3710 series DC 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 3710
Series MEMS DC 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 Common Applications and Features
The 3710 Series MEMS DC Accelerometers achieve true DC
response for measuring uniform (or constant) acceleration and
low-frequency vibration. For this reason, they are often used
to:
Perform ride quality assessments of elevators, automo-
biles, trains, and amusement park rides.
Analyze the low frequency characteristics of buildings,
bridges, and large aerospace objects.
Acquire tilt and orientation data for feedback control and
stabilization purposes.
Because of the critical nature of these and similar test applica-
tions, all 3710 series MEMS DC Accelerometers have been
designed and manufactured with the following common char-
acteristics:
Rugged, all-welded titanium housing insures reliability
and durability in demanding applications and environ-
ments.
Built-in microelectronics provide conveniently standard-
ized sensitivities and low-noise output signals unmatched
by similar sensing technologies.
Internal voltage regulator allows sensor to be powered
from virtually any unregulated DC voltage source, such as
a bench-top power supply or portable battery source.
Gas damping extends the upper frequency range, attenu-
ates unwanted high-frequency vibration, and provides
stable performance over the entire operating temperature
range.
Hermetic, multi-pin connector provides a reliable connec-
tion even under the harshest environmental conditions.
3.0 Principle of Operation
The sensor element of the 3710 series features a proof mass,
ring frame, and attachment system between the two. These
features are bulk micro machined from the same single-crystal
silicon wafer. The movement of the proof mass is directly
affected by acceleration applied in the axis of sensitivity.
The sensor element is connected as a bridge element in the
circuit. The electrical characteristics of one portion of the
bridge increase in value while the characteristics of the other
portion decrease when exposed to acceleration. This approach
minimizes common mode errors and improves non-linearity.
A selection of full scale measurement ranges is attained by
modifying the stiffness of the suspension system of the proof
mass. A high natural frequency is accomplished through the
combination of a lightweight proof mass and suspension stiff-
ness.
Ruggedness is enhanced through the use of mechanical stops
on the two outer wafers to restrict the travel of the proof mass.
Damping is used to mitigate high frequency inputs.
The sensor elements use squeeze-film gas damping that is near
critically damped. This is the result of the movement of the
proof mass pressing on the gas in the gap between it and the
outer sensor layer. Damping helps prevent the output of the
accelerometer from becoming saturated, as would happen
when the resonance of an accelerometer with no damping is
excited by random vibration. The advantage of gas damping
over liquid damping is that it is minimally affected by temper-
ature changes.
The 3710 series accelerometers contain conditioning circuitry
that provides a high sensitivity output. This IC also provides
compensation of zero bias and sensitivity errors over tempera-
ture.
An on-board voltage regulator allows a typical excitation
range of 6 to 30 VDC with <30 mA current draw. The 3710
series features a ± 2 V Full Scale zero based output referenced
to power ground. A negative voltage generator provides a suf-
ficient signal swing for negative acceleration outputs with a
positive voltage swing of +4.0 V accommodating positive
accelerations.
An automated calibration step is conducted at the completion
of the accelerometer assembly at discrete temperatures over
the specified operating temperature range. The IC features an
on-chip temperature sensor for accurate thermal corrections.

4.0 Typical Measurement System
The 3710 series DC Accelerometers are available in a uniaxial
or triaxial package, with the uniaxial model being the 3711
version and the triaxial model being the 3713 version. The
output signal is routed to follow-on signal conditioning via a
hermetic four-pin receptacle and associated cable assembly;
Model 010 series for the 3711 uniaxial version, and Model
037 series nine-pin cable assembly for the 3713 triaxial ver-
sion. Since the High Sensitivity DC Accelerometers contain a
built-in voltage regulator, they may be powered from virtually
any 6 to 30 VDC power source without adversely affecting
sensor performance. PCB signal conditioners available are
Model 445B01, a single-channel, line powered signal condi-
tioner for the uniaxial 3711series DC accelerometers and
Model 478A05, a three-channel, line-powered signal condi-
tioner for the triaxial 3713 accelerometer. Consult PCB Appli-
cation Engineering for additional signal conditioning options.
The output from the signal conditioner is typically routed to
readout instrumentation such as oscilloscopes or various mod-
el data acquisition instruments.
5.0 Sensor Installation
When choosing an installation technique, be certain to care-
fully examine the different application characteristics that may
affect sensor performance. Characteristics such as mounting
location may limit the use of large mounting blocks or the
amplitude range may necessitate the use of a stud mount rather
than using adhesive. A summary of the recommended mount-
ing methods is provided below.
Stud Mount: Recommended for permanent mount applications
or in test situations that require a rugged or secure installation.
The necessary information, including surface finish, mounting
hole dimensions, and recommended mounting torque for in-
stalling the sensor is listed on the enclosed Sensor Installation
Drawing. It is recommended that an experienced technician or
machinist with good machining capabilities adequately pre-
pare the surface.
