
NOTE: A debonder should always be used to avoid sensor
damage.
To avoid damaging the accelerometer, a debonding agent must
be applied to the adhesive prior to sensor removal. With so
many adhesives in use (everything from super glues, dental
cement, epoxies, etc), there is no universal debonding agent
available. The debonder for the Loctite 454 adhesive that
PCB offers is Acetone. If you are using anything other than
Loctite 454, you will have to check with the individual
manufacturers for their debonding recommendations. The
debonding agent must be allowed to penetrate the surface in
order to properly react with the adhesive, so it is advisable to
wait a few minutes before removing the sensor.
After the debonding agent has set, you can use an ordinary
open-end wrench if the accelerometer has a hex base or square
base, or the supplied removal tool for teardrop accelerometers.
After attaching either, use a gentle shearing (or twisting)
motion (by hand only) to remove the sensor from the test
structure.
6.0 Power
Normally PR devices are powered with regulated Excitation,
since the sensitivity is proportional to input voltage. Although
for the 3504 Series the proportionality is very good (due to
minimal self heating of the comparatively high-resistance
elements) generally it is recommended to obtain the calibrated
sensitivity using the intended Excitation voltage. In integrated
applications, in which the data acquisition is powered by the
same voltage that supplies the bridge, it is possible to reduce
the effect of variations in Excitation on overall system
sensitivity by using the excitation voltage as the reference for
the data acquisition.
7.0 Typical Measurement System
The output from the sensor is typically routed to bridge
conditioner then oscilloscopes or various data acquisition
instruments. Consult PCB Application Engineering for
additional signal conditioning options. To take advantage of
the DC response of the accelerometer, the readout device must
be in a DC coupled state. Consult the appropriate
manufacturer or product manual for your readout device for
details.
8.0 Sensor Verification
Generally the ZMO of a PR transducer is a good measure of
the health of the transducer. This is possible using PCB
standard cabling, Input Resistance (from Red to Black) or
Output Resistance (from Green or Yellow to White), but this is
less commonly used to check the condition since resistance
changes with temperature. A thorough check of the health
(suggested both before and after an expensive test) must
include calibration of the sensitivity.
In some laboratories which use piezoresistive transducers, it is
customary to check the continuity and gain of the conditioning
and data acquisition system using a technique called “Shunt
Calibration”. By temporarily unbalancing the bridge with a
shunt resistor placed in parallel with a leg of the bridge
(usually between the “+ Sig” wire and either the “+ Exc” or “–
Exc”), dc shifts of the offset are created. Whereas the process
does not calibrate the transducer, it is a check of system gain,
with accuracy of the resultant dc shift in output dependent on
the degree that the resistances of both the leg of the bridge and
the shunt resistor are accurately known. Among other sources
of variability, temperature can change the value of the
resistors, and therefore the Shunt Calibration output. The user
should be aware that because the 3504 Series are full bridge
transducers, all legs are active and will have temperature
coefficients typical of piezoresistive sensors (approximately
+0.1%/degree C).
9.0 Sensor Calibration
For shock accelerometers, the most appropriate, accurate and
reliable calibration is with a comparison shock using a back-
to-back reference and pneumatic exciter, as described in ISO
16063-22, “Methods for the calibration of vibration and shock
transducers —Part 22: Shock calibration by comparison to a
reference transducer.” PCB offers this calibration as a service.