Adhesive Mount: Recommended for temporary mounting of
the sensor or when the test object surface cannot be properly
prepared for stud mounting. Wax works well for temporary
mount applications under conditions where the operating tem-
perature will not melt the wax or the acceleration levels will
not dislodge the sensor from the test object. Cyanoacrylate-
based, “quick-bonding” adhesives provide a quick mounting
method, while two-part epoxies can be used for a more secure
mount. To remove an adhesively mounted sensor, it is best to
place an open-ended wrench over the sensor and twist it to
shear the adhesive bond. Striking the sensor with a hammer or
other object may permanently damage the sensor.
Easy Mount Clip: Recommended when frequent installation
and removal of Series 3710 series accelerometers is desired.
The Easy-Mount Clip can either be stud mounted or adhesive-
ly mounted to the test structure. (If adhesively mounting the
clip, detach the sensor from the clip first, as excessive adhe-
sive may creep through the mounting holes and adhere to the
sensor. This will make separation and removal from the clip
difficult.) Once the Easy-Mount Clip has been attached to the
test structure, the sensor can be easily snapped into and out of
the clip. Over time, the Easy-Mount Clip must be replaced as
it will “wear-out” and eventually lose its ability to securely
hold the sensor.
6.0 Powering
The 3710 Series contains built-in microelectronics that will
operate from any PCB Series 445 or Series 478 Sensor Signal
Conditioner. These signal conditioners provide the necessary
voltage and current required for all of the powering options
available on the 3710 series.
The 3710 series may also be powered by other voltage sources
such as DC voltage laboratory supplies, automotive or marine
batteries, or low-voltage supplies designed for powering PC
Board components. If you decide to not use a Series 445 or
478 Series Signal Conditioner, insure that the source provides
power within the excitation voltage range listed on the specifi-
cation sheet for that model. It is important to note that since
the accelerometers contain a built-in voltage regulator, precise
calibration of the power source is generally not required.
7.0 Operation
After the sensor has been installed and the cable connected for
proper operation, there are a couple of measurement points to
take note of:
To take advantage of the DC response of the accelerome-
ter, the readout device must be in a DC coupled state.
Consult the appropriate manufacturer or product manual
for your readout device for details.
Because the 3710 series can measure static (constant)
accelerations, the DC offset voltage will be affected by
the positional alignment relative to the Earth’s gravity. In
other words, when the sensor is mounted perpendicular
with the Earth’s surface, the offset will equal that as spec-
ified on the calibration certificate for “zero-g offset volt-
age.” If the sensor is mounted parallel with the Earth’s
surface, the sensor will be experiencing 1 g of accelera-
tion and the offset voltage will increase by the sensitivity
of the accelerometer.

If the sensor is extended, in the case of an integral cable
sensor, or a cable length other than 10 ft is used, in the
case of sensor with an integral connector, the offset volt-
age will change. To determine the accelerometer’s offset,
rotate the unit 90° so that the sensor is on its side with the
sensing axis perpendicular to Earth’s gravity and record
the DC output. This value is the new “zero-g offset volt-
age.”
To insure that ground loops are not induced, the shield
should only be terminated at one end. Typically, the
shield of the cable is tied to the sensor housing. If the sen-
sor is mounted with an isolation pad (or other form of
electrical isolation) from the test structure, then the shield
should be tied to signal ground at the instrumentation end.
Otherwise, leave the cable shield floating or not connect-
ed at the instrumentation end.
8.0 Sensor Verification
If the sensor has been handled in a rough manner or before
using a sensor for a critical measurement application, it is a
good idea to verify that the sensor’s sensitivity is still within
specification. An accurate static calibration of the 3710 series
can be performed using the Earth’s Gravitational Field as a
reference. The sensor can simply be “flipped” (rotated 180°)
in the Earth’s Gravity to obtain the scaling factor (sensitivity)
and DC offset. First, place the accelerometer in a +1g orienta-
tion so that the base is resting on the table and the model num-
ber is facing up. The sensing axis will be parallel with the
Earth’s gravity with the sensor experiencing +1g acceleration.
Record the DC output by using a DVM. Then rotate the sensor
180° so that the sensor is inverted (the top of the sensor is rest-
ing on the table) and the sensor is experiencing –1g accelera-
tion. Record the DC output. To calculate the sensitivity of the
accelerometer, refer to equation 8.1.
Sensitivity = (+1g) –(-1g) Eq 8.1
2
9.0 Sensor Calibration
Due to ISO 9001, ISO Guide 25, or other contractual require-
ments, it may become necessary to send the accelerometer
back to PCB for recalibration. In this case, a complete back-
to-back frequency response test will be performed and the
“zero-g” offset voltage will be checked with NIST traceable
equipment.
10.0 Maintenance and Repair
Because of the sophisticated nature of PCB instrumentation,
field repair of the equipment is not recommended. Most PCB
sensors are of modular construction and are factory repairable.
A repair or replacement quotation is available at no charge.
Before returning equipment for repair, it is recommended that
the user confer with a factory application engineer (or inter-
national representative) to first troubleshoot the problem.
11.0 Return Procedure
To expedite the repair process, contact a factory Application
Engineer to obtain a Return Material Authorization (RMA)
number prior to sending equipment to the factory. Please have
information, such as model number, serial number and de-
scription of the problem, available.
Customers outside the U.S. should consult their local PCB
distributor for information on returning equipment. For excep-
tions to this guideline, please contact the International Sales
department to request shipping instructions and an RMA.
